Ecobee3 Wi-Fi Smart Thermostat, HomeKit-enabled review:

28th November 2015 - CNET

Toronto-based Ecobee may not have the name recognition of Honeywell or Nest, but it was actually the first company to come out with an app-enabled thermostat. Its initial line of smart thermostats was funneled through dealers though, which limited the...

The state of the Apple HomeKit market: Apple's smart-home ecosystem has yet to coalesce

6th February 2017 - TechHive

While HomeKit is built into iOS and the fourth-generation Apple TV, which can act as a hub of sorts, macOS doesn't include it. And third parties are making HomeKit-enabled hardware, but not enough and in enough variety that if you're looking to equip...

Ecobee3 continues the trend of innovative and unique solutions for smart temperature control

The addition of remote sensors makes the ecobee3 ideal for dealing with a house with distinct hot and cold spots. This provides great additional functionality but without independent heating zones provides little benefits. The sharp touchscreen interface and ease of use are also noteworthy.

  • Use of remote sensors
  • Easy set-up and installation (provided you have a C-wire)
  • Sharp touchscreen interface
  • Excellent data tracking and reporting
  • Complex installation
  • Remote sensors can be configured only at the thermostat, not via the app
  • Geofencing depends on an IFTTT channel
  • Expensive

  1. a great bit of kit. but lets be clear ecobee do not manufacture for the uk market as the product runs on 24 volt AC. uk heating systems run on mains of nominal 230 volts AC. therefore you need to build a small power supply with transformer 230/24vac, 6VA is sufficient. also a 24vac slave relay with coil suppression is needed. the connection diagram can be found on the ecobee website. my system is Y-plan so i mounted parts in a box next to the 10 way terminal box in the airing cupboard. however PLEASE don’t attempt to do this if you don’t know what your doing – i am an electrical engineer. finally was disappointed with ecobee CHAT and SUPPORT via email who couldn’t answer loading requirements on the W1 output to the relay coil required to start the boiler. the 24 vac connects to Rh and C. good luck – its a bit tricky.
