This seems like the perfect scam for Lemmy for setting up a fresh IP for launching a cyber attack/scam with a real residential IP. Helping a community member while circumventing shitty corporations. (Not saying OP is, just that it would be a decent scam)
This requires either an insane amount of trust in a random person or gullibility. Plugging a random mailed device into your network, even behind a VLAN.
I definitely would never do this if I didn’t have absolute full and complete access to every part of the pi’s software, or preferably set it up myself (optionally in collaboration with the requester) and the requester only had read-only access to it.

This is also why open source wearables can’t have the best PPG heart rate/SPO2 tracking.
There are only about 4 PPG analog front ends still in production that don’t require an NDA and the Max86141 is the only one worth anything it seems.
You can’t do analog front ends with any small FPGAs that I know of and it is simply to large to do it (well, at least) on a small wearable with discrete components.
