I am controlling some Zigbee devices in another house. This is not permanent, I need it for about six months.
I needed to get this working quickly, so bought an SLZB-06, configured Wireguard on it to link it to my home network, and controlled it from my house’s HA Yellow. This was particularly easy as my house uses ZHA (which I ultimately want to change to Z2M, although that’s another issue), and having ZHA and Z2M in the same installation is straightforward.
I’ve just had a 24 hour Internet outage in the remote site, which I confess I hadn’t really planned for, and I want to move the control locally so that automations largely continue with the network gone.
I’ve bought an HA Green and I can, in the limit, just re-pair all the Zigbee devices: there’s only about 20, so it’s a couple of hours’ work. A lot of them are INNR bulbs with the six-on-off dance, but I’ve also got some INNR sockets so I can build a little “pop the bulb in the table lamp, hit the button to an automated on/off thing, done” production line. But indeally what I’d like to do is back up Z2M on my HA Yellow, copy it to the Green’s Z2M instance, and have it all just work.
Is this possible? I get the impression that what I need to do is “Download Zigbee2MQTT Backup” in order to get a coordinator_backup.json, and then copy the contents of /config/zigbee2mqtt to the new machine, or…something. It’s not clear. And will that do the necessary work to create the entities within the new HA instance?
