I recently needed to change the Wifi password for a Sonoff smart plug running the Tasmota firmware (which I had flashed on previously).
The Wifi data (SSID, password) can be set during flashing but I did not want to through that whole process again.
The internet is full of useless and contradicting (long press, 4-presses, ...) information about how to reset a Tasmota-flashed Sonoff smart plug, so I wrote down what worked for me.
The reason for all that contradicting statements is probably that this has changed
8.3.0 (see here) and 6 short presses
are required to reset the device since then.
Note: Since version
8.3.0a reset requires 6 short presses.
From there on it's straight-forward:
- The Sonoff device opens a network with an SSID starting with
- Joining that network, the SSID and password for the actual Wifi network can be configured.
