hello, I got your sonoff basic with tasmota. How can I rest it to factory defaults ? thank you Nicola


On delivery it is already in factory reset state.

If you want to factory reset afterwords, check this link Tasmota Button Usage

Long press

When held continuously for 40 seconds (Configurable with SetOption32, value is 10x the configured hold time) Tasmota will reset to firmware defaults and restart.
