Adding Victron Multiplus as an inverter

[persil1971]

Victron Multiplus and other inverters have an integration to Home Assistant already and also have available MQTT and Modbus over TCP interfaces. Would it be possible to add this to a development queue for future integration? I have implemented predbat with GivTCP and GivEnergy for friends but developing an integration is not something I can do!

I just came here to see if anyone has done this. I have a lot of control over my MPII from HA for saving sessions and such already but would like to get PredBat working and move to Agile.

I'm somewhat struggling to understand the documentation in whats required for non-Giv inverters. It looks like I already have a lot of HA entities for whats required (house/car/solar/export/etc) for a template but struggling to stitch it together.

+1 for me.. i am now using the Victron ESS/DESS but would like to take it into HA

+1 for me too. I'm surprised Victron isn't supported,

It needs someone with a Victron inverter to work out what the entities for SoC, current state, discharge rate, etc and control commands are to charge, discharge, hold charge, etc.

There's at least 4 people here who have Victron inverters, the author of Predbat doesn't, so it's really up the community to work it out. This is how all the non-GivEnergy inverters have been added

Instructions on adding a new inverter type are in the documentation https://springfall2008.github.io/batpred/inverter-setup/#. The formatting has got messed up, but it starts half way through the Sigstore entry: https://springfall2008.github.io/batpred/inverter-setup/#sigenergy-sigenstor
