ADFWEB (Mbus) to MQTT / Homey

(@Admin move to off topic if needed)

///

I have a couple of Kamstrup 603 Ultraflows with MBus modules i wanted to connect via MQTT to Homey for getting temp/flow/litre pr s/kWh etc.

Essentially i want the homey to control my dry chiller coolant/heat loop. Nerd

Question:

ADFWEB have all sort of BUS/NET → MQTT
Gateway MQTT from/to M-Bus

The possibilities could be endless with Homey coupled with MQTT:

Do these 200€ BUS/NET converters actually work?
