Through reverse engineering I was able to decode the protocol used to transmit temperature to a main zone input on the Elk M1 control. This will ONLY work on a main zone and NOT on an input expander. This is by design on the Elk itself.
So here it is. Manchester encoded:
· 3 start bits of ‘1’
· 8 data bits –...
