Anyone working on decoding Kidde Smoke Detectors

[Cyn]

Just ordered a Kidde RF-SM-DC and want to get it talking with Home Assistant via MQTT

Was wondering if anyone else has decoded this device

Thanks

Hi Cyn, I have this detector and will be looking at it over the holidays.   DId you find out the codes already?  If so, please share, if not, I wlll let you know what I find.

I found some information concerning the communications.  Sadly, I do not have a 433mhz receiver in my box - must have given it away.   I ordered one from China so in about 6 weeks I can test.

Here is the link:

https://patents.google.com/patent/US7339468

It describes the manchester encoding, and message content.

On an arduino site I found:

http://forum.arduino.cc/index.php?topic=233552.0

With this information, it should be fairly easy to figure out.

Hope this helps.
