What is the best option for a virtual device?

I have integrated several sensors via e.g. scrape or helper etc., for example, which evaluate (but do not control) my heat pump. I would like to assign these to a heat pump device.
I have seen that there is no option to create your own device, but what is the alternative? Labels or a script?

I found device tools: GitHub - EuleMitKeule/device-tools: A powerful custom Home Assistant integration that provides comprehensive device management capabilities, allowing users to modify device attributes, reorganize entities, create virtual devices, and merge multiple devices into unified configurations.

However, I’m still unsure whether I really want to install such a basic function via a third-party integration. Perhaps there is a (good) reason why HA Core doesn’t offer this itself.

Because there’s no benefits besides logical grouping that’s offered by a device and ha long has pointed folks at integrations or entities… Even in Assist devices aren’t even exposed to the llm.

Its basically :
Theres things I’d think are core that should be there as well. And some other person agreed and wrote something to do a thing…

No more no less.

There are lots of “virtual” device options. Go to Settings → Devices → Helpers and Create Helper.

Op is talking about binding a group of helpers onto a synthetic ‘device’ not creating helpers themselves.

But that’s already an advantage ;). If there’s no advantage, then why are there devices at all? All other sensors can function without them.

I just don’t see any reason why devices and their assignment should only exist for integrations.
