Hey all,
I’m working on a backup/failover setup for my Home Assistant instance and could use some input—especially around handling the Z-Wave USB stick.
The goal is to have a backup system that I can start up remotely if the primary HA system goes down. I’m using Docker on both machines, and I have volumes for HA, Z-Wave JS, MQTT, and MariaDB syncing to the backup.
Where I’m hitting a wall is with the Z-Wave stick. I have a second identical stick and can do an NVM restore if needed. So in theory, I could have that plugged into the backup system and bring it online. But obviously, having both sticks active at the same time would cause problems for the Z-Wave network. The backup system is typically off but comes up periodically to sync the docker volumes.
I was hoping to just cut power to the sticks using a powered USB hub, but turns out the powered hubs I have still power the stick even when the external power is off.
Has anyone figured out a clean way to toggle USB power remotely or otherwise disable one stick before bringing the other online? Would love to hear if anyone’s done something similar—or if using a secondary controller is a better route.
Thanks in advance!
