Hi to zigbee users - my first around here.

#

Is there a source on information on using zha with conbee 2? I have HA and ZHA on a Nuc with Conbee2 and about 20 zigbee lights. It works well. I want to have a warm start backup Nuc and Conbee 2 to fire up if the regular system fails. I have read what little I can find and have tried various ways of backing up the zigbee config files in HA but have failed to get the backup Conbee 2 to connect to the lights.

The only way at the moment to take a backup of the Conbee is with deCONZ

#

Most of the network state is stored in the stick itself so you'd have to make a backup of your working stick with deCONZ and restore it to your second stick

#

Not too sure how you're managing the "warm start" part but as long as the the two sticks have the same network settings written to them and you somehow share the HA config folder between your two NUCs (namely the zigbee.db file and the stuff in .storage/core.config_entries pointing to the serial device), you should be able to swap between hosts without issues.

#

Just make sure only one coordinator is on at any given time. Otherwise, bad things will start to happen.

Thanks for quick reply, puddly. That would be a tolerable solution. I understand that deCONZ is an alternative to ZHA. can you give me a pointer or two suitable docs for learning about it?

You don't need to switch to deCONZ to use its backup/restore functionality

#

My experience with deCONZ is limited to doing backups so I'm not the best person to ask about how to actually use it...

Well backups would be alI need it for. My configuration is reasonably stable so if I can get a copy Conbee to go with my backup Nuc I should be able to fix a system failure.

To be honest, the Conbee is not really the best coordinator to be using if you want to reliably fiddle with network settings like these. The EFR32 and CC2652 sticks have documented backup/restore functionality with a few command line tools and those 100% clone the device state to different hardware.

OK I can cope with bad news! I will also have to read up on them. I have done a few construction jobs but I would want to get these sticks as finished devices.

If you want to try it with the Conbee, the backup stuff is done with the Phoscon web interface by clicking a few buttons. It's relatively straightforward if you can get all of the deCONZ stuff installed.

You have given me a lot to get on top of. I will begin reading up on deconz, Phoscon and theh other sticks. Thanks for your insights.
