This wall transmitter contains, see the picture below, amazingly little electronics. What is immediately noticeable is that there is space on the PCB for three print switches, of which only the middle one is present. A handyman can therefore make a three-channel transmitter from this single-channel transmitter with some soldering work. The large transmitting antenna that fills approximately half of the print surface provides a wide range or 25 m. The only chip on the PCB is an eV1527 and when you look up the datasheet of this IC it appears that this chip is internally programmed on one out of a total of 1,048,576 address codes. After transmitting this 20-bit wide address code, the switch transmits four data bits.

This sonoff wireless transmitter wall button is superb but should be little smaller in size and also little light like sonoff device small green light always on should have been there for night time. Otherwise it is just wonderful.
