In-wall GE Switch ZW4003/12727
This switch has been working for several years, but started misbehaving in the last few months – intermittently it stops responding to Smartthings and it also stops operating manually (eg, flipping the switch has no effect on the bulb).
I removed it (four taps up, four taps down, then did z-wave exclusion from the hub) but cannot get it to add back. Oddly, the Smartthings iOS app only shows zigbee switches under GE now, and whether I choose that or generic z-wave device, it just times out when I try to add it.
Does this switch have a physical problem? Any advice on how to get it to successfully add back?
Thanks in advance for any advice.
