Failed to open the i2c bus
Posted: Tuesday 30 January 2018 17:35
HI,
I would like to use my BME280 sensor. This sensor uses the I2C bus.
In settings => Hardware
I add a I2C sensor type ans I2C sensor BME280 as subtype.
and connect SDA, SCL, Vcc & GND pin
In the log I have
But every minutes
Why this bus is undefined ?
When I test this sensor with a python script, all is ok. I got tmp, Hum & baro correctly.
For info, I use Domoticz beta 3.8872 and a RPI3
What's wrong with domoticz ??
