Integration with Fronius and Victron

Configuration
1

Hi all,

I have recently energized a Victron Energy system I also have up and running a Net metering system that includes a battery:

  1. Fronius Gen24 Plus
  2. BYD HVM 11.04
  3. 4.92kwp solar panels

Grid and Fronius work in parallel prioritizing first the consumption from Solar/Battery and last Grid
Victron treats the grid (and Fronius) as a generator and has two relays:

  • Relay 1 switches to Fronius on demand or if battery falls below 20% it performs passthrough of consumption and a light 5A charge of Victron battery
  • Relay 2 works only if Relay 1 is activated and charges the battery with 40A (it doesn’t do anything else)

So far the Fronius integration to HASS has been flawless and although I am novice I managed to create a few automations.

What I want to achieve is to control both Victron relays through HASS.
This way when Fronius reports that the Solar production is above e.g. 1.5kw relay 1 should open. Once the solar production is above e.g. 2.9kw then relay 2 should open etc.

Does anyone have experience with something like this?
I am currently looking into videos on how to integrate Victron to HASS(not so easy for me) but If I manage to do it will such automation be possible?
Thank you in advance for your time.

Any feedback would be greatly appreciated

I dont know Victron but Fronius. If you know a way of connecting to the Victron please share which one you use and your actual device (i found multiple types for Victron), where you got and where your problem is.

That depends on the entites you get from the Victron. Also maybe it has dedicated hardware I/Os so you can connect the I/Os from the Fronius.
