eufy Security by Anker SmartTrack Link (Black, 4-Pack), Android not Supported, Works with Apple Find My (iOS only), Key Finder, Bluetooth Tracker for Earbuds and Luggage, Phone Finder, Water Resistant

Sounds like a plan 👍 You can also mix it up with a eufy Security by Anker SmartTrack Link. I have one with an AT in my car 😉 First gen AirTags are cheaper nowadays, but this is significantly more cost effective for redundancy. At this price you’ll find other things you want to tag twice (or in your case, four times 🤣).

If you get one of these the speaker is very easy to remove. It also does not have UWB so it can't be located with precision tracking. https://www.amazon.com/eufy-SmartTrack-Supported-Bluetooth-Resistant/dp/B0BN86R2HC/
