Sleep? Can you eat that?
The external room temperature is by design only meant for direct association, so a temperature measuring zwave device directly sending the value to the valve.
(And then the value of measured temperature of the valve itself should be hidden in the GUI, though that is not possible in homey unfortunately)
But as homey is capable of receiving so many more types of temperature receiving devices (zigbee, wifi, Bluetooth) I’ve added a way to “simulate” this direct association inside the app (in the form of this flow card).
Though this external temperature (doesn’t matter in what way it is being send to the device) is just not possible to be read out from the valve for some reason, this is a limitation of the valve itself and is not something homey (or athom) can change.
I could add internally, that the value that is being send via the flow card is then also the value of the measured temperature shown in the GUI (not something I thought of right away, but is also a bit of a placebo effect) though that still wouldn’t catch if an direct associated sensor would send that value either.
