I was thinking of building an interface but decided to try and save some time and bought this one
which took almost a week to arrive and is working fine with no problems.
My cylinder thermostat already uses low voltage to a relay which then provides DHW/ON/OFF mains voltage signals to the 3 port valve etc.
I should easily be able to use that low voltage to signal the hot water state to the raspberry pi and have it issue the required ebus commands at intervals.
Changing FlowsetHcMax to the required temp looks like the most likely solution at the moment.
Getting ebusd running on the pi and learning how to use it is an ongoing learning experience.
