Flashing Shelly device OTA without serial connection

Any Shelly devices can be reflashed to the latest Tasmota OTA without physical connection with the help of mgos-to-tasmota.

Your Shelly device must be connected to your Wifi, configured with gateway and DNS and have access to the Internet. Be sure to have a reliable power connection as well as a reliable Wifi connection. Power or Wifi loss will make your device unresponsive and recovery will go through serial flashing.

  • Open a web browser to your Shelly device
  • In the address bar of your browser type the following :
    replace shellyip with the actual IP address of your Shelly.

After flashing, which can take a few minutes, the Shelly device will restart with lastest Tasmota and create an AP tasmota-XXXXX. From there follow standard configuration procedure. Don’t forget to enter the template at the end of the configuration.
