I have my Homematic IP thermostat heads Evo connected to Home Assistant/Raspberry Pi and they work perfectly there. However, when I connect them to Homey, I only get the room temperature reading and can’t control the temperature, so I can’t integrate the thermostat heads into a flow. Has anyone else experienced this problem and found a solution?

You most probably use the “official” app?

I can recommend the [Home Assistant community app](https://community.homey.app/t/71477) for 100%. I’m using it since the early test releases.

In case you miss an entity, you can add it afterwards! Even entities from other devices!  
Example:

> [@\[APP\]\[Pro\] Home Assistant - Community App](https://community.homey.app/t/app-pro-home-assistant-community-app/71477/1388):
>
> Mobile: Go to device settings, Maintenance \> Try to Repair Web: Right click \> Repair Next, Add entity Now enter a part of the name of temperature entity, or the type; “target” should get you results. When you notice the desired entity, select it Next, adjust the proposed Homey capability; erase it and enter “target” or “temp”. Now the target\_temperature shows \> select it …

Two counter-questions:

1. Why did you format the text as “Perfomatted text”?
2. How and/or with which app did you connect your thermostats to Homey?  
– With the Homey [Home Assistant](https://homey.app/a/io.home-assistant/) App?  
– With the Homey [Home Assistant Community](https://homey.app/a/io.home-assistant.community/) App?  
– Via MQTT?  
– In a completely different way?

Hello Dirk,

A thermostat in HA is using the climate domain (al least it should).

Can you please check in HA, which entities are used for the HA device? If there is a climate.xxx, then add a climate device usong the HA community app and search for this entity.
