M-Bus (Meter-Bus)

Some one that have manage to connect to M-Bus (Meter-Bus)?

Post a link to the datasheet with the M-Bus specifications.

I just managed to do this. Unless you have already solved this issue or given up, I have just started a project on GitHub - roarfred/MBusMqttLogger: An M-bus master that poll a meter and logs data to an MQTT server

It's currently work in progress, but might be useful. You'll find the M-Bus implementation in MBus, Telegram and UserData

This is currently working with this hardware: libmbus/MBus_USB.pdf at master · rscada/libmbus · GitHub
(I am just using the part to the upper right and a separate 30V PS, directly to IO pins on a ESP8266)
