    I don't get the buttonPin array thing at all?

    Why not just:
    pinMode(i + FIRST_PIN, INPUT_PULLUP);

    @hek if the array was initialized, it could be used to set arbitrary pins. So pin 4,5,6,7,8,A0,A1,A2,A3 could be used for example (to avoid conflicts with the standard nrf24 wiring but still allow a lot of buttons). But as you mentioned before, without initializing the array the behavior will be strange.

      Big Thanks!
      I have changed all array parts in setup in the same manner like above and it works :-)

        Hi,
        Here is a sketch for multi buttons (no relays, no repeated parts of code for each buttons) just enter number of buttons and first digital pin where buttons are attached.
        Thanks to @hek for help...

        /**
           The MySensors Arduino library handles the wireless radio link and protocol

           The sensors forms a self healing radio network with optional repeaters. Each
           repeater and gateway builds a routing tables in EEPROM which keeps track of the
           network topology allowing messages to be routed to nodes.

          Could these reed switches be used in the NC configuration for door/window sensor to save more battery?

            yes exactly.
            i made a nrf5 board using this principle.

              did you use those with 3 pins?

                yes no-nc reed, connect them to IOs of your mcu and switch between input and output

                  I use them, with one wire connected to each interrupt pin (I only activate the one that's not connected) and they work fine.
                  Else you can cheat with a basic reed switch, you just need an additional magnet on the other side of your switch that's weaker than the door magnet, and turn your reed 180°.
                  You make the weak magnet close the reed when door is opened and far from the strong door magnet. When you close the door the strong magnet will open the reed switch.

                    given the low price, I think it is not worth the extra work to "mod" the normal reed switches :D

                      I'd like to go even simpler:

                      • Window is closed - magnet pulls reed switch so that no power flows to the NRF5.
                      • Window is opened - The NRF5 now gets power, boots, connects to the MySensors network, and sends a "window is open" message every 10 minutes.
                      • Window is closed again - NRF5 loses power.

                      Seems to me that this would be quite energy efficient?

                      Perhaps build it into this case:

                      (runs on 2 AAA batteries)

                        I would say this technique is efficient depending on the usecase.
                        For example, for basic ambiant sensors not needing any security why not. On other side, for main doors which could benefit security, I prefer to use hearbeat with less interval time, so it's possible to know if the sensor is offline. else controller wouldn't know this if the sensor only update when door state change.

                          Totally true.

                          I was wondering what the state of Attiny85 support is. For absolute beginners (in workshops) it might be easier to connect the radio to a digispark.

                          // cancel that. It could never support encryption.

                            I have some troubles with this device.
                            Sometimes it does not respond to the first click, sometimes it remains switched on after first click until second click

                            When I press the button once - I see the LED on my gateway blinks always 3 times
                            1 RX TX
                            2 RX ERR
                            3 RX ERR

                            Device powered with CR2032 and running on 1Mhz@1.8V (internal clock)
                            Button input pulled to GND with resistor 47K and waking up if VCC connected through the button
                            Also have a 10uF tantal capacitor on power supply pins +several 0,1uF ceramic capacitors

                            Actually I dont know how to debug/log my gateway messages on Linux

                              Uncomment the my_debug and you should see all the debug info.

                                    Every line was shifted to the right side and finally no space left.
