I mostly agree. But on second thought, you can pack a lot of encoded data into 192 bytes. Say you had like 20 cameras all hooked up to a local server doing local ML object detection and running Home Assistant monitoring a bunch of binary sensors (doors, flood, motion). You could then have 1 bit be a flag for your top 100 objects and 92 binary sensors and get 25 reports of what's going on per day. Could be useful for remote cottage monitoring or something.

I guess if you have enough power to run a ML server, cameras, and remote sensors, you probably have normal internet though, eh?

bits != bytes. There’s room for 8 times that ;)

OH DANG! Nice. Psh yeah you can run a whole facility operation off that kind of bandwidth.

You can probably do a lot better than your estimation with some clever coding schemes.

Your scheme is only optimal if each flag has an independent 50% chance of being set or unset.

See https://en.wikipedia.org/wiki/Succinct_data_structure for some examples.

Depends how many seconds per day you use them :)

I'm imagining a small, lone device mounted to a post somewhere in the wilderness. Probably solar powered.

This could work for alerting/notifications in such a case.

A larger sensor array installation probably has enough power and space available for better options.
