Best practice for a HUGE device with 100s of entities

Hey everyone. I have an old-school HAI Omnilink II Pro home automation (from before Leviton bought HAI and shut it down:) which does lights, motion, audio zones, basically everything in my house.

I have now it properly configured in HA through OmniLinkBridge through MQTT - which works like a charm even though OmniLinkBridge is not being maintained anymore.

Anyway my question is this: other than my IoT devices, I now have a single huge Device called Omnilink and the Device has about 450 entities (!) which include lights, PiRs, thermostats, audio zones, and some macros I have set up on the Omnilink. So it is a bit messy and I am thinking about best practices to organize this.

I can only assign the Device to an Area and not the entities, which is a bit annoying.

Before I jump in and start configuring automations and dashboards, I am really curious to get some thoughts from experienced HA users on what the best organizational approach would be. Is it OK for me to just jump in with all of these entities in the Omnilink device as it is, or is it better to encapsulate entities in some kind of virtual device (I don’t even know if that is possible) so that I can assign each device to an area?

Or is there another structural approach that would be most sensible? I am just asking because I’m worried that I go down the wrong rabbit hole and must retrace my steps later.

I would at least change the area for the different entities.
This is possible in the settings for the entity: at the bottom, turn off the switch named “use device area” and you will be allowed to change the area for your entity :slight_smile:

Wow! I did not know this is possible! Thank you so much. Super useful.
