As part of a larger project, I would like to be able to replay signals of this remote. It's a remote for a temperature controller, operating at 433MHz and it looks like it's using ASK modulation.
I've bought an RTL-SDR dongle and recorded the remote signal using SDRSharp (see Audacity screenshots). Each button press (increase/decrease temperature) produces 6 packets that are exactly the same.
From reading a few blogs it seems that the common assumption is that each fat/thin pulse corresponds to 0/1. Is that a reasonable assumption? Also, do I need to replay all 6 packets and does the interval between the packets matter? Any sense in how accurate my timing (ie baud rate) needs to be?
