OH3 Comfoair binding - item not updated

Dear Hans

over the last days I noticed something strange and I don’t know where it exactly comes from. So let’s start.

  • OH 3.1.0.M4 - Milestone Build

I have two rules which control the speed of the Airing. Which both are working fine.
Some days ago I implemented another rule that check twice per day the difference between filter runtime and maximum duration. And sends it out as a mail containing

Filterlaufzeit: 2856 aktuell 2401.0, verbleibend 455.0 Stunden.

While the control rules due theire job. At some point to notice rule still gets executed but the value of
comfoair:comfoair:64509ff4:times#filterHours stays the same.

As you can see from this, it was last updated yesterday in the evening. The value corresponds with the value that I received tonight (2021-06-18) at 18:00

Also other items where stopped to be updated and only the commandItems seem to continue to work.

Kind regards

Hi Stefan,
not sure if this is directly related to the binding. Hence, a TRACE log would be helpful to see if the binding is actually pulling the states from the device. Could be that the according thread got stuck.
Also, there were no changes to the binding in OH 3.1.0.M4 (there are some in M5, but those should not be related) so if it was a general binding problem, I’d expect it to have happend more often to others as well.

Hi Hans

I’m also not sure if it is directly related to the binding. This is just the spot that i saw. Meanwhile comfoair runs on TRACE level. And I hope to catch something over the next days.

I’ll update here as soon as I have more.

Edit 03.07.2021:
Currently it looks stable. It seems that another one binding config was the issue for this.
