Hi @user130,
This isn’t the learn button we’re referring to. The learn button is on the back of the opener motor (near the wiring terminals) and is square yellow on this model. It’s kinda a weird hybrid of Security+ and Security+ 2.0, but it works. There’s a thread more specifically for this model/variant here: Issue thread (GDO blaq): Chamberlain RJO20 / LiftMaster 8500 / square yellow button
The wall button console is not a wireless remote control. It communicates with the garage opener over a serial data connection over the red and white wires (which also provide 12V DC power). The konnected device taps into this circuit and communicates to the garage opener on the circuit in the same way. It’s almost like magic, yes!
