Easy access to 3 modes of operation

Unlike the previous version of the Sonoff 4CHR2 switch, we have access to Self-locking modes (allows you to switch on devices that remain on until they are manually switched off), interlock (when you switch on the second device, the other, previously switched on is automatically switched off) and inching (when you switch on the device is switched off after a predetermined time) directly through the application on your phone.

SThe self-locking mode allows you to immediately switch on/off the 4 connected light sources.
