Configure defaults for your device and build only sonoff firmware (we don't need all variants)

build

dpavlin@nuc:/nuc/esp8266/Sonoff-Tasmota$ platformio run -e sonoff

flashing

connect IO0 to GND to get in bootloader

erase flash

Flashing sonoff doesn't work for me reliably if I don't erase flash first. I suspect that config area is corrupted or something similar.

Please note that 565472 is bigger than 512Kb which means that OTA update won't fit if firmware size isn't reduced.

Remove bridge from IO0 to GND and test module.

first powerup

open web, toggle relay

verify that voltage seems sane

Wifi > Hostname

Mqtt > Topic

other > friendly name (displayed on web UI)

Logging parameters > Telemetry period - 10 # report sensor status every 10 sec

open console, and read voltage at output:
