I have finished my solar batter heater design and it's been running for several days now. The only issue I see is the offset.
I've tried various values and none seem to make any difference... so I just set the temp 2-3 degrees above where I want it. So strange.
I have 2 sensors, a probe that always works but isn't exact and the actual BMS temp as a primary. if the BMS temp becomes unavailable (Solar Assistant Pi crashes, HA crashes,etc), the probe temp is used instead. Everything is contained within the esp and ESPHome.

overall I'm very happy with the results!
