Multiple hass.io instances on 1 network

Installation
1

I have been using hass.io for about a year now - my current one is in my living-room & must stay there because i use bluetooth to monitor several sensors around the home - i’m looking to set up another in the summerhouse to monitor plants in the garden (purchased 4 xiomi plant sensors) but they are too far away to work with my home assistant. i can’t move the pi because its then too far away from the sensors in my livingroom.

can i use 2 Hass.io rasperry pis on the same network? has anyone tried this?

i tried a basic fresh install & hooked it up to my network but the external access to the first one got messed up & i could only connect via ip address trying to resolve hostnames just didn’t work

i think I will need to change some things such as host names & network settings to avoid conflicts

i don’t necessarily need the 2 installations to share information but it would be nice if they could - would save having to switch from one to the other.

any ideas thoughts input would be greaty appreciated

I dont use hass.io but I have 4 HA instances on my network. They just have different IP’s, otherwise no difference. You might want to change port number if you want to expose more than one to the internet. I also have mysql on one computer that holds one database for all HA’s so the logbook has all their activity. I statestream everything and take what I need from each other with MQTT.

Perhaps this could be an alternative (no second HA instance needed):
