I live in another country most of the time but have a home in the US controlled by a C7 hub. About six months ago, what I suspect was a power outage corrupted its database and bricked the hub. When I was back in the US, I restored the database and put the hub on a battery backup that cannot be remotely administered. This means I can’t shutdown the hub, kill the power remotely and then restart the hub when the Zigbee mesh gets janky and things stop responding. I instead have to shutdown the hub and have a friend go to my house to unplug it and hang out for 30 minutes or so and then plug it back in.
All that said, is there a way to force the Zigbee mesh to rebuild itself without killing power to the hub? TIA for any thoughts.
I just had a look at the Settings > Zigbee Details page and there is an option to 'Rebuild network on every reboot'. If you were to switch that on, then you just need to remotely reboot your hub to do the rebuild. That said if you're already accessing the hub to do the shutdown (presumably with Remote Admin or VPN) you should also be able to hit the 'Rebuild network' button manually on the same page.
I haven't done this but others have plugged their hub into a cloud-based smart wifi plug that is controllable by the plug's native app. Then, you shut down your hub remotely & kill power to it using the wifi plug; wait 30 minutes, then turn the wifi plug back on and your hub should reboot.
Thanks for the suggestion but I was using that solution previously. Unfortunately, now the battery backup continues to supply power to the hub so there is no way to power the hub off.
I'm using an older version of firmware (2.3.2.141) and don't see that option, And because I'm only at the house for a week or so at a time, I've been hesitant to take upgrades for fear of breaking things when I'm away for 3 or 4 months.
I do see an option to disable and enable the Zigbee radio. I wonder if that would force the mesh to rebuilt itself. Perhaps, a developer can shed some light on using that as an option.
I wonder whether there's an endpoint available that does the same as the 'Rebuild network' button if the button is not available on your UI. I'm running version 2.3.9.192 on a C-8.
There are some Wifi and Zigbee USB-A switches. That could be plugged in the USB port before the cable. Wifi would need to be controlled via the web. Zigbee would require another hub for obvious reasons…
wouldn't disabling the Zigbee network work? with the C offline, after 10mins the zigbee would begin the rebuild...
wouldn't it?
Personally, I bounce my hub to force rebuilds but i'm wondering if just disabling zibee Controller would cause it to rebuild as well.
... and if a rule could be written ... maybe you could automate it all...
That is indeed the type of device I was referring to. Hope it helps!
As I understand it, disabling the Z* networks only turns off access from the hub to the radio, but the radio stays on… someone please correct me if this is wrong.
