Help decode unknown rf remote

Need some help to decode this rf remote for a wall panel light switch so that i can control it with esp8266. My setup is a esp8266 NodeMCU board + rf receiver. I can verify the receiver is functioning with other rf remotes but nothing is being read in the serial monitor with this one. I open up the remote but have no clues on what kind of chip or protocol it is. I like this switch because it has dedicated on/off, but if I have no success I may try the livolo switch. Thanks.

Please ask that on a ESP8266 forum. Your setup does not involve an Arduino in any way.

I use the methods described in this blog to decode RF remotes.

You will need a receiver set to the appropriate frequency, and a laptop running Audacity.
