Anyone decoded KTNNKG 433MHz RF Remote Control EV1527

[Kevin Saye]

I have decoded items in the past but can't decode " KTNNKG 433MHz RF Remote Control EV1527"

I have purchased: https://www.banggood.com/KTNNKG-433MHz-RF-Remote-Control-EV1527-1-or-2-or-3-or-4-Buttons-Learning-Model-Wireless-Transmitter-For-Smart-Light-Switch-p-1618440.html

My process was:

1. disconnect the antenna
2. run rtl_433 -S all
3. click the button a few times and I only see:

rtl_433 version 21.12-60-g5f0ff6db branch master at 202202121409 inputs file rtl_tcp RTL-SDR with TLS

Use -h for usage help and see https://triq.org/ for documentation.

Any suggestions?

Try different center frequency and perhaps higher sample rate.

But may just be to noisy.
