Control charging of battery based on price #190

Hi I am about to invest in probably a Huawei inverter. In Homey I know when prices are high and low from my electrical company. Is it possible to control the inverter that when the price is low it should charge instead of having schedules in the inverter? More or less every hour tell the inverter if it is a charging hour or a discharging hour?

Huawei does not have a good public API to do this. I would opt for another brand (SolarEdge, Enphase, SMA) if this use case is important.

Hi, updating this case.

As you see in attached pdf it should nowadays be possible to control charging through the API. This would be very very interesting.

What do you think about this? For me it would be good enough to be able to set for example two periods at the time. For example

Charge between 02:00 and 06:00 (or for how many hours, 02:00 and 4 hours) Discharge between 06:00 and 02:00 (or for how many hours, 06:00 and 20 hours) Every hour when I get new electric prices from Tibber in my case (or Nordpool) I could let homey send new schedules.

What do you say about this?

Best regards
