Load management grid meter time out failed #14248

Closed Lightmanster closed 5 months ago

Lightmanster commented 5 months ago

Describe the bug

Set EVCC in Fast mode. Car connected , will charge with 3x 16A. If Grid meter input failed, (connection lost in my test case) evcc will continue with current load. (3x 16A). Normal behaviour without evcc and Loadbalance at Alfen charger is after 1 minute no data it will failback to min load of 6 A to prevent overload of main circuit.

EVCC still communicate with alfen LP even without grid meter input, so LP will not go in failback minimum load.

Preferable is a timeout (60s) in gridmeter for incorrect or no data input. After 60 s tell LP to go to minimum load of 6 A.

Steps to reproduce

  1. Do a charge session full load 3x 16A
  2. disconnect grid meter
  3. Load continue with 3x 16A also when grid is overloaded ...

That's a very good point. Imho we should treat any circuit as overloaded if we don't have measurements.

/cc @premultiply my idea would be to set as-is values to math.Inf() or any other high value after defined timeout which will in turn treat a circuit as overloaded?
