Hey Martin,
I have the same issues with some HMIP sensors and tried to install the updated binding w/o success so far.
My environment:
OH 3.0.1 on Raspberry 4 and a CCU2
Steps I did to enable:
Uninstalled the HM 3.0.1 binding
systemctl openhab stop
openhab-cli clean-cache
cd /usr/share/openhab/add-ons
wget https://github.com/MHerbst/openhab-addons-test/blob/master/org.openhab.binding.homematic-3.1.0-SNAPSHOT.jar
Everything looks good so far:
…I also installed the additional packages:
![]()
After that I started OH again and checked for the HM binding:
Somehow it does not show in the list - any ideas what could be the reason?
Thanks!
