Smart home gear has a habit of going on sale right when you least expect it, and 2026 is shaping up to be a great year to buy discounted. The question is no longer whether to automate your home on a budget, but which discounted devices actually deserve a spot on your wall or in your outlet. After comparing the current deals side by side, two picks rise to the top: the Google Nest Learning Thermostat (4th gen) for anyone who wants a single upgrade with a real payoff on their energy bill, and the EIGHTREE Smart Plug 4-Pack for the cheapest possible entry into voice control.

The main tradeoff in this lineup comes down to ambition versus simplicity. Thermostats demand more money, wiring knowledge, and patience, but they can pay for themselves over time. Smart plugs cost almost nothing, work in minutes, and control only what you plug into them. Within the plug category, there is a second tradeoff worth knowing about before you check out: Matter-compatible plugs like the Linkind future-proof your setup across Apple Home, Alexa, and Google, while cheaper plugs like the GHome Mini lock you into a single app ecosystem. My goal here is to help you match the discount to the buyer, not just chase the lowest price tag.
Key Takeaways
- The Nest Learning Thermostat (4th gen) delivers the biggest long-term value of any deal here, with up to 31% savings on heating and cooling, but it carries the highest upfront cost.
- The Amazon Smart Thermostat is the best budget thermostat deal if you already have a C-wire, costing far less than the Nest while covering most of the same basics.
- Among plugs, the Linkind Matter Smart Plug is the pick for multi-platform households (especially Apple Home users), while the EIGHTREE 4-Pack wins on pure value for Alexa and Google users.
- Every plug in this roundup is limited to 2.4GHz Wi-Fi, so check your router settings before buying any of them.
- The GHome Smart Plug Mini is the cheapest way to automate lamps and fans, but its 10A rating rules out higher-draw appliances like space heaters.

More Details on Our Top Picks
Google Nest Learning Thermostat (4th gen) + Nest Temperature Sensor (2nd gen) – Silver
This bundle is the most expensive item in the lineup, and I have placed it first anyway, because a discount on the Nest Learning Thermostat buys more genuine capability than anything else here. The standout feature is right in the name: it learns your schedule and temperature preferences over time, then builds an adaptive routine without you programming anything. Paired with the included second-generation temperature sensor, it can prioritize the room you actually occupy instead of the hallway where the thermostat happens to hang. That combination is what drives the up to 31% savings on heating and cooling, and it is a claim neither the Amazon Smart Thermostat nor any plug in this roundup can approach.
Compared with the Amazon Smart Thermostat, the Nest justifies its premium in three ways: a display 60% larger than the previous generation, support for the Nest Temperature Sensor for real zoning, and no C-wire requirement in most homes, which spares many buyers an electrician visit. The Amazon unit counters with a dramatically lower price and guided DIY setup, so the honest framing is this: the Nest is the better thermostat, and the Amazon is the better bargain. Where the Nest pulls ahead for the long haul is compatibility with Matter, Alexa, Siri, and Google Assistant simultaneously, meaning it will not become obsolete if you change ecosystems down the road.
The tradeoffs are real, though. Full functionality depends on Wi-Fi, buyers without prior wiring experience may find installation confusing despite the app’s guidance, and even discounted, it costs several times more than a four-pack of smart plugs. This pick makes the most sense for a homeowner planning to stay put long enough for the energy savings to offset the price.
Pros:- Up to 31% savings on heating and cooling bills can offset the purchase price over time
- Included temperature sensor enables true room-by-room zoning
- Works with Alexa, Siri, Google Assistant, and Matter for maximum ecosystem flexibility
- No C-wire required in most homes, simplifying installation
Cons:- Highest price in this roundup even when discounted
- Wi-Fi dependency means lost smart features during outages
- Setup can feel complex for first-time smart thermostat buyers
Best for: Homeowners who want one high-impact upgrade that lowers energy bills and works with any voice assistant
Not ideal for: Renters, apartment dwellers without HVAC control, or buyers who only want to dip a toe into smart home tech
- Compatibility:Most 24V systems: gas, electric, oil, forced air, heat pump, radiant
- Display:60% larger than previous models
- Connectivity:Wi-Fi, Matter
- Voice Assistants:Alexa, Siri, Google Assistant
- Sensor Support:Nest Temperature Sensor (2nd gen), included
- Energy Savings:Up to 31% on heating and cooling
- Adaptive Eco:Yes
- Installation:No C-wire required in most homes
Our verdict“The discounted Nest Learning Thermostat is the single smartest smart-home purchase in this lineup for homeowners who will recoup the cost through energy savings.”
EIGHTREE Smart Plug WiFi Outlet Works with Alexa & Google Home, 15A, 4-Pack
If the Nest is the deep end of smart home ownership, this four-pack is the shallow end, and I mean that as a compliment. For the price of a takeout dinner, the EIGHTREE 4-Pack turns four ordinary devices into voice-controllable, schedulable smart devices. At a 15A / 1800W rating, each plug can handle demanding appliances, which is exactly where it beats the GHome Smart Plug Mini in this same roundup: the GHome tops out at 10A, so space heaters, coffee makers, and some power tools are off the menu for that cheaper option.
Setup is where EIGHTREE earns its reputation. Bluetooth auto-discovery in the Smart Life app means the plugs appear on your phone almost as soon as you plug them in, and from there linking to Alexa or Google Home takes a couple of minutes. That said, a common frustration deserves a flag: these plugs must be set up through the Smart Life app first, not discovered directly through the Alexa app, which trips up buyers who skip the manual. Once connected, scheduling, timers, and away-from-home remote control all work reliably.
Where it falls short of the Linkind Matter plug is ecosystem breadth and resilience. There is no Apple Home support, no Matter protocol, and no offline LAN communication, so if your internet drops, remote control drops with it. For Alexa and Google households, those limitations rarely matter day to day, which is why this four-pack sits second in my rankings: it is the best value-per-outlet deal here, and the discount goes further than with any other product listed.
Pros:- 15A / 1800W rating supports high-draw appliances like heaters and coffee makers
- Bluetooth auto-discovery makes first-time setup fast
- Scheduling, timers, and remote control from anywhere
- Compact housing fits snug outlets and power strips
Cons:- Setup must go through the Smart Life app rather than Alexa directly
- 2.4GHz Wi-Fi only
- No Matter or Apple Home support
Best for: Alexa or Google Home users who want the most smart outlets per dollar
Not ideal for: Apple Home users and anyone who wants their plugs to keep working during internet outages
- Current Rating:15A
- Voltage:120V
- Max Wattage:1800W
- Connectivity:Wi-Fi (2.4GHz)
- Compatible Platforms:Alexa, Google Assistant, SmartThings, iOS, Android
- Control Methods:App, voice, schedules, timers
- Quantity:4-pack
Our verdict“The best outlet-for-your-dollar deal in this lineup for Alexa and Google households that need plugs that can handle serious appliances.”
Amazon Smart Thermostat
Not everyone needs their thermostat to learn, and this model proves it. The Amazon Smart Thermostat covers the fundamentals with ENERGY STAR certification, schedule-based adjustments, presence detection that heats and cools only when you are home, and tight Alexa integration for routines and voice commands. At its frequent sale price, it is often less than a third of the Nest bundle’s cost, and that gap is the entire reason it exists in this lineup.
The honest comparison with the Nest Learning Thermostat comes down to autonomy. The Nest figures out your schedule on its own and supports add-on sensors for zoning; the Amazon expects you to set schedules yourself (or let Alexa hunches nudge you) and offers no room sensors at all. The display is also modest where the Nest’s is a design centerpiece. In exchange, you get guided DIY installation that is genuinely beginner-friendly, plus utility rebates in many regions that can knock the effective price down even further. For a rental property, a second home, or a first thermostat, those tradeoffs are easy to accept.
Two requirements deserve attention before you order. It needs a C-wire (or an adapter) to power it, so older homes without one should budget accordingly. And it has no far-field microphone, so voice control means speaking to a nearby Echo device rather than to the thermostat itself. Neither flaw is disqualifying at this price, but both explain why the Nest commands a premium.
Pros:- ENERGY STAR certified with real schedule and presence-based savings
- Guided DIY installation is approachable for beginners
- Frequently discounted, and utility rebates can lower the cost further
- Integrates cleanly with Alexa routines and the Alexa app
Cons:- Requires a C-wire or power adapter
- 2.4GHz Wi-Fi only
- No built-in microphone, so no direct voice control at the wall
Best for: Budget-conscious buyers and Alexa households who want thermostat savings without the premium price
Not ideal for: Homes without a C-wire and buyers who want self-programming or multi-room temperature sensing
- Dimensions:3.56 x 3.56 x 0.84 in
- Weight:3.86 oz
- Compatibility:Most 24V HVAC systems, C-wire required
- Connectivity:2.4 GHz, 802.11 b/g/n
- Certifications:ENERGY STAR, ECOLOGO Gold
- Voice Control:Alexa via Echo devices
- Model Number:S6ED3R
Our verdict“The smartest thermostat deal for Alexa households that want energy savings on a strict budget, provided a C-wire is already in place.”
Linkind Matter Smart Plug with Apple Home, Alexa, Siri, Google Home Compatibility
Discounted gear usually means compromised gear, but the Linkind Matter Smart Plug flips that assumption. Because it speaks the Matter protocol, one plug simultaneously appears in Apple Home, Alexa, Google Home, and SmartThings, with no ecosystem loyalty required. If you share a home with an iPhone user and an Android user, or you suspect your assistant preferences might change before your plugs do, this is the outlet that will not need replacing. That is a claim neither the EIGHTREE nor the GHome plugs can make.
The feature I would highlight above the rest is offline LAN communication. Most budget Wi-Fi plugs route every command through the cloud, so an internet outage means dead plugs. Matter lets these respond to local network commands even when the wider internet is down, which is the kind of reliability difference you do not appreciate until the day it saves you. Fire-resistant housing, FCC certification, and overload protection round out a safety story that matches the EIGHTREE plug watt for watt at 1800W.
The catch is setup friction and hub dependency. Full multi-platform integration requires a Matter-certified hub, which might be an Echo, a HomePod, or a Nest Hub, and buyers starting from zero will need to account for that. It also shares the 2.4GHz-only limitation of every plug here, and the per-plug price typically runs higher than the EIGHTREE four-pack. This option is better suited to buyers buying two or three plugs for a mixed-ecosystem home than to someone furnishing a whole house on a single discounted order.
Pros:- True Matter support across Apple Home, Alexa, Google Home, and SmartThings
- Offline LAN control keeps plugs working during internet outages
- 1800W / 15A capacity with overload protection and fire-resistant materials
- Clean setup through the Matter standard once a hub is present
Cons:- Requires a Matter-certified hub for full platform integration
- 2.4GHz Wi-Fi only
- Higher cost per plug than the EIGHTREE 4-Pack
Best for: Multi-platform households, especially Apple Home users, who want plugs that survive ecosystem changes
Not ideal for: Buyers without a Matter hub or anyone maximizing outlet count per dollar
- Power Capacity:1800W, 15A
- Protocol:Matter with LAN communication
- Wi-Fi:2.4GHz only
- Compatible Platforms:Apple Home, Alexa, Google Home, SmartThings, AiDot
- Safety:FCC certified, fire-resistant materials, overload protection
- Offline Control:Yes, via local LAN
Our verdict“The plug to buy if you want your discounted smart home to still fit your life when you switch phones, speakers, or assistants.”
GHome Smart Plug Mini, WiFi Outlet Compatible with Alexa and Google Home, Timer, APP Control, 4 Pack
Sometimes the right smart home purchase is the smallest one. The GHome Smart Plug Mini four-pack is the least expensive route in this entire roundup to a home that responds to voice commands, and for lamps, fans, humidifiers, and phone chargers, its compact 2 x 2 x 1 inch housing does the job without hogging the second outlet. ETL and FCC certifications mean the safety basics are covered, which is not guaranteed at this price tier.
Its limitations define its place in the rankings. The 10A rating is the headline restriction: compared with the EIGHTREE plugs at 15A, the GHome cannot safely run space heaters, large coffee makers, or anything approaching 1200W. Against the Linkind Matter plug, it lacks Matter support, Apple Home compatibility, and offline control, meaning it is a cloud-dependent device in an Alexa-or-Google household, full stop. Setup follows the familiar two-step pattern: register the plugs in the GHome app first, then link your assistant, and remember that only 2.4GHz networks are supported.
So why include it at all? Because the buyer it serves is real: someone who wants to try smart home automation for the price of a movie ticket before committing to thermostats or hubs. For dorm rooms, first apartments, holiday lighting, and hard-to-reach lamps on timers, this pick makes the most sense. Just treat it as a trial run, because if the smart home bug bites, you will likely graduate to the EIGHTREE or Linkind plugs for anything demanding.
Pros:- Lowest cost per outlet in this roundup
- Genuinely tiny housing leaves the second outlet free
- ETL and FCC certified for safety
- Scheduling, timers, and app control cover the basics well
Cons:- 10A rating limits use to low-wattage devices
- 2.4GHz Wi-Fi only, with no 5GHz support
- Setup must run through the GHome app before assistant linking
Best for: First-time buyers, students, and anyone automating low-power devices on the tightest possible budget
Not ideal for: Buyers running high-wattage appliances or anyone invested in the Apple Home ecosystem
- Amperage:10A
- Voltage:120V
- Dimensions:2 x 2 x 1 inches
- Connectivity:Wi-Fi, 2.4GHz only
- Compatible Assistants:Alexa, Google Home
- Certifications:ETL, FCC
- Quantity:4-pack
Our verdict“The cheapest legitimate way to start automating your home, as long as you keep it to lamps, fans, and other light-duty devices.”
How We Picked
Because every product here is being judged as a discounted device, I weighted value per dollar more heavily than raw feature counts. A plug that is 40% off but only works with one ecosystem is a worse deal than a full-price-looking plug that works with everything, and my rankings reflect that logic.
My selection criteria broke down into four factors. First, real discount potential: I favored devices that frequently sell below their list price and have a track record of sale pricing across major retailers. Second, ecosystem flexibility: Matter support and multi-assistant compatibility matter more in 2026 than ever, because nobody wants to rebuy their hardware when they switch phones or speakers. Third, setup friction: discounted gear is often a first smart home purchase, so I prioritized devices a beginner can install without an electrician or a computer science degree. Fourth, payback potential: for thermostats especially, I looked at energy savings claims and ENERGY STAR certification, since a thermostat that trims your utility bill is the rare gadget that earns its discount twice.
I also compared each product directly against the others in its category rather than against the market at large. The two thermostats are measured against each other, and the three plug multipacks are measured against each other, because those are the real decisions a discounted shopper faces at checkout.
Factors to Consider When Choosing Discounted Smart Home Devices
A discount only matters if the device fits your home. Before you buy any of the five products above, here is how I would think through the decision.Thermostat or Plug: Where Your Discount Goes Furthest
Thermostats and plugs solve different problems, and the smartest first purchase depends on your biggest annoyance. If your energy bills sting every month, a discounted thermostat like the Nest Learning Thermostat or Amazon Smart Thermostat attacks that cost directly, with savings that compound for years. If your annoyance is walking across the room to turn off lamps, or forgetting whether you left the iron plugged in, a $20 plug solves it instantly. My general rule: homeowners with high HVAC usage should buy the thermostat first; renters and apartment dwellers should start with plugs and skip thermostats entirely unless they control their own heating.
The 2.4GHz Question
Every plug in this roundup, and the Amazon Smart Thermostat besides, connects only to 2.4GHz Wi-Fi. This is the single most common cause of setup frustration with discounted smart devices. Most modern routers broadcast both bands under one network name, and some phones default to 5GHz during setup, which makes the device appear dead or undiscoverable. Before buying, check your router settings: you may need to temporarily split your bands or connect your phone to the 2.4GHz network during pairing. This is not a defect in any of these products, but it is a hurdle worth anticipating.
Why Matter Matters in 2026
Matter is the industry standard that lets one device work across Apple Home, Alexa, Google Home, and SmartThings at the same time. The Linkind plug is the only product in this lineup with full Matter support, and that matters most for two kinds of buyers: mixed households where not everyone uses the same phone ecosystem, and anyone who has switched (or might switch) voice assistants and does not want to rebuy hardware. If you are confidently an Alexa-only or Google-only household and plan to stay that way, the cheaper non-Matter plugs like the EIGHTREE will serve you just as well for less money.
Amperage and What You Can Actually Plug In
Plug ratings are not fine print, they are the difference between a working smart home and a tripped breaker. The EIGHTREE and Linkind plugs handle 15A / 1800W, which covers space heaters, coffee makers, microwaves, and most kitchen appliances. The GHome Mini tops out at 10A, making it suitable only for lamps, fans, chargers, and similar light loads. Overloading a lower-rated plug is a genuine fire risk, not a theoretical one, so match the device to the plug rather than assuming all smart outlets are interchangeable. When in doubt, check the wattage printed on the appliance you plan to automate.
The C-Wire Check for Thermostats
If you are leaning toward a thermostat, find out whether your home has a C-wire (common wire) before ordering. The Amazon Smart Thermostat requires one, or a power adapter that adds cost and complexity. The Nest Learning Thermostat notably works in most homes without one, which quietly offsets part of its higher price by avoiding an electrician visit. The wire is usually blue and sits behind your current thermostat; a two-minute look, or a photo sent to your utility company, can confirm what you have. Skipping this check is the most common thermostat-buying mistake I see.
Frequently Asked Questions
Is it better to buy a discounted smart thermostat or several smart plugs first?
It depends on where your money leaks. A thermostat like the Nest Learning Thermostat can cut heating and cooling costs by up to 31%, so for homeowners in climates with real winters or heavy summer cooling, it typically pays for itself within a few years and is the stronger long-term investment. Smart plugs, on the other hand, cost a fraction of the price, install in minutes, and are better suited to renters or anyone who wants to eliminate small daily annoyances like lamps and fans left running. If you own your home and pay the utility bills, I would buy the thermostat first and add plugs later. If you rent or share costs, start with a four-pack of plugs and skip the wiring entirely.
Why do all these discounted smart plugs only support 2.4GHz Wi-Fi?
2.4GHz is cheaper for manufacturers to implement and technically better for smart home use, because the lower frequency travels farther and penetrates walls more reliably than 5GHz, which suits devices that sit in basements, garages, and far corners of the house. The tradeoff is bandwidth, but a smart plug sends almost no data, so speed is irrelevant. The practical problem is setup: many modern routers combine both bands under one network name, and phones often connect at 5GHz during pairing, which prevents the plug from being found. Splitting your bands into separate network names, or forcing your phone onto 2.4GHz during setup, resolves nearly every connection issue with these devices.
Do I really need a Matter-compatible smart plug like the Linkind?
Only if your household mixes ecosystems or you expect your preferences to change. Matter lets a single plug work natively in Apple Home, Alexa, Google Home, and SmartThings, and it enables local control that keeps working when your internet goes down. If everyone in your home uses Alexa speakers and Android phones and has for years, the EIGHTREE or GHome plugs will behave identically for everyday tasks at a lower price per outlet. But if one partner uses an iPhone with Apple Home, or you have thought about switching assistants, buying Matter-compatible plugs now spares you from rebuying every outlet later, which is where the Linkind’s slightly higher cost earns its keep.
What happens to these devices when the Wi-Fi or internet goes down?
Every product here continues to function manually at its most basic level: plugs still work as physical on/off switches, and thermostats keep controlling temperature with their last settings. What you lose during an outage is remote control, scheduling, and voice commands for anything that depends on the cloud. The exception is the Linkind Matter plug, which supports offline LAN communication, so local voice commands and automations keep working on your home network even without internet. If reliability during outages matters to you, because of a medical device, a freezer, or an aquarium, that offline capability is a meaningful reason to choose Matter over the cheaper cloud-dependent plugs.
Can I install the Amazon Smart Thermostat or Nest thermostat myself without an electrician?
Most homeowners can, with one caveat each. The Nest Learning Thermostat does not require a C-wire in most homes and includes guided installation, so a confident DIYer with standard 24V HVAC systems usually finishes in under an hour. The Amazon Smart Thermostat also has excellent guided setup in the Alexa app, but it requires a C-wire or a power adapter, so older homes without that wire either need the adapter (a modest added cost) or professional help. In both cases, the process involves turning off power at the breaker, photographing the existing wiring, and connecting a handful of low-voltage wires. If your system is unusual, such as a high-voltage baseboard heater or a proprietary thermostat, have a professional assess compatibility before you buy.
Conclusion
After comparing all five, the right discounted smart home device comes down to what kind of buyer you are. Homeowners planning to stay put should put their discount budget toward the Nest Learning Thermostat (4th gen) bundle, because its energy savings and room-sensor zoning deliver value long after the sale price is forgotten. Budget-focused Alexa households with a C-wire already in the wall get the better bargain with the Amazon Smart Thermostat, which covers the essentials for a fraction of the Nest’s cost.
On the plug side, the choice splits three ways. Alexa and Google users buying in bulk should grab the EIGHTREE 4-Pack for its 15A rating and outstanding cost per outlet. Multi-platform households and Apple Home users should spend a little more on the Linkind Matter plug, since its cross-ecosystem support and offline control protect the investment. And first-time buyers, students, and renters automating lamps and fans should feel no guilt choosing the GHome Smart Plug Mini as a low-risk trial run. Whichever route you take, check your Wi-Fi band, your C-wire situation, and your appliance wattage first, and the discount will feel like a smart decision rather than a lucky one.
