I have several Homematic IP Items connected via Homematic CCU2 and openHAB 2 binding.
Everything worked well for several months
Now I have three of six devices that don’t get any updates from the CCU - or don’t react to updates any more.
E.g. a temperature sensor that’s flat for several days. Updates are propagated from the sensor to the CCU and visible in the WebGUI there. But the updates get lost from CCU to openHAB.
The other three are fine…
There is nothing in openhab.log (Really, not even mentioning anything from homematic for weeks)
Do you have an idea where to look? I’m about to install everything new, but really would like to know what’s going on to prevent that happen again.
rule "check for undef"
when
Member of gMyGroup changed to UNDEF
then
var String msg = String::format("*Offline* = %s\n", triggeringItem.name)
logInfo("offline", msg)
end
Hello,
How does the item change to UNDEF? I have a situation where some sensors stop sending temperature and pressure updates every now and then. I have a field that updates to show the date and time the last status was received but recently I realised that one of the sensors hadn’t updated in 10 days and I did not realise and wanted to create a rule that would send me notification if the status does not update for a while.
first of all, I have the same Problem at different divices at different Locations.
So it seams to be an generall problem?!
Now, my question to the conversion at the beginning:
Am I right? With this solution you will find out that one item is UNDEF but you will do no more actions?
How can the general Problem be solved?
In my case, the item is still up to date in the ccu2 but openhab has still an old value.
This problem is only with homematic IP devices.
Sometimes I am going to restart the Openhab server or / and the CCU2.
