So my new Zen77 dimmer "thinks" it's off

I recently installed two ZEN77 z-wave dimmers along with a Zooz 4-in-1 sensor. I'm using motion to turn on the Kitchen ZEN77 and turn off after 2 minutes when the motion stops. It mostly works, and pretty much always turns on OK. But sometimes it won't turn back off. The logs show that the switch is "off" and the device status is "off", but the light isn't really off.

I see this:

and this:

I'm not shocked that the route from the Hubitat to the Kitchen goes through the Family Room ZEN77. The distance from the Hubitat to the Kitchen switch is about 21' but that's through a brick wall and a drywall wall. The Family Room switch is 30' from the Kitchen switch, but it avoids the brick wall.

A few days ago when I first stumbled upon the Z-Wave Topology map, there were only blue squares. I can't say if the route from the Hubitat to the Kitchen switch was direct as I wasn't looking so closely. Do I need to add a plug-in Z-wave something in between? Is there a better fix?

(Not sure if it matters, but I have 10 Zigbee devices as well.)

I wonder if the Zooz 4-in-1 sensor might be causing some Z-Wave mesh issues? This often happens with the original (Not 700 series) Zooz 4-in-1 connected to the C7. It can especially be an issue if there are many of those on the hub.

A -6db RSSI is fairly weak. That is also evident with large number of route changes.

I would suggest either more Zwave devices, or a dedicated repeater. Maybe even rotating, tilting on edge, or relocating the hub might help too.

I would think that with so few devices you aren't going to get a good mesh period, you just need more devices to fill in the gaps.

If I relocate the Hubitat, how long does it take for everything to adjust?

I would say overnight would be a good timeframe to wait and see results. I would be tempted to run an individual repair on that node and see if that made a difference after moving the hub.

But I think you still are lacking the number of devices needed to form a mesh.
