Heater tEmperature resets to 100 °C on every reboot

buliwyf42 commented 7 months ago

Describe the bug

I use a Heater with a shelly Plug to heat water. Unfortunately if i set a Temperature the Temp is reseted after every reboot. Previously this could be set with min and max soc. The Option for "PLAN" like on my go-e charger is not shown for the heater. Perhaps i just f.. some config but setting a Limit should survive a restart.

Steps to reproduce

Restart EVCC
Set Temp
Restart
Set Temp again.

No idea, why "PLAN" isn´t shown within the loadpoint. Normally it is only unvisible if heating: true is configured. You can set vehicle limitSoc also via API https://docs.evcc.io/docs/reference/api#vehicles

Sorry, I mixed up the copy and paste. The Charger is configured heating: true. Therefore, "plan" should not appear? Is there any other Way to configure if heating: true? If I remove heating: true i'm back to 5% steps which is not fine enough.

Yes.

Is there any other Way to configure if heating: true?

You can set it via REST API in 1% steps. (see link above)

@naltatis why should planner be hidden for heating devices? Seems hot water in the morning could be nice?

VolkerK62 commented 7 months ago

Problem seems to be, to define the needed energy.

Edit: see https://github.com/evcc-io/evcc/pull/9393

naltatis commented 7 months ago

Yes, energy does not correlate linearly to temperature increase and we don't have charging sessions. Means our resetting mechanism don't work here.

OT physically it should. But we sre missing a battery capacity here.

Seems this is more a discussion now?
