I have a detached garage where I have 3 Ecolink Zwave Plus sensors as well as an Inovelli switch.
The garage is only 8 feet away from the nearest Inovelli switch in the house which is right next to a sliding glass door.
The switch in the garage is terribly unreliable. Sometimes it works great, other times it will be a delayed response. Other times it will not respond remotely, but when physically toggling, the on/off will show correctly in the Smartthings app.
The battery powered Ecolinks work perfectly and they are further in the garage than the switch is. They work regardless of whether the switch is there or not.
I have gone through 3 switches to eliminate the possibility of them being defective. All switches will only pair if I am in the house. They will not pair in the garage. The Ecolinks paired immediately and without the switch installed and no other repeaters. I have done Zwave repairs each and everyone I tried a new switch in the garage. After I pair in the house, I move out to the garage and do a Zwave repair. Usually, that switch fails to update mesh/route. It will still “kind of” work though.
On the other hand, a GE Zigbee switch controlling pool Lights in a metal box even further away outside with no repeaters near it works flawlessly.
Anyone have any ideas on what is going on here? These Inovelli switches are supposed to have powerful repeaters built in and I have over 30 of them in the house - all work great. The garage is only 8 feet away and battery operated Zwave and Zigbee devices are performing flawlessly.
