My HA configuration has grown to be more integrated into our home. This means that failures have become more significant.
To mitigate failures I have bought a second set of kit (RPi, Conbee 2) and copied a snapshot onto the SD card in the RPi. This means that, in the event of a failure I can unpug the Rpi, plug in the new one and we are back running in about 5 minutes, albeit with an older config.
The outstanding question is the Conbee 2 zigbee controller. Given that the USB device is addressed /dev/serial/by-id I assume that this will need to be changed in the standby configuration? This could be done offlline beforehand so isn’t a problem. However, if I replace the conbee 2 am I going to have to re-pair all the zigbee devices to the new one manually? This is not really acceptable.
Is there some way for the standby stick to pick up the configuration of the live stick such that no device pairing is required ?
Thanks in advance.
