I would like to be able to read how much watter me and my family are using in a day, week, month and year. My Wattermeter brand is GWF (Swiss company). I don't know them but it seams that there tool has a M-Bus port. Wich I can imagin that would be great.
In my dreams :), I would be able to connect a little sensor to this mbus port and this sensor is sending the information on my openHab system. I do also have a homematic system, maybe this would also work with this.
And the same company has a M-Bus solution
Thanks you verymuch for any kind of help
