is there someone who have the solution with Fibaro HC2 in combination with Nest thermostate?


Is it compatible with multiple Nest thermostats in the same house and linked to the same account?


I haven't tested it with multiple thermostats, but normally it should work. It will create a widget for each thermostat in the same account. If there is a bug, let me know so I can fix it.


I have followed all the steps and the 3 thermostats that I have associated in the same account have been created correctly. The only problem I see is that in the preview of each one they appear without buttons to adjust the mode (ECO/Manual/...) or the temperature. The rest of the information (temperature, humidity and the icon is green with the temperature and the activated mode) are working correctly. I deleted everything and started again twice in case it was an authentication problem but I still don't see any buttons to adjust the thermostats.


Are you using the web interface or Android or iPhone ? On the web interface, you need to click on the eye at the top right of the thermostat icon in order to open a panel at the right. The control buttons are in this panel.
