I have around 120 zwave devices. Was using a 700 stick with the latest firmware and network kept going down.
Started completely over with a Zooz 800 stick and have added most (115) of my devices back. Without security this time. Network was pretty reliable. A few devices dropping that would come back with a ping.
I updated the stick firmware to 7.19.3 a couple days ago and back to the same behavior as with the 700. Network is unusable.
If I restart the addon everything comes back for a little while but then the devices go back to unresponsive.
The only other thing done was the OS update for HA that I took after the firmware update. Should have waited on it to avoid too many changes but didn’t.
I don’t look forward to starting fresh again (just to have it repeat) so would appreciate any help to track this down.
