Raspberry Pi - GPIO / I2C

[piotruscilko]

Hi, I need nodes based on I2C, and GPIO comunication in node-red addon due to remove GPIO components from HASS core:

• node-red-contrib-dht-sensor (I have DHT22 sensor connected to raspberry GPIO16) - node-dht-sensor installed is reqired, but I cannot install it using standard command i HASS OS: answer for comand: "npm install node-dht-sensor" is: "-bash: npm: command not found" how can I install it to go forward?

• node-red-contrib-mcp23017 (I2C bus expansion board connected) - it require also to install: node.js and node-mcp23017 (the same situation as above),

• node-red-contrib-bme280-rpi (I2C bus expansion board connected) - result of run node: "Sensor Init failed ->Error: EPERM: operation not permitted, open '/dev/i2c-1'", how can I give it permissions?

Thanks in advance

This add-on has removed support for GPIO as well. If you need those nodes, this add-on isn't for you.

Sorry!

And if?
HassOS I2C Configurator
