Sonoff Basic and BME280

This feature is included only in tasmota-sensors.bin

"BME280 sensor, an environmental sensor with temperature, barometric pressure and humidity", see Datasheet.

"tasmota-sensors.bin is needed for this to work. tasmota.bin and tasmota-lite.bin do not include the necessary driver."

Connect BME280 to Sonoff-Basic based on the GPIO locations~

  • BME280-3.3V -> Sonoff-3.3V
  • BME280-GND -> Sonoff-GND
  • BME280-SCL -> Sonoff-TX
  • BME280-SDA -> Sonoff-RX

Wiring BME280 with Sonoff BASIC

NOTE:
YOU NEED TO DISABLE SERIAL LOG COMPLETELY TO ALLOW SENSORS ON TX/RX PINS

On the Tasmota web interface go to Configuration->Configure Module and set
