Linking a parent HA instance to a child Ha instance

Configuration
1

So I now have two instances running. THe big one in the basement in a beefy server and a small one in the living room, CEC controlling the TV and being the Zigbee Gateway.

Is there a way of easily integrating and controlling the entitites from the Gateway into the big instance?
I know, there is a way of having a python CEC server that the beefy instance can connect to. But this would involve altering the OS away from vanilla and easy restoration. SO this would be my plan B.

Thanks, looks very promissing. Do I only have to install it on the parent system or also on the child installation?

Just the parent/primary system. It uses the API of the other system(s) to connect to them.

Thanks for the tips, yesterday I went with the minimal remote-homeassistant config and it did not work. By adding an long live api key it now is connected and I see the child entitites.

I’ve raised an issue on GitHub to make the documentation explicit as I thought it was just me who wasn’t sure where to install it :slight_smile:
