Basically all those nRF5x products are Arduino compatible AirTags with a battery included. IIRC they also have an imprecise but low power, chip integral temperature gauge. Maybe a wireless interval thermometer might be a good start?

Yea I saw somewhere airtags are just Nordic chips? Kind of surprised because the airpod w1/h1 chips aren’t

I would guess either better margins or better low power performance for better battery longevity in the nRF 52.
