In switches Livolo has modern electronics installed, which automatically turns off when a short circuit or open circuit is detected. Please check the wiring. Perhaps there was a short circuit there.
To check the functionality of the switches, you can connect them separately.
If the switches were initially functioning normally but then started turning on and off spontaneously, consider what you recently connected. This may be due to the additional lighting. Try turning it off and check the operation of the switches.
Perhaps the problem is in the transformer?
Very often the reason for spontaneous switching on/off is the connection of an LED strip with a 220-12/24 V transformer.
The transformer does not have to be connected to a switch that turns itself on and off. It may be connected to one of the lines of a two-key switch, and the other key may not operate reliably. Or it can be installed in another room, for example, in the kitchen, and the switches in the next room can turn on and off spontaneously because they are connected to the same phase.
Try turning off the transformer. If the problem goes away, then the transformer may need to be replaced.
