I'm currently implementing wmbusmeters in multiple buildings where a lot of (10....30 each) older M-Bus devices are already installed. So far testet, the most devices do not have a driver available in wmbusmeters.
When testing with libmbus I see the important data from inside the telegram.
So, it would be great to have a kind of "generic" driver in wmbus which simply parse the telegram and show all data inside as JSON/Fields/HR without any device specific filtering. This could be a good fallback driver to be used if no other driver works.

You can also write your own driver as a text file and just use that. Check this one out:
https://github.com/wmbusmeters/wmbusmeters-drivers/blob/main/wmbusmeters.drivers.d/kampress.xmq

Change the name to your new driver name and change the file name to the same.
Then just put the xmq file into /etc/wmbusmeters.drivers.d and you use the driver directly.

A generic driver is pretty useless except for the most simple meters. What you want to add is the knowledge
of what the bits mean and what volume in storage 1 means, last day, last month last year etc.

What kind of meters are the ones you are reading? Water, electricity, other?

Sorry for asking so much stupid questions, I'm really new within M-Bus technology and miss a lot of basics. Meanwhile I've multiple projects with a lot of older wired M-Bus devices of all kind (Electrical, Heat, Gas, WaterMeters) already installed. The aim is to read them out. So far I've testet 2 devices and both don't have an driver available (GossenMetrawatt U1289 and EMU 1/40 both ElectricalMeter)
The wmbusmeters-drivers project with the .xmq text-files is probably covering what I need, I will check this soon - thanks.
