I’m having a weird problem with a new Leviton DZ15S light switch that I just installed.
The switch operates normally as a manual switch. That part is good. But it’s not communicating properly with Smartthings. When I first installed it a week and half ago, everything seemed fine. But a few days ago, I noticed the weird behavior.
First, it seems to timeout. After some amount of time (that I haven’t figured out), Smartthings starts reporting that it is unavailable. I lose all ability to control it from Smartthings. If I tap the paddle, it will reconnect, sort of.
When the light it off, the app will report that it is off. I can then turn it on from the app. However, the status does not update, and I can’t turn it off from the app. Also, when I turn it on manually, the status does not update.
Any ideas why the switch is only sort-of interacting with Smartthings?
