Perhaps caused by the change in account / configuration on the panel
If they only have supervision problems that might be fixed by adjusting a configuration option.
Do they still report open and close reliably at the panel? If the sensors still open and close normally, but supervision fails often, then they may just not send supervision signals at the expected appropriate interval.
You could adjust the supervision interval your panel checks for sensor transmission and increase it to give those sensors more time to check in. It looks like your panel supervision check set to 4 hours. It can be increased to 12 or 24. Try increasing it. Do the errors stop?

In the prior response I suggested testing sensors by moving existing sensors and seeing if the problem followed the sensor. Did you try that?
I’ve never actually seen anyone trying a Versa sensor before. I am not familiar with them, however, Versa Mini sensors are not tested and not found on the manufacturer’s compatibility list. Here is a list of officially compatible sensors. See the 319.5 mhz section.
That compatibility list is direct from the manufacturer of the panel.
If you updated the firmware on the panel it may be that newer firmware updates have caused an issue with the sensor, but it is far more likely to be just a general issue with the sensors if they are all doing it, hopefully just a slower than normal supervision signal.
