Hi, I have ELKO ESH Super TR RF PH - Thermostat i my house for controlling my floor heating. This is a zigbee device. It is no problem to enter it into Homey and it should be a supported device. But after some time all me devices are lost and disconnected. I loose all my flows and I have to re-install the devices. This has happened several times now, and it’s becoming a big problem. Anyone that have the same problem? Any solution or fix to this?
