Hass to Hass, possible?

I wonder if it’s possible to have 2 Hass installations and then connect one to the other one.

Like connect Hass to Hass

What do you want to accomplish?
Some kind of failover / load balancing?

I have 2 house and the Z-wave or ZigBee radio can’t reach beteende the two house. So I thought I install Hass in each house and then Connect so that all I have in one Hass in house 1 will show in my Hass I gave in House 2

No failover, just so that I can controll everything from one Hass.
