In that project Nodemcu ESP8266 D0 Pin work as momentary type means in-app we write how many times pin will be done ON/OFF and That ON/OFF time(Delay time) we set in Nodemcu Code not in the app
D1 to D8 Pins use as Normal On/Off type means in-app Both Button (On/Off) shows if user click in ON of D1 button then D1 will be ON(means pulse ON in D1 Pin). If the user set in ON button and later if we power OFF of Nodemcu and when Power On then still D1 pin is high, and that pin status also shows in app.
Same thing happen with rest of pins (D2 to D8)
That Nodemcu is set with any wifi just pressing Flash button.
In App no limit of add nodemcu means user can and many nodemcu in app.
We can easy to edit/delete of any nodemcu in app, Edit means we rename of any nodemcu.
In app want auto and manual way any nodemcu.
