Thank you for the quick answer.

I used a externel MQTT server. Now i have switched to the guildin flashMQ venus server.

But i can still see no on and off , and current commands.

I use the MQTT explorer for test monitoring.

as i have a Keba charging station i modifiied the path from custom/ev-charger to Keba/ev-charger.

You want to see the changes that are done in Venus OS right? The topics are only one way.

The topic Keba/ev-charger is the receiving one for Venus OS and the sending one for your ev charger.

The topics N/YOURVRMID/evcharger/VRMID/* are the sending one from Venus OS and can be received by every client. The topics of Venus OS reflect the dbus. Therefore here you find the ev charger controls that change.

First i am using OS v3.40~2 beta.

nothing is received . may be a beta problem.
