I have (3) HVAC Controllers that I am using. They were running (3) WIRELESS remote temp sensors.
I recently switched to flush mount WIRED temp sensors and they are working great.

I would like to use the WIRELESS remote temp sensors in some other rooms and my rack closet to get temps that I can display on my automation system.
I tried to set up phantom version of the HVAC Controllers in the programming. It let me attach the WIRELESS remote temp sensors but would not get me any temps (Displays 72 no matter the actual temp).

Does it require an actual HVAC Controller to work?

Any ideas to make use of these WIRELESS remote temp sensors in RR2?
