Welcome! I'm new to this forum.
I'm a happy owner of an off-grid setup: Quattro 48/8000, BMV-700, MPPT 250/85 (15 solars @250W), Sunny Boy 2.5 (10 solars @250W), CCGX, and lead-acid 48V 800Ah. The setup has around 5 years.
Recently I discovered Home Assistant (the main goal being to automate car charging only when batteries are full and there is a surplus of energy). The first tests are very positive :)
Incidentally, I discovered a potential glitch...
I'm using Modbus to integrate CCGX in HA, and the values I used for Wallbox are correct (at least similar to what I see in CCGX), that is:
- com.victronenergy.battery Battery voltage
- com.victronenergy.battery Current
- com.victronenergy.battery State of charge
- com.victronenergy.system AC Consumption L1
But when I started (out of curiosity) to play with Charged Energy and Discharged Energy (from BMV history) the Modbus gave me very strange values...
The values I see in HA:
the definition of sensors in HA:
and the templates to apply scalefactor:
The definition in HA is fairly simple (and it works fine for other values), so I wonder if it can be a Modbus or BMV issue?
