I found the reference on:
https://denglend.github.io/decode345/part2.html
to other transmissions.
They might be 2gig Technologies sensors. I have house full of them and I have found that:
frequency = 345MHz
Pulse width = 270us (approx)
Encoding = Manchester
Packet Structure = 8 bytes.
I have not tried to parse out the bits because I will just assign the 8 byte message to a particular action. For example:
Back Door Close =FF7FB5E6D200BB09.
When I "close the back door" it transmits that packet 6 times close together then pauses about 1 second and repeats the 6 packets.
Sometimes the message gets garbled. I believe other sensors "report" in now and then and conflict with each other. Most likely that is why the packets are sent 6 times, 1 second delay, then 6 more times. That should increase the probability that a packet gets through.
BTW I saw your post (link above) a few months ago and because of that I bought a dongle and RPi. I have been plunging forward ever since not knowing that you were advancing also. I feel like I am reinventing the wheel but I'll keep on my path.
