Consider LibreVAC under firmware
I was looking into robotic vacuum cleaners and apparently by default those devices are quite up to par with any other marvels of IOT, calling home, sending unnecessary private data back. Fortunately there seems to be some sort of open source attempt called LibreRVAC:
The goal of this project is to create a free/libre/open-source firmware for robotic vacuum cleaners.
Thus the idea for possibly new category (IOT Household appliances/Robotic vacuum cleaners), but I guess it could fit into firmware as well.
