I’ve followed some instructions around, i.e.created files:
‘/mnt/boot/config.txt’
with entry:
dtparam=i2c1=on
dtparam=i2c_arm=on
And /etc/modules-load.d/rpi-i2c.conf’’ with:
i2c-bcm2708
i2c-dev
Also with ‘/config/configuration.yaml’ with:
# Temperature/humidity/pressure
- platform: bme280
name: THP sensor
i2c_address: 0x77
operation_mode: 2 # forced mode
time_standby: 5
oversampling_temperature: 4
oversampling_pressure: 4
oversampling_humidity: 4
delta_temperature: -0.5
monitored_conditions:
- temperature
- humidity
- pressure
scan_interval: 40
But I’m getting errors:
Error while setting up platform bme280

During handling of the above exception, another exception occurred:

Not sure what I should do next.
