Hi everyone,
I have a Landis & Gyr T230 Ultraheat heat meter which can send data via wireless M-Bus. I have a Mega 2560 with a wireless RF module and would like to send the meter data to Arduino. However, I haven't been able to find any libraries that could help me. I know that wireless M-bus uses the EN 13757-4 standard which I have studied but I haven't been able to write an Arduino program that would successfully read the data. So interfacing it on the Arduino side is the thing I need help with. I would appreciate any advice as to how to do this or any useful link to a library or software that might help me.
There was already a similar post here: wireless M-Bus library? - Project Guidance - Arduino Forum
but there weren't really any useful replies.
