I have used a combination of Homebridge and the homebridge-google-nest plugin to allow a Nest Protect detector to be accessible in Home Assistant. It appears that both sensors are available in Home Assistant. However, I cannot identify which is CO and which is smoke. In Homebridge itself, they are defined correctly and the only differences in settings values are the iid value.
This does not appear as a value in Home Assistant so i cannot tell which is which. Any ideas?
