I am using a 2GB Raspberry Pi 4 and have reached its limits; I want to install “Sendspin Bluetooth Bridge.” I have another 2GB Raspberry Pi 4, so I installed Home Assistant (HA) on it and added the “Sendspin Bluetooth Bridge” add-on. I wanted to know if running two HA instances side-by-side could have any negative impact on the proper functioning of the original instance ?
Short answer. Yes
Imagine i.e 2 instance named homeassistant.local:8123
Or 2 instances of Same Integrations/Devices or Services
So, You have to Know Your Network, And how The HA’s/Devices/Integrations/Apps Talks to each-other, and externally( If that’s the case also ) , So there a few thinks You have to take into consideration, in regards What&How You run/Install on each, and also As Mention, Know Your NetWork
