If the KE110 could also connect to switches and Plugs, it could be used to control room heaters, dehumidifiers or indeed complete heating systems.

Obviously this could be achieved with rules/automation, but the KE110 has buttons which would make it much easier for those without the app!

The KE110 is just like the T315 temperature display, but with 3 buttons (Temperature up, Temperature down, On/Off) which is a very convenient way to control the KE100 radiator thermostat, but it could do so much more with the buttons and potentially replace house thermostats altogether, it just needs to be allowed to do so in the App!
