Hi RoganDawes
Thanks for awesome detailed explanation. It is adding alot of value!
I am embarking the home automation route and was thinking along the lines:
1) install the geyserwise thermostat
2) use an ESP32 to read the temperature from the thermostat - link this into HA (home assistant)
3) implement a smartswitch rated for use on a geyser (e.g. Sonoff POWR320D) to complement the existing manual isolator
4) implement the temperature and power logic in HA automation to switch the geyser on and off via the smartswitch
5) for safety set the thermostat manual cut out temp lower to 65deg (I have not used the geyserwise thermostat before, can the manual cut out temp be changed? )
This is very similar to OP design but the smartswitch does not integrate directly to the temp sensor and thus all intelligence moves to HA. It would be quite easy then in HA to adjust the temperature changes for summer and winter, also more control when not having much solar capacity or higer loads, etc.
Any other thoughts?
