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. > **[GX Modbus-TCP Manual \[Victron Energy\]](https://www.victronenergy.com/live/ccgx:modbustcp_faq)** [https://www.victronenergy.com/upload/documents/CCGX-Modbus-TCP-register-list-3.60.xlsx](https://www.victronenergy.com/upload/documents/CCGX-Modbus-TCP-register-list-3.60.xlsx) ---

> [@pekkaj](#): > > charge the battery when electricity is cheap 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!
