  • Hi, I made a little project to controll garage door and it turned out pretty complicated problem for me. I have successfull control of those garage motor with two different setups, one with RF reciever and another with wifi via Shelly. They work pretty well unless i join them both to the garage motor. Shelly then works fine, but the range RF reciever went from 150 meters to 5 meters. I though RF reciever is distrubted by wifi of Shelly, but when wifi is turned off on shelly then the range is still low, unless i unplug shelly from source of power. How it would be posiible to make RF reciever back to higher erange? How is shelly even capable of interference the RF 433 MHz?

    Most likely the RF receiver is disturbed by the primary step down converter of Shelly’s power supply. Try to power the Shelly with 12V DC!
