    Room sensors, one in the box, let it hold a chosen room at a set temperature or average several, and the display adds detail as someone walks closer. Matter brings it into Apple Home, but only mode and temperature can be changed there.
    What people praise
    • Room sensors can average temperatures across rooms
    • Display shows more detail as you walk closer

    Why it ranks
    Push-in wire clips keep a do-it-yourself install simple, and once connected the heating can be checked and adjusted from a phone or by voice through Alexa, Google Assistant or Siri. Homes without a C-wire need a power extender kit or a new wire run, adding cost and work.
    What people praise
    • Push-in clips make connecting wires simple
    • Heating can be monitored and controlled from a phone
    • Works with Alexa, Google Assistant and Apple HomeKit

How this list is ranked

Back to top
Who is eligible
Every smart thermostat in our reviewed catalogue is included, wall and radiator models alike. Second listings of the same thermostat are left out. The list opens on current models, those released in the last 2½ years (since Apr 2024); choose Include older models under Models to list them too. A product without a release date on record is always listed.
How they are ordered
By default, products are ordered by Ranking Net Score: points from reviews and discussions plus points from votes on BettaScore. Ties go to the product with more sources. Filtering or sorting renumbers the results from No. 1. Products without scored evidence stay Unranked and are not numbered.
Where the evidence comes from
18 public review sources across the matching products. Select a review topic on any card to see the quotes behind its points.
When it changes
The product list and review scores change only when we publish a reviewed update. Signed-in visitors can vote on each review topic (open a topic on a card): every vote adds or takes 0.1 points from that topic and from the Ranking Net Score straight away, and the order follows on the next page load. Votes are stored apart from review evidence, so they carry over between updates. Review evidence is from October 5, 2026.
Who pays for it
Nobody. BettaScore does not accept payment for placement. Each card shows review points and topic-vote points separately, even though their sum sets the default order.

What to look for in a smart thermostat

Back to top

Start with compatibility: your heating and cooling system, whether you have a C-wire, and the smart home system you use. Radiator thermostats fit a different setup from wall thermostats.

Then compare what the evidence says about installation, scheduling and automation, the app, and energy savings.

Questions to take to every card on this page

  • Does it work with your heating and cooling system and wiring?
  • Can you install it yourself?
  • Do the scheduling and automation fit how you live?
  • Does it work with your smart home system?

Frequently asked questions

Back to top
What does this smart thermostat list cover?
All reviewed smart thermostats in our catalogue. Products with scored review evidence get a rank; the rest stay on the list, marked Unranked.
How is the default order calculated?
Ranking Net Score adds points from reviews and discussions to points from BettaScore votes, and each card shows both parts. A vote counts right away: it updates the card and can move the product in the list.
How do filters and sorting affect rank?
They apply to the whole list and renumber the results: scored matches start from No. 1, and products without scored review evidence stay Unranked. Filtering and sorting never change a product's review or vote points.
Why are some specifications missing?
BettaScore shows only the facts it has on record. An unknown value is not treated as No, and we never fill a missing specification or evidence section with a made-up claim.
Where do the Type, Works with, heating & cooling and C-wire filters come from?
From each maker's own product, compatibility and support pages, checked thermostat by thermostat, not from whether a review happened to mention them. A platform or system the maker does not name is simply not listed for that thermostat.
