@Sarel can you share your method for inputing battery charge/discharge into HA. I’m struggling with this…
Under setting then dashboards, the energy dashboard looks like so:
And the battery looks like this:
This is a BYD on CerboGX

This helped to confirm the following: Battery sensors for charge and discharge · Issue #89 · sfstar/hass-victron · GitHub bug in the hass-victron integration. Zero values in these 2 sensors.
It’s like you’re just ignoring me
Sorry @FredHen… - Was that me… thread is split into 2 parts I think…
Do you know if it is possible to import into HomeAssistant? I’ve never tried to pull in data from VRM to HomeAssistant, just worked with ModBus to the Venus thus far.
I don’t use Home Assistant, but looking at the Venus OS Large image: Signal K and Node-RED [Victron Energy] they point to the API docs and specifically the VRM API documentation (victronenergy.com) stats call which includes the irradiation forecast.
It sounds like a simple API call that can be integrated into Home Assistant.
On a side note, not sure if you’ve seen the blog post (Introducing Solar Production Forecast - Victron Energy) which explains the forecast a bit better.
Using MQTT Explorer I see these 2 values are null so I have found the issue… I think.
If they are null then the integration also displays null in the HA Energy Dashboard.
@plonkster Is this an issue I should raise on the modifications forum for Victron? I don’t know what the exact issue is or how to frame it?
Battery with DeviceInstance 512, which means it is a CAN-bms battery. Not all those batteries support energy counters. In fact few do. I assume yours doesn’t.
There is code in vrmlogger that calculates it from the other values (Multi, SolarCharger, etc). But that is not available on dbus/mqtt. You will have to do it yourself.
Or fit a SmartShunt/BMV to get these values. Or plead with battery maker to add them. CAN bus message 0x378.
