Request - BME280 support #23

Closed smadds closed 7 years ago

smadds commented 7 years ago

I know space is tight, but I'm hoping to standardise on the BME280 temperature/humidity/pressure sensor. Is there any possibility of adding I2C support for it in Tasmota?

(Adafruit seems to be the most popular library, or this cactus.io one more stand-alone)

The BME280 is already supported

OK thanks @jaysuk. I was mistakenly looking for it in the list of sensor options. Do you know how to access it? Does allocating SCL and SDA pins enable a search for sensors?

jaysuk commented 7 years ago

yes, that should be sufficient.

For some I2C devices power cycling of sonoff is needed.

I am compiling Tasmota to add support for the seven segment display and I want to use the BME280 sensor but it wont load drivers. I have tried #define USE_BME280 in the user override but it won't load. i2cscan finds the sensor. can I include the driver when compiling on my own? I can't use the sensor bin because it doesn't include my display driver.

Thanks

Never mind I found the reference in the my_user_config to USE_BMP all working now.

Thanks you
