Hello,
I think it started with 91.0. Suddenly all my Z-Wave devices show as not available on my pages. When I check it on the States page, I do not even see any Z-Wave devices.
After reboot almost everything works. The only device that does not work is Aeotec DSB45 Water Sensor. It shows now as Node 7, but it does not have state and battery attributes anymore. I tried to heal the network a couple of times, but every time it kills all other devices. I have to reboot my HA to fix them.
What can I do? Any ideas?
