Two or one?

Installation
1

Hi,

We will soon be moving from our detached house to a new house. We are moving into a new house with my parents. We live on the first floor, the parents on the second.

Now the question. Should I rather install two home assistant instances or control both floors via one instance? Mine is currently running on a Lenovo Tiny PC. In the case of a second instance, I would simply set up a second Tiny PC. Or is that too much for a few lamps, shutters and sockets etc…? The parents should get their own IP range so that the networks are separate.

Thanks for your ideas
Enni

I will go with one. PC is enough for that. And all the bother with updates and errors would not come double…
Also makes it easier to make cross floor automations.
Like, for example, an assistance button for your parents. They just click a button and you run upstairs :slight_smile: The best automation ever, they would say… :wink:

Ok. Understand Mischa. And for Grouping the rooms i divide it in two different Lovelace Cards, right? The plan is to install two tablets per floor to use the lights and so on.

I agree with @BebeMischa

Just create two dashboards and user accounts for every family (parents and yours). I would also suggest you deploy a single IP network and if you want to segregate things do it with VLANs.

Single LAN and single HA significantly reduces management overhead.

Best of the luck with the move.

Thanks friends! But one question - when they have a own VLAN (192.168.3.) and they have own a Wifi device (f.e. 192.168.3.122) - see the HA (192.168.1.10) the device?

It can if you allow VLAN tunnelling. For your use case I suggest you do not use VLANs just a single IP net, say 192.168.3.0. If you want more than 254 hosts on the LAN just use a /16 (255.255.0.0) instead of a /24 (255.255.255.0) subnet mask, or anything between /16 - /24. /16 supports 64,000 hosts.
