@Dmitriy Thanks for your reply. I looked at that example but I can’t fully understand it. I linked the tmp36 sensor to the digital pin 5 and loaded your example (after installing SimpleTimer library and changed my token) but the app keep saying “arduino uno is offline” and socat keep quitting and “reconnecting in 3s…” due to “inactivity timeout triggered”.
Does this mean the code is wrong? Shouldn’t the code include a conversion for celsius degree?
I’m struggling to make it work. Please help!
