Taking sensors from one HA install to another (bathtub water sensor woes)

Hello,

I have a PI4 running my original HA install. It’s worked for a few years and I am migrating across to a new mini-PC device which is more stable etc.

However - I have a Zigbee water sensor attached to the old install. Unfortunately, this water sensor is under the bath. I can access it, but would require a little more work than I’d like (resealing tiles etc).

So, before I go down this path - is there a way to do this ‘digitally’ - and to somehow trick the sensor into now working with the new HA server?

To (possibly) make matters worse, I use a different Zigbee dongle on each one:

Raspberry PI4: HA SkyConnect
Beelink mini-PC: Sonof Dongle Plus (CC2652P)

Hope to hear,
Neil
