I have 3 door sensors (z-wave plus, version 1, not the version 2) all working fine temperature sensing wise with the latest fibaro app.
a lot of fibaro devices have different ways to let it send it’s NIF, what they also call the “inclusion/exlusion” command to the controller, 1 TMP button pushed in, and trippel pressing the other is just one of them, and in my mind the easiest to do and explain, as it is the same for all 3 versions.
So please tell what version of the device you really have, which fibaro app version and which Homey version, trying to install it by selecting a different device in homey will do 0,0, as it will select the correct driver during the pairing based on 3 unique ID’s, so even if you select a completely different brand’s device, the right fibaro driver will be selected by Homey for that device.
Not telling which device you have is just making the hay stack bigger where we need to find the needle in.
As there are 3 big differences of door/window sensors, it is just impossible to help.
And be REALLY SURE that you connected it properly, a loose connection, or a wire on the wrong spot is enough to let the door sensor say “i have no temperature sensor” which it will not change unles you factory reset it, and reinclude it into Homey.
And if you want to see more debugging, in the developer tools there is the Z-Wave Log, which you can enable, and see if there come in temperature values at all, all this could help to find the cause.
