Yeah, that makes sense. We are lucky in that we get to deploy our code to the devices. It’s not really “embedded” in the sense most people use as these are essentially sandboxed Linux devices that only run applications written in a programming language specific to these devices which is similar to Lua/python but the scripts get turned into byte code at boot IIRC, but none the less very powerful/fast.

You work on BMS stuff? That’s cool- a little bit outside my domain (I do energy modeling research for buildings) but have been to some fun talks semi-recently about BMs/BAS/telemetry in buildings etc. The whole landscape seems like a real mess there.

FYI that podcast I linked has some interesting discussion about some issues with PTP over NTP- worth listening to for sure.
