Master/Slave in hot-standby

Could not find a good answer, so asking here,

Is there a way to create a master/slave installation of HA? Where preferably the slave is a hot standby of the master. Meaning if the master fails, the slave takes over.

In an ideal world we could even do some load balancing, or split certain tasks between the master and slave, but that would be an additional feature.

I guess the biggest issue will be adding and sharing a second z-stick in this case.

Any idea’s?

Search the forum for high availability home assistant. (HAHA)

Put your zstick on another machine and use zwave2mqtt? Or zigbee2mqtt?
