Every other transmit from FT020T (Outdoor weather station) sends duplicated data.
I do not see this on the F016TH (indoor temp/humid sensors).
Running in terminal the command “rtl_433 -F csv -R 146” I see that on every other transmission the data is duplicated. Normally the transmissions are around 16 seconds apart. However, on the dups data it is sent right away with same time stamp and at the same time, or better to say, same transmission block. See file CSV.png, I’ve marked in yellow the dups with the same timestamp and done as one transmission block.
In looking at an SDR waterfall output, I can see that every other transmission block appears to have extra data sent. See file SDRoutput.png. I’ve put the duplicate and single transmissions side by side. The left side shows the duplicate data sent. The right side shows the single data. You can see the left side of the image is larger and longer in time.
Batteries are good and I’ve done resets on the FT020T.
I can code out the extra data. But does anyone know why I’m seeing this.
Regards
