You don’t think about your thermostat until it sticks out like a sore thumb on the wall, or worse, until a toddler decides it’s a toy. Whether you’re covering a scuff left by an old unit, building a multi-room sensor network, or guarding settings from curious hands, the right accessories turn a Nest install into a finished room. This list walks through wall plates, trim kits, sensors, and protective covers that solve those everyday frustrations. You’ll see which extras genuinely fit your thermostat model, and which ones to leave on the shelf.

elago Wall Plate Cover Plus for Nest Thermostat 2020
Meet The Standout Selections
Swapping an old thermostat for the Nest 2020 almost always leaves a paint scar on the wall. This elago plate solves that by sitting behind the new unit and covering blemishes up to several inches wide. The two-pack format suits anyone installing in more than one room, or anyone who wants a spare tucked away for future color changes.
It’s worth noting that the design is circular and purpose-built, so it complements the 2020 model’s footprint. For shoppers who want one plate per thermostat without leftovers, the single-plate Plus version appears later in this list.
Positive Points
- In-house design keeps tolerances tight, so the Nest sits flush without wobble
- Two-plate value suits multi-room homes or staged renovations
- Circular shape mirrors the thermostat, creating a clean built-in look
- Hides paint mismatches and old mounting holes without spackle work
Things To Consider
- Available colorways are limited compared to elago’s other lines
- Won’t fit the older Nest Learning Thermostat models covered by item 7
Feature Snapshot
Best Suited To
Anyone upgrading two or more rooms to the Nest 2020 at once and wanting a seamless wall finish.
Skip It When
You only need a single plate and prefer the slightly broader color range of the single-pack Plus version covered later in this list.
When in doubt about fit, first-party accessories tend to be the safest call. This official Google trim kit is made for the Nest Thermostat specifically, so alignment with the thermostat body is precise. The Charcoal colorway blends with darker walls and deeper-toned decor without drawing the eye away from the display.
Owners commonly reach for this kit right after removing a wider legacy thermostat, since trim plates (also called wall plates) are designed to mask gaps that would otherwise require repainting. It also doubles as a clean install for new construction where the existing hole is just a bit too small.
Real-World Strengths
- First-party build ensures flush alignment with Nest Thermostat edges
- Charcoal finish hides minor dust and fingerprints over time
- Streamlines the install when swapping from any older thermostat footprint
Worth Noting
- Limited to one color option in this listing
- Slightly thicker profile than aftermarket minimalist plates
- Won’t fit Nest Learning Thermostat models, which use a different footprint
Made For
Shoppers who want a guaranteed fit from Google’s own accessory line and prefer dark-toned finishes.
Consider Something Else When
You want a brighter, white-on-white look, in which case the Petrichor Snow plate reviewed next may suit better.
Light walls tend to clash with charcoal or gray trim plates, which is where this Snow-finished option earns its place. Petrichor markets the plate as a quick way to add a uniform splash of color around the Nest’s surroundings. Installation is described as easy, which fits anyone who wants a no-drill, no-paint solution.
Compared with the elago designs reviewed earlier, this plate takes a different design route and emphasizes bright-white modern interiors. For most homeowners with white walls, the visual difference between the thermostat body and a darker plate can feel jarring, so a Snow finish solves that without much fuss.
Standout Benefits
- Bright Snow finish complements white or pastel walls
- Designed for the 2020 Nest model, so no trimming is needed
- Modern look ties thermostat into minimalist interiors
Trade Offs
- White finish shows dust and scuffs more visibly than darker plates
- Single colorway in this listing limits matching flexibility
Quick Facts
Best Suited To
Anyone with light-toned walls who wants a near-invisible frame around the 2020 Nest.
Look Elsewhere When
You prefer a darker accent, in which case the Google Charcoal trim kit two reviews up is the closer match.
This bundle pairs the Nest Thermostat itself with the trim plate and a steel mounting plate, which simplifies a first-time install. The included steel plate matters for houses with electrical boxes behind the wall opening, an issue the trim-only kits reviewed earlier don’t address. The Snow finish matches the standalone Petrichor plate visually, so the bundle doubles as a clean color choice.
The thermostat itself supports scheduling through the Google Home app and includes a built-in away mode that lowers heating or cooling when nobody’s home. For households that want one order to cover the wall fix and the device, this bundle removes guesswork.
Strengths Worth Knowing
- Includes the steel mounting plate for electrical-box installs
- Bundled trim and thermostat match in color from the start
- App-based scheduling reduces fiddling at the wall unit
- Away-mode feature lowers energy use in empty homes
Room For Improvement
- Bundle pricing runs higher than buying trim alone
- Snow finish may show wall dust more visibly over time
Perfect Match For
First-time Nest buyers who need the thermostat, the trim, and an electrical-box plate in a single package.
A Better Fit Elsewhere
If you already own a Nest and just need a cover, the elago Plus 2 two-pack back at item 1 saves money.
Most thermostats only read the room they’re mounted in, which is rarely the room where you actually spend time. The Nest Temperature Sensor changes that by reporting conditions from wherever you place it, whether that’s a nursery, a home office, or a basement living room. The three-pack format covers a whole floor without buying extras later.
Sensors pair with compatible Nest thermostats over low-energy Bluetooth up to roughly 50 feet away, giving most homes reliable coverage. Putting different sensors in different rooms lets you prioritize comfort in the spaces that matter most, rather than chasing the hallway reading.
Practical Pluses
- Three sensors handle typical multi-room homes in one order
- Prioritizes comfort in nurseries, offices, and bonus rooms
- Wireless placement avoids drilling into walls
- Compatible with both Nest Learning Thermostat and Nest Thermostat E
Points To Keep In Mind
- Bluetooth range can drop through thick walls or metal framing
- Not every Nest generation supports sensors, so check compatibility first
Feature Card
Built With In Mind
Two-story homes where the upstairs nursery runs hot and the downstairs bedroom runs cold.
Reach For A Different Pick When
You don’t yet own a Nest thermostat, in which case the bundle at item 4 is the smarter first purchase.
A thermostat guard isn’t decorative, it’s defensive. The Honeywell Home CG511A1000 puts a clear plastic shell over the unit with a key lock to keep curious fingers from changing settings. That matters in offices, classrooms, and rental properties where constant adjustments drive energy bills up.
It’s sized for thermostats up to about 5 inches tall by 6 inches wide, which covers most residential models including many Nest installs. The clear casing keeps the display visible for daily monitoring while locking the controls underneath. Compare that to the trim plates reviewed earlier, which serve a purely cosmetic role.
Everyday Advantages
- Key lock prevents unauthorized schedule changes
- Clear casing keeps display visible at a glance
- Fits common Honeywell and third-party residential models
Minor Gripes
- Bulkier than trim plates and visually industrial
- Requires a screwdriver for mounting
Who It Suits Best
Property managers and homeowners with kids who treat wall controls like toys.
Not Your Match When
You’re after a decorative trim upgrade, where the elago Plus 2 plate at item 1 fits the brief better.
The Learning Thermostat has a different footprint than the 2020 model, and that’s exactly where this elago plate is built to fit. The Chrome Bronze finish adds a warm metallic accent that suits rooms with wood tones, brass hardware, or earthy palettes. Owners of older Nest hardware finally get a color option beyond plain white or black.
Unlike the elago plate at item 1, this version is designed to follow the curve of the Learning Thermostat’s body, so it reads as a natural extension rather than a flat ring. The trade-off is generation-specific compatibility, which means it won’t swap onto a 2020 Nest without adaptation.
Notable Upsides
- Chrome Bronze finish warms up neutral interiors
- Curved profile matches the Learning Thermostat body
- Covers old screw holes and paint imperfections
Softer Spots
- Generation-locked to Learning Thermostat 1st/2nd/3rd
- Metallic finish may not match matte modern interiors
Right Fit For
Nest Learning Thermostat owners who want a decorative upgrade instead of a plain white plate.
Swap It Out When
You have the newer 2020 Nest, in which case the elago Plus 2 at item 1 is the compatible match.
Metal wall plates bring a different weight and feel than plastic trim, which matters in rooms where the thermostat sits next to other metal finishes. The POPMAS plate is matched to the dimensions of the Nest Learning Thermostat across 1st, 2nd, and 3rd generations, with explicit model numbers listed for cross-checking. The Silver finish pairs well with stainless appliances and modern hardware.
The brand is clear about what it doesn’t fit: the 2020 Nest and the T3018US learning model. So you should measure or confirm the model number before ordering. Once confirmed, the install is straightforward and the metal plate tends to feel more rigid during handling than plastic alternatives.
What Earns Its Place
- Metal construction feels sturdier than plastic plates
- Silver finish blends with stainless kitchens and modern hardware
- Works across three Learning Thermostat generations
Honest Caveats
- Not compatible with the 2020 Nest Thermostat or T3018US learning model
- Requires careful model verification before ordering
Whose Shelf It Belongs On
Learning Thermostat owners in modern homes who want the durability of metal at a friendly price.
Another Choice May Suit When
Your thermostat is the 2020 Nest, where the elago Plus 2 at item 1 is the proper fit.
The Gedreew lock box is a step up from the Honeywell guard reviewed earlier, mainly because it uses a key instead of a simple latch. For landlords managing short-term rentals, that distinction matters: a determined tenant can defeat a press-fit guard, but a keyed lock adds real friction. The clear PC plastic lets you check the current temperature without unlocking.
The unit fits thermostats up to about 5 inches tall by 6 inches wide, which covers most residential units. PC (polycarbonate) is a tough, shatter-resistant plastic often used in safety glasses, so daily bumps and key scratches are less likely to cloud the view over time.
Useful Strengths
- Key lock resists tampering better than press-on guards
- Clear polycarbonate keeps the display fully visible
- Compatible with Honeywell Home thermostats and similar sizes
A Few Limitations
- Bulkier than cosmetic trim plates
- Key management required, lose it and access is harder
- Not designed for sleeker Learning Thermostat aesthetics
Who Should Grab It
Landlords and Airbnb hosts who need tamper resistance plus visible readouts for tenants.
Where A Sibling Pick Shines
Homeowners wanting a low-profile aesthetic should look at the elago Chrome Bronze plate at item 7 instead.
Not every install needs a two-pack. This single-plate version of the elago design is built from double-coated polycarbonate, a durable plastic that resists cracking and fading better than standard ABS. For one-room installs where you only need one trim plate, this is the simpler order without leftover hardware.
Compared with the two-pack at item 1, you’re trading extra inventory for a leaner purchase. The double coating matters most in sunlit hallways where cheaper plates can yellow over time. If your wall catches direct afternoon light, the coating is a meaningful upgrade even at single-plate quantity.
What It Does Well
- Polycarbonate build resists yellowing from UV exposure
- Double-coated finish extends visual lifespan
- Single-plate format suits solo thermostat swaps
Potential Drawbacks
- Color may appear slightly different than screen previews
- Single quantity means no spare for future rooms
Made For
Homeowners replacing one thermostat and wanting a UV-resistant finish in a sunlit hallway.
Consider Something Else When
You’re upgrading multiple rooms, where the elago two-pack at item 1 offers better per-plate value.
Choosing Trim Kits, Sensors, and Covers That Fit
Start With Your Thermostat Generation
Every wall plate, trim kit, and sensor in this list targets a specific Nest model, so model number matters more than aesthetics. The 2020 Nest Thermostat, the Nest Learning Thermostat (1st through 3rd generation), and the Nest Thermostat E each use different footprints. Measure your current base or check the model on the back before ordering, since a beautiful plate that doesn’t fit the cutout is just expensive wall art.
Match the Plate to the Wall Condition
Cosmetic plates like trim kits and wall covers are sized to hide old mounting holes and paint scars. If your previous thermostat left a large rectangular outline, you’ll want a plate with generous coverage, which is one reason these elago and Petrichor options exist. For cleaner walls, a slimmer first-party trim from Google may be enough.
Decide Between Sensors and Locks
Comfort upgrades and security upgrades serve different goals. Nest Temperature Sensors solve the “thermostat is in the hallway” problem by reporting conditions from the rooms you actually use. Lock boxes like the Honeywell guard and Gedreew key lock solve the opposite problem: keeping settings exactly as you left them. Pick the one that matches your daily frustration.
Think About Color and Finish Over Time
White plates disappear against light walls but show dust and scuffs faster. Charcoal plates hide grime but feel heavy against airy palettes. Metallic finishes like Chrome Bronze or Silver add warmth or modernity, but only when the surrounding hardware already leans that direction. Choosing a finish that complements nearby fixtures makes the thermostat feel intentional instead of added on.
Key Considerations Across These Picks
Where Shoppers Go Wrong
The most common mistake is buying a plate based on the Nest name alone, without checking the generation. The 2020 Nest, the Learning Thermostat, and the Thermostat E each take different cutouts, so a plate that fits one may not seat flush on another. Measure the existing base, confirm the model number, and only then order. Skipping that step often means a return trip.
What Separates Premium From Basic
Higher-tier picks in this category tend to use better materials: polycarbonate instead of basic plastic, double coatings to resist UV yellowing, or metal bodies for rigidity. Those upgrades show up over years of use, not minutes after install. Spending more makes sense when the thermostat sits in direct sunlight, in a high-traffic hallway, or in a room where aesthetics carry weight. For a guest room thermostat that rarely gets touched, a basic plastic plate is plenty.
