    MyMessage msg(0,V_TRIPPED);

    So I need to call MyMessage twice. one for each sensor ID? How do I do that without making two instances? That is kind of what I have been trying to do, but I'm having trouble with the syntax.

      @BulldogLowell Thank you! It finally works! I'll make a sketch with comments so other people can use it later for reference.

        @algoritm

        OK, but we should be able to do it with the sleep/wake returning the interrupt number and executing only the pin change on one child... I have to play with that if I can get this rigged.

            How about 3 doorsensors? Just +1 on everything?

              there are two external interrupts on most Arduino... but Mega has six.
              so yes, you can extend the code above if you have the right hardware.

              but... @hek 's library may not support more than two.

                You could make an or gate, with a couple of diodes, then you only only need 1 interrupt pin. If you need to check which one of the reed switches was triggered, you could wire each of them to a separate input on the arduino as well as the input to the or gate.

                    Ok, need to have one of these to play with myself.

                    We should probably have an example of using it distributed with the MySensors library. Might steal something from the code posted here.

                      @hek They are great and very cheap. Just make sure you get the latest version of the board (the one with the micro-usb). 10pcs for $7 on Ebay.

                        But the one you linked didn't have any I2C interface. How about this?

                          @hek The TP4056 is the charger module. I didn't know you meant the fuel gauge. They are two separate boards which I solder together to one part. :)
