It looks like it is roughly half of the sensors reporting offline malfunction at this time. Oddly of the ones showing malfunction, they all show the same start time. I wouldn’t expect that from a selection of wireless sensors.
Are these zones wired through a translator or are they all wireless sensors?
If they are all individual wireless sensors, it is definitely strange The first thing I would do is update firmware. Steps are found in the link below. You will need to update incrementally. Update to 4.3.0 first, then 4.4.2 Any change after?
