Trying to set this up: https://home-assistant.io/components/sensor.serial_pm/
My config: sensor:
-
platform: serial_pm
serial_device: /dev/ttyUSB0
name: Air Quality
brand: plantower,pms5003
When hass.io starts up I get this error: read timeout after 2 seconds, read 0 bytes
But when I then unplug and plug it back in the RX light on the USB to serial adapter starts flashing and I get this error:
Update for sensor.pm25 fails Traceback (most recent call last): File “/usr/lib/python3.6/site-packages/homeassistant/helpers/entity.py”, line 204, in asyncupdate_ha_state yield from self.async_device_update() File “/usr/lib/python3.6/site-packages/homeassistant/helpers/entity.py”, line 327, in async_device_update yield from self.hass.async_add_job(self.update) File “/usr/lib/python3.6/asyncio/futures.py”, line 332, in _iter yield self # This tells Task to wait for completion.

Any ideas? Thanks!
