[Request] add feature to charge akku with max AC power #1247

Closed onehub278 closed 5 days ago

onehub278 commented 1 week ago

Is your feature request related to a problem? Please describe.

it would be nice to have a feature to charge akku with max AC power (Huawei R4850G2), when energy costs are very low

Describe the solution you'd like

for example: add a max charging power field in watts and overrule auto power charger limiter via MQTT

Describe alternatives you've considered

maybe i can do it manually under "AC Charger config" -> Disable "Auto power charger limiter" -> using "emergency charging"

Additional context

iam aWATTAr consumer and it is possible to get negative energycosts mostly at weekend, but also get very high energycosts at early morning or at afternoon

it seems all necessary commands are already implemented via API or MQTT: https://opendtu-onbattery.net/firmware/web_api/#list-of-urls (/api/limit/config) https://opendtu-onbattery.net/firmware/mqtt_topics/#inverter-total-topics (solar/powerlimiter/cmd/mode)

please close this request

thx
