You need a measure\_temperature and a target\_temperature for this UI element. One for current and one for target temperature. ---

Yes, I know. But are struggling how to merge both into one capability. Still getting errors. ---

Why one capability? You need both capabilities in one device. ---

They are automatically merged in 1 GUI element if the device’s class is `thermostat`, no need for a capability.json for this. Might be that there are more classes now, as many have been added lately, but only know of thermostat currently. ---

Just add both capabilities to your driver.json > target\_temperature has ui component thermostat assigned. ![Screenshot_20241222_224639_Firefox](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/1/f148e873589d01e68b5bbb0fc3201b1c0779b582.jpeg) > **[Tutorial: Device Capabilities - Homey Apps SDK v3](https://apps-sdk-v3.developer.homey.app/tutorial-device-capabilities.html)** ---

thanks, this helped! now i have both values shown in UI thermostat i only have struggles with the value that target\_temperature shows me. I can adjust setting but after that the UI reset to maximum value. Can i change that behavior somewhere? i’am reading the value and see in log it’s the right value solved!!
