Signing might be doable like that but it all depends on the size of the data that you're pushing. if it's a long string of readings that might not be so easy

Signing might be doable like that but it all depends on the size of the data that you're pushing. if it's a long string of readings that might not be so easy since you might not be able to fit everything in memory still (These devices routinely have <4k of ram). Might be doable to go byte by byte as you build the message and output it. It's certainly a challenging problem.
