Grove AI Hat, edge computing in your hands

The industry has been talking about edge computing for some time now. The idea is to distribute the data storage and intelligence in locations closer to where they are needed and only use external services when absolutely necessary. Centralized cloud services have a series of drawbacks for the IIoT world, being maybe latency and security the bigger ones. Some (a lot of?) companies do not want their data to go outside their facilities and critical systems cannot rely on Internet connection....

Sonoff B1, lights and shades

My previous post about adding a custom RF module to a Sonoff HT got some visibility as it was published at hackaday....
