Error: BME280 Not Initalized #7

Closed theGeorg closed 6 years ago

theGeorg commented 6 years ago

Homebridge is loading and everything is running but every time the data of the sensor is polled (every minute) I get the message

[Date] [Sensor] Error: BME280 Not Initalized

Sensor is working fine using for example this script.

Any idea?

NorthernMan54 commented 6 years ago

I’m wondering if it’s this

Since bme280-sensor needs to talk directly to the I2C bus and requires access to /dev/i2c, you will typically need run Node with elevated privileges or add your user account to the i2c group: $ sudo adduser $USER i2c

@NorthernMan54 Thanks for the reply.

I have done $ sudo adduser $USER i2c for my pi and homebridge accounts.

How do I run Node with elevated privileges?

When I start up homebridge I get this error message:

You shouldn’t need to. In my environment I run it with normal permissions

Looking at that message, and it looks like the install had failed.

Try this

1) Remove homebridge-bme280

sudo rm -rf /usr/local/lib/node_modules/homebridge-bme280

2) Reinstall homebridge-bme280, I presume you used the version from Instructables

sudo su sudo npm install -g https://github.com/NorthernMan54/homebridge-bme280

Try that and if you get an error from the install please share.

Okay, you must be on the recent version of npm/nodejs

Try this

sudo rm -rf /usr/local/lib/node_modules/homebridge-bme280

sudo su sudo npm install -g —unsafe-perm https://github.com/NorthernMan54/homebridge-bme280 https://github.com/NorthernMan54/homebridge-bme280

Running into a similar issue! I am installing plugins in homebridge-ui in the browser. Does this mean I should remove the plugin there and install it again over the terminal with root privileges?
