Then I had to play hours to figure out what did I do wrong (turned out that using “New line” on Arduino serial console is messing the code so I needed to choose “No line ending”). Wemos D1 Mini was the easiest choice since it’s small and easy to program.Īfter downloading Nickduino’s sketch I had to adapt it to the ESP8266 and change some lines. I decided to work with ESP8266 cause I wanted to control the blinds remotely. So I had to order from eBay some new SAW tooth resonator that operate on 433.42MHz.Īfter I got those, I just replaces the resonator on the module with the new. I had some 433 RF modules in my drawer but those are operating at 433.92 MHz So after some google-ing I found a great guy called Nickduino on Github and he wrote an Arduino sketch that emulates Somfy remote.Īnd the Somfy RTS protocol is explained here.īut in a nutshell, the remote is operating at 433.42 MHz and the modulation is ASK/OOK.
In the beginning I thought the remote is working on infrared but it turned out to be RF.
The remote control cost around for the basic version and it has 3 buttons: Up, Down and Stop.
Those blinds works on a system called Somfy which includes one remote. I recently moved to another apartment where I got motorized blinds. Controlling Somfy blinds with ESP8266 The Story Behind Somfy?
