Works perfectly!
Everything worked perfectly in the first test run. The initial setup is straightforward using the included instructions. However, it's best to be familiar with your router to assign the Victron2MQTT a static IP address so it remains consistently recognized on the network.
All very good
Everything okay
Great part
