Post: Hi I hope this post founds you well. I'm struggling to get IO PI Plus up and running with home assistant. I'm able to get it running independently, but wi hass some library issue apears that freezes i2c interface. Any hints on troubleshooting libraries would be great. Here is how to reproduce: I’m using the homes assistant configuration below. [pre][code]switch: - platform: mcp23017 i2c_address: 0x20 pins: 1: Light1 3: Light3 5: Light5 7: Light7 9: Light9 11: Light11 13: Light13 15: Light15[/code][/pre] Environment used: RPI 3 B+ IO PI Plus expander HomeAssitant 0.110.70 - installed into venv I2C configured After a fresh start i can found I2C addresses (displayed instantly <1s) (homeassistant) homeassistant@raspberrypi:/srv/homeassistant $ i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: – -- – -- – -- – -- – -- – -- – 10: – -- – -- – -- – -- – -- – -- – -- – -- 20: 20 21 – -- – -- – -- – -- – -- – -- – -- 30: – -- – -- – -- – -- – -- – -- – -- – -- 40: – -- – -- – -- – -- – -- – -- – -- – -- 50: – -- – -- – -- – -- – -- – -- – -- – -- 60: – -- – -- – -- – -- – - can also successfully run my test python script controlling IO PI Plus with a relay board. After starting ./hass from I2c pins are not detected and I get an error in the log.
