Maybe one more thing...

I updated all Carbon Dioxide to Air Quality and CarbonDioxide to AirQuality and now I see this

[matt_k]

Thanks @thebearmay!
@toy4rick You can not change the capability to Air quality, that one has to be CarbonDioxide as Hubitat does not support Air Quality as a capability.

[toy4rick]

OK TY, that worked... So in Current States, I will always say Carbon Dioxide but it will be used as an Air Quality value

Thanks again
Rick

Edit: Wait, now I see an Air Quality in Current States along with a CD

[thebearmay]

Couldn't use it as a capability, but the attribute name could change if the capability wasn't declared. Similar to using the Actuator capability to cover a need for generic attributes. Big thing is that you are now getting the values in a useful manner.

[toy4rick]

Since HE doesn't see it as an Air Quality device but as either a CD/CO/Temp device, how can I trigger off the AQ value? Tried using a custom attribute but no luck

Edit: Is this something the HE team needs to enable? @mike.maxwell

[thebearmay]

Looks like you should still be able to click you carbonDioxide attribute

[toy4rick]

Yes been trying that however it's not tied to the AQ value so it won't trigger a test rule

Nothing in the logs for this rule yet AQ value changes are being recorded in the device events page

What am I missing?

[thebearmay]

Looks like it should work, but RM isn't my regular rule engine.

[toy4rick]

@mike.maxwell any thoughts on how I can get access to the Air Quality value to use in RM?

Thanks

[thebearmay]

Easiest way might be to declare an attribute entry named carbonDioxide right under the one called firmware. This should make the attribute discoverable by RM.

attribute “carbonDioxide”, ”number”

[toy4rick]

Thanks for the tip

In this case, this device is not a Co2 sensor but an air quality sensor
The Air Quality value is being displayed by the driver but no way to use it in RM, at least that I can find so far

Or maybe I'm just not understanding

[thebearmay]

Same idea:

attribute “airQuality”, “number”

(might want to do the same for humidty and temperature too)

If you don’t declare them they’re transient and RM can’t discover them.

[toy4rick]

TY very much, that was the trick

As I said, I'm not a developer so some times it takes a bit for me to catch on

Thanks again

You’re doing fine. We’ll have you writing your own apps within the year
