The project where I had to write to flash? This was a network connected temperature and humidity sensor for a store room which had a built-in OLED display but was also network connected and hosted a website for graphing data output and displaying historical and real-time data. I wrote to flash so I could update the web page and other data OTA which was too big to fit in RAM or EEPROM and I didn't want to store on the SD card in case it was removed for any reason. It wasn't MySensors connected, unfortunately :)

TY, for link and this article, I have some interesting ideas now)

Excellent, thanks, just what I needed to know :)

Hi @TheoL how is life and hacking? :) I got reminded on this topic when I saw that Domoticz now officially supports the MySensors MQTT Gateway So I was thinking maybe you have some time and material to contribute to the subject, I see there is a lot of people (me first) not really understanding how they could benefit from MQTT protocol. Since you mentioned the presentation/tutorial last time :) Cheers!

Hi! If the radio doesnt sleep you will consume pretty much power and have to change batteries often. Option 2 is better if you dont need instant changes on the radiator.
