I am having a very difficult time setting up 5 new Leviton Switches in an already established Leviton Z-Wave Networks consisting mostly of the Vizia rf+ models from years ago. I’ve installed the DZ15S in the thick of what should be a robust and stable network. I am having problems with all 5 of these switches dropping off the network. Here are the facts:
- I added each one and checked that it was correctly added in smartthings. Each time they appeared to be functioning correctly.
- After adding each switch I did a ZWave Repair. No problems.
- I finished up the 5 switches, all working well, even Alexa was happy, and went to bed.
- When I awoke the next day, some of the switches were miss-reporting status, so I did another repair. No joy. Alexa, however, was still able to turn them on and off reliably.
- Now today, I wake up and Alexa can’t control them and they appear off-line completely.
- I went around and manually operated each switch which caused them to reconnect temporarily. Now they are all off-line again. (Just the new DZ15S-1BZs, everything else is just fine).
I have to run around the house and manually switch all my switches to keep them on-line. It’s almost as if they go into some sort of sleep mode and need to be woken up. Is that a default setting?
I hope someone out there has encountered and solved this issue, because I don’t want to have to remove them all and start over (took a long time to deal with wiring and tight junction boxes!)
6/30/2018 8:06 PM Update: More weirdness. When the switches are on-line, they do not report status correctly in Smarthings App, and cannot be controlled from the app. Oddly, Alexa seems to work just fine, even though it is discovering the devices via SmartThings. More and more this is appearing like a problem with the Z-Wave Switch Generic device driver, or perhaps Alexa can tolerate lack of correct status updates from device. The plot thickens.
