Hi,

I’ve been attempting a similar task but with ESP8266 which has the Wifi/Ethernet connectivity. A couple of years I had a simple text based protocol pushing data to StreamDevice and it still works fine, but not the most elegant solution. mqtt protocol seems more suited for not-always-on devices and most importantly, it’s readily available in Arduino library stack. While there are other ways to interact with mqtt, EPICS has been my daily job which for me it makes it obvious choice for a home control system. There has been some development towards mqtt in the past (https://accelconf.web.cern.ch/icalepcs2017/papers/thpha198.pdf) and I believe some lab might actually be using mqtt. But I couldn’t find the code and instead wanted to learn a bit about mqtt myself by prototyping mqtt-epics device driver. The project is still in very early stages and nothing is on GitHub yet. If there’s interest I could push my WIP to GitHub soon.
