Openwrt Luci device tracker to Entity with unique id?

I am trying to monitor when computers are on or off in my house.

How do I simply create an entity from an Openwrt Luci device tracker entity as they do not have unique ids?

My current workaround is to make a bogus Person with the computer device from Openwrt Luci as the Track Device.

I’ve read I can do something with mqtt but I would prefer something simple if possible.

A template sensor to mirror the state of the Openwrt Luci entity? You could then give that a unique_id.

Thanks. That seems to work.
I made a Helper \ Template binary sensor with the State template as:
{{ is_state(‘device_tracker.pc’, ‘home’) }}
with a Running device class.
