Samsung Smart Aircon and MRTG

We’ve had 4 Samsung Smart air conditioners for a few years and every once and a while I revisit trying to automate them using scripts and a like. This time I was successfull using perl scripts written/edited by Daniel (CloCkWeRX) and Shannon (freman) to deal with the transmission protocol and token management – I personally would’ve never been able to work it out – so thanks and full credit to them. To start with, you have to discover then register the aircons to get a token for each, to discover them you can use this script get_samsung.pl, which was obtained Continue Reading →

ESP8266 – Work in progress

After a few weeks of trial and error, it’s some what stable, but still has it’s issues every couple of hours. To get around this, I’ve incorporated a hard reset after ‘x’ amount of program loops with an Arduino. I had a status check that ran instead of loops, but the output of the SoC wasn’t synchronous, when dealing with multiple events from the UART and wifi Continue Reading →
