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.
