OK, works not. I had to reboot after adding the user to the group.
But weewx doesn't recognize the sensor. In the webinterface inside temp is
17° but acually it's 26°. I have this in syslog
*Aug 15 15:09:50 weather weewxd[608]: CRITICAL __main__: **** File
"/etc/weewx/bin/user/bme280wx.py", line 58, in __init__Aug 15 15:10:00
weather weewxd.py[608]: bme280: bme280wx configuration {'i2c_port': '1',
'i2c_address': '0x76', 'usUnits': 'US', 'temperatureKeys': 'inTemp',
'temperature_must_have': '', 'pressureKeys': 'pressure',
'pressure_must_have': 'outTemp', 'humidityKeys': 'inHumidity',
'humidity_must_have': ''}*
Your driver is for *waveshare* bme280 but I thought it's from bosch. Is it
possible we are talking about different sensors?
