I noticed that there was a lot of traffic in the air on the 433Mhz band, so I tried to find the source of these messages.
Using my trusted RFXCom receiver and Rfreceiver, I was able to identity most of the messages as coming from Oregon Scientific sensors in the neighborhood, but still there are a few that show as an empty line in the RFreceiver interface.
They arrive in bursts of 3 messages, with appr 30 seconds interval.
I can of course ignore them, but that would leave me curious about the origin.
Can someone tell me what the source of these messages is? And perhaps drop me a line on how to decode them?
