I would like to run Venus OS on Raspberry PI to command Multiplus II to charge the battery when electricity is cheap. Is there any example/reference project here that does that? Would save lots of effort if someone has figured out some of the key parts. I already have mk3 USB dongle for connecting raspberry to multiplus.
NodeRed in the large VenusOS image could probably do what you want.
Home Assistant could do it, but that is a big learning curve. You would use the Victron MQTT bridge integration.
You can program it manually using ModbusTCP or dbus code running on the Pi.

If it is during a known time the ess and scheduled charge will also do the trick.

Yeah but I want to look up prices online.
Forgot to mention that I would like to learn Home Assistant since probably going to build other stuff later too. Just interested in this stuff as a hobby.
Ok so something like DESS?
Was not aware of this DESS, thanks!
