Storage remote charge limit resets randomly

[J1Buskens]

When I set the storage remote charge limit to 1kW (default 5kW) it remains there a few hours, but then at a random time reverts back to 5kW.

I'm seeing the same behavior. I think we need a service that we can call to send the "Remote Storage settings" to the battery within the "Remote Command Timeout".

Another solution would be to periodically change the "Remote Charge Limit" with 1 watt difference within the "Remote Command Timeout". (1000W, 30 minutes later 1001W, 30 minutes later 1000W)

I have something similar for an Alfen Charger integrated via Modbus. To set the charge limit (via modbus write) I have to send the charge limit before the timer expires on the charger, otherwise the charger reverts to the safe value.

I checked the logs and found this at the same time:

It's related to this #114

I was thinking the same, but when I changed it to >= the problem remains. I guess the error and the resetting of the values are both results of the same cause.

Are you sure it is not because of the Battery Remote Command Timeout?

To charge my battery I do as i noted here: https://github.com/binsentsu/home-assistant-solaredge-modbus/issues/104

the only difference is I now have an additional step to set (Storage AC Charge Policy) to off / always allowed depending on time
