Sonoff Th16 and external button
Posted: Tue May 21, 2019 3:23 pmHi.
I want to put a Sonoff Th16 with a external button in a box. When i press the button, i want to have access to the portal of Wifimanager to put a new password. Is this possible? This is the code that i want to use. Thanks for your help!
