Sonoff Dual WiFi Wireless Smart Switch

Sonoff Dual WiFi Wireless Smart Switch

Product Review (submitted on May 17, 2017):
I just received two Sonoff Dual and flashed them with Sonoff-Tasmota, despite the lack of button on Gpio0 to ground (operation delicate).
They connect correctly with MQTT and can be easily managed producing lot of information.
Commands On, Off, Toggle and blink are OK.
Very interesting item.
Gpio4 is theoretically not used. But how to use-it for a sensor ?
