Has anyone ever reverse engineered the comms protocol of the Geyserwise devices?
I would like to use it as a base for an automated thermostat. Hardware is great, but it would be even better if I could use it directly.
From what I can see, it seems to be a 2400 baud serial protocol (or possibly 1200 baud RZ protocol, given the odd bit patterns). But I can not see any correlations in the packets when I change temp, or press buttons…
If anybody has any previous attempts (even partial) to work from, that would be a great help!
