Sometimes we really oughta ask ourselves if we should do something just because we can.
But I think this is a product that probably shouldn't be allowed to exist as a standard SaaS/IoT product.
If this was a box I could hook up on my toilet that showed useful info on a screen locally - with zero network access... I'd consider buying.

People are really glib about the loss of control relying on someone else's computer brings.
between service enshittification, company death (out of business), privacy concerns, and ownership contention (do I own a device if a company keeps keys to the locks inside it and won't give them to me? I'd argue a solid and resounding "NO")... I don't want anything to do with most modern networked devices in the form of IoT.
