Virtual device to group a number of sensors

Configuration
1

Hi, new to Home Assistant, but have a computer science background.

I have been slowly building up two homes with HA Greens, and have added a pimironi Enviroweather in each of them.
I have managed to follow various videos/post on how to use mqtt to get the data into HA and have a bunch of sensors all bringin in data.

What I would like to do is to have a device that houses all of those sensors.

I have searched to see if this is possible but am ending up finding info on how to group a bunch of similar senors to do things ike average out the values (i.e. taking multiple temps to give an avergae temp for an area).

What I want to do is simply house the various differnt sensors in a virtual device.

There is no master plan to this - it just feels neater to be able to reference them.

Is this possible?

HA does not really work with devices.
Use entities instead.

It is a common mistake to try and gather entities in devices, because you will be adviced again and again to not use them, but use the entities directly and your work is then just wasted.
If you ignore this advice and go on with using devices then you set yourself up for trouble down the road.

Read the cook book in the community guide forum section. It will have the full explanation to why devices are a bad idea.
