I am sending a 433MHz signal from the remote to two devices, and both devices are not executing commands. The video shows that both devices receive a signal from the remote. Left of the left button, right of the right. A red diode lights up on each device, which means that a signal has been received. But the devices themselves refuse to work correctly. The command is executed in 1 out of 10 cases. You have to send a command 10 times to execute it 1 time.
Later, I will give a technical support response in the description of this video here.
