first off all I want to thank you a lot, since 2 month I’m proud owner of a Pi 3b and a running version of Openhab Snap 2.3. As gateways I use rfxcom for my Somfy rollershutters and some intertechno devices and a ccu 2 (plus lan gateway) for my Homematic devices.
So far everything is working fine for me with the help of all this documentaions.
But now I have got a problem that is not solved by reading any of these, I try to add my first Homematic IP device: HMIP-SRH
Auto detect finds it in paper ui and it works fine until I have to reboot the ccu2 than it says:
‘homematic:HmIP-SRH:OEQ0456678:0007D7099D08BD’ changed from ONLINE to OFFLINE (COMMUNICATION_ERROR): java.net.ConnectException: Verbindungsaufbau abgelehnt
I tried to create a new sytemd as suggested in one post -> whole system down had to use my backup…
I tried to set the aliveInterval to 3600 -> no change.
My Firewall settings in the ccu2 are: Remote HomeMatic-Script API “Vollzugriff” and the IP of the Pi is mentioned under: IP-Adressen für den eingeschränkten Zugriff
The only way to get the Device back online is to change any of the settings of this device or of the ccu2 via paper ui.
But I need 17 of this devices for my home so a manuell reboot is not a appreciated way.
Any hints? Need more information about my setup?
Thanks a lot.
