I want to build a fault-tolerant network, and one of the concerns is the zigbee coordinator failover to a different device.
I am a smart home enthusiast and I have a some background in high availability servers, so I decided that my smart home must be fault tolerant.
I have a Home Assistant server and a number of zigbee devices on my network. Home Assistant server has an XBee and is a coordinator for the network. I want to have a server in a different location of my house that will be able to completely replace the primary coordinator in case of a disaster. All devices must remain in the same network, and request to 0000 address must be routed to the new coordinator.
I've read https://www.digi.com/resources/documentation/Digidocs/90002002/Content/Concepts/c_zb_replacing_coordinator.htm , but I am not ready to disable encryption. Is some solutions with encryption available?
If I configure both with the same key with KY, would that be enough?
