All in all, this turned out to be less useful than I’d hoped. I found a tile mate at the office we’d received a Christmas Gift from an old vendor so I took it home and attached it to my dog. He gets picked up by one of the Google Homes we have from time to time but generally he’s not found by any of them, even though he actually spends ~80% of his time very close to either the Home Mini we have in the bedroom, or the Home we have in the kitchen.
It’s a similar story for my phone, which is in the bedroom with me (orange) all through the night but mostly shows up as not being found (purple).
I’m definitely interested if anyone has any tips and tricks. For now I’m just glad that I stole the tile I’m using rather than paying for it
