Are there any possibilities to connect to my wireless M-bus units that registrates water-, heat- and electrical-consumption? My units are installed by Mälarenergi in Västerås Sweden. In fact I don’t know if they are on 868MHz or 433MHz. Both frequencies are available for M-bus standard.

The only way I can discover so far, is this (probably not easy peasy) solution below. (When M-Bus messages are converted to MQTT messages, you can use them with Homey):

Hi,

Did you get any further with this?

I’m intetested in doing the same. Reading both water consumption and my heating wich is “fjärrvärme”.

Hi Tobias

Unfortunately not. No-one seems to have done this, and I am not skilled enough to start programming this myself. So I gave up.

Hej,

Jag förstår.

Har inte heller kunskap om programmering.

Vi får se vad det landar i.

Tack för svar i alla fall.

Mvh Tobias
