openHAB 2.5.10 on a RPi4, via LAN
RaspberryMatic 3.53.30 on a RPi3, via LAN
Many of my Homematic IP things in OH stop receiving data after some time (typically after some weeks or month, sometimes after two weeks).
This does happen only for single devices, not all together.
Actually a weather station HmIP-SWO-PR, and a HmIP-eTRV-2 (thermostat valve drive) are affected.
The HmIP devices properly receive demand values from OH - at least the thermostat valve; I wonder if setting a demand wind speed would make sense
Within Homematic WebUI I see that the devices work properly.
I saw in an earlier topic, that specifying a callback adress for the binding may help, if OH is connected via LAN and WIFI at the same time (two IPs). Mine is only connected via LAN, but I added the OH address as callbackHost.
Because it is usually working for quite some time I doubt that there is any network or firewall issue.
Non-IP devices work fine all the time.
I know that this no serious way of debugging, but I tried to dis- and enable the thing in PaperUI, which did not help to “reconnect” to the device.
Restarting OH did help. I did not touch anything in Homematic meanwhile.
As far as I know it is OH that polls data from HM.
Is there a way to check, if this polling for a particular thing (or item) actually happens in openHAB, or if this request was answered by Homematic?
And further, how can I check in HM, if the polling/request arrives, and if HM is answering the poll? (yes, I know, this question should be asked in another forum )
