I like to share with you my protocol code for ORv3 dedicated to read out Multical(R) 401 Heater Meter from Kamstrup. You can find it at Github: GitHub - siliconehuntsman/mc401: MC401 Protocol for Open Remote v3
It is fully functional code, though it requires hardware part either from Kamstrup or DIY to communicate with the meter. I will document the simple circuit soon. The code has been tested outside of OR server with limited “manual” in-server tests.
This is my first real Java code and effect of OpenRemote server exploration. I’m open for any suggestions how to improve this code.
