Hello, I am trying to develop a Project based on @XorAndOr Project (https://www.b4x.com/android/forum/threads/home-control-4.148024/) adding an extra functionality. I whish that when somebody press the ring button, a notification arrive to my B4A App but I have a problem.
When I press the ring button, the notification arrive but, sometimes I recieve some notification without anybody press the button. It is due to a floating signal.
Some memers of our forum say to me that I have to read information about Pull-up and Pull-down resistors. After that, I have implemented this solutions on my board Esp8266 and I got two results:

- Relays doors does not work.
- nothing happen. I recieve the notification, but sometimes recieve notification without anybody press the ring button.
- My original diagram with out notification system (only the relays doors)
- My original diagram connected to notification system without resistors (I recieve the notification, but sometimes recieve notification without anybody press the ring button.
- My original diagram with pull-up resistor (does not work and the relays do not work now)
- My original diagrma with pull-down resistor (does not work and the relays do not work now)
