Under one HA cloud subscription run more than one Raspberry

HI, this is my first post after I signed up for cloud and I start to learn those hundreds of new terms. I wonder if it is possible to run 2 (instead of currently one) Raspberry 4 in my house, to split the load. For example house and garden. Each Berry has their own MQTT broker login but are in the same WIFI. My first question is: is it possible under one cloud login (both Berry login the cloud with the same credentials) and I can see all my devices from just one webinterface (one nabu.casa adress). In other words: each device connects to just one Berry and both Berry connects to one HA cloud account. Device would have a unique name. See, I want to use my existing Berries till they stop working and not always buy something new and increase e-waste. Thanks for your thoughts! Martin

Not needed and would be more trouble than it is worth. A pi4 is more than capable of running an entire home.

No. Each server must have its own cloud account.

Thanks a lot!

There are load monitoring add-on tools available too see how your HomeAssistant server is performing.

Hopefully you got a Raspberry Pi with enough memory and you should be fine for now with just one. 4Gb is fine. Higher is nice.

The upgrade path is easy if you need to put in faster hardware. Install the new, backup the old and restore to the new.

Given you can see all devices on one screen, I suspect they are all on one server, and the other one is actually superfluous (e-waste at installation time)… Maybe you can repurpose it as a PiHole?
