Ecolink Firefighter - working with hass.io?

Well I found that when I hold the test button for longer, I get the alert on the 3rd or so beep from the smoke detector… So that’s awesome.

But I’m still not sure how to get CO alerts… It may not be something that’s possible in my situation. I have a CO detector outside of the room where the firefighter is located. I guess it just listens for a different tone? Not sure if it’ll hear it since it states that the alarms need to be maximum 6" away. If anyone has insight on this I’d appreciate it.

Thanks!
