Victron GX integration

To work, this needs

• https://github.com/freakent/dbus-mqtt-devices
• MQTT broker on the Victron controller to be active:

If you are not using the Home Assistant part (only MQTT), you must remove the api: line from your ESPHome configuration, otherwise the ESP will reboot every 15 minutes because no client connected to the native API.

I tested this on a Raspberry Pi with Venus OS, but I don't have a Victron setup (yet). The meter shows up like expected, but was not yet tested on a full ESS system:

I'll maybe add other configs later to add PV inverter data to a GX device via MQTT and Home Assistant.

esphomedsmrvictron's Issues

Question: How do you handle returning energy to the grid?

I'm currently developing a small script to pull MQTT data from DSMR reader to Victron.
But for some reason my power that is being returned to the grid isn't shown in the victron gui.

Since you're also using a Dutch DSMR variant, I'm wondering how you handle it. And if it's even an issue with your code.

Need code for PVInverter PLEASE :) :) :)

It would be great to get the same "code" for a pv inverter.

Many thx for this code, it works great !!!! :) :)
