I’ve saw this ing my logs, looks like my zwave radio is resetting. Why?
I’ve been having problems with hs-ws200 switches locking up or not recieving messages.
oh shit! ive had this happen SEVERAL times and even let a tech have a look at the logs. this would happen when i was apparently pushing the limits with 300 devices. the only fix was to do a hard reset and start over.
Contact ST support before doing anything drastic such as resetting your hub. Let them investigate the issue. 
just my opinion.

agree. but if resetting hub was only fix, it would be with a new ST hub or perhaps the hubitat sitting on the table still in its box.

the interesting thing is after the reset everything would work like it was supposed to until 300 devices again. at the same time as the zwave radio resetting i was having trouble pairing the monoprice motion-temp-humidity sensors. if they would pair they wouldnt pair completely and it would be under a generic driver and not the custom driver. was aggravating as all get out.
is this a 200 or 250 series v2 hub?
i imagine 200 series, bought when it first released.
I have also been having problems with 2 double fibaro switches for a week.
It is a hub v3.
They stay when it seems offline, they work with authorizations but they do not update their status, nor are they well managed from the app.
I had never had a problem with them.
The zwave repair always shows fails the switches and it is useless to repeat it.
interesting cause that is the same 200 series that i had the problems with the z-wave radio resetting, too
