Re: First Alert Wireless Smoke & Fire Alarm (ZSMOKE/ZCOMBO)

Costco has these on sale as a 3-Pack until 5/26/2022 for $80 (item: 1335046)

I'm still using Indigo 2012.2 and have configured three (3) of these to match the RAW packets received, thanks for that Matt. I even went as far to test with some Smoke Detector Tester Spray, just to be 100% sure they were configured correctly.

As I read thru this thread again, the PDF shared suggested that CO Alarms can be distinguished from Fire Alarms with:

Command Class
Notification (0x71)

Notification Type
CO(0x02)

Notification Event
0x02

Would the following catch a CO Alarm based on that?

Code: Select all
* 0x71 0x05 0x00 0x00 0x00 0xFF 0x02 0x02 *

It will be that, or possibly this:

Code: Select all
* 0x71 0x05 0x00 0x00 0x00 0xFF 0x02 0x01 *

So you could create Triggers for both just to be safe. I'd recommend using Indigo 2022.1 since it has a device definition and will create a CO Alarm on/off device you can directly Trigger off of. Its device definition sets the state to ON for either 0x02 0x01 or 0x02 0x02.
