Hi. I have recently done a factory reset on my ST v2 hub (because of all the hoops and configuration changes made in attempt to keep it working properly during the recent and extended outages/performance issues). I already had a GE In-Wall Smart Dimmer switch Model 12724 connected to the hub before the hub reset.
I am unable to get that switch to “clear out” its prior information on the original hub pre-hub reset. At least that is what I suspect, as the switch is unable to pair with the newly reset hub. I have tried every combination that I can think of regarding doing the Z-wave general device exclusion, hitting on/off buttons on the switch (while the hub is sitting next to it), pulling the air gap switch on the light switch, killing the power to the switch at the breaker box.
The only instructions online that I have been able to find regarding what to do on the switch itself is “usually press a button on the device”
I love how the ST instructions for z-wave instructions say “follow device manufacturer’s instructions to exclude” and the GE instructions say “follow z-wave controller manufacturer instructions to exclude.” Really helpful.
I suspect once the switch is correctly excluded, it will connect correctly to the newly reset hub. That said, it is possible that the switch is already excluded but is just not connecting. I have tried everything there too. Hitting off button 10x times while trying to connect (which was what had worked previously), pulling air gap switch, hitting on/off, etc. Again, I have the hub sitting right next to the installed light switch.
