    Hi!

    1. I primary use 4,7uF and are tested higher and two caps paralell on my gateway atm.

    I can ACK this:
    On the Gateway i need 2 caps: 100uF and 4.7uF. without the 100uF cap I had some really strange behavior when starting the gateway until the communication got established same (random) times
    At the nodes 4.7uF is sufficent.

    Controller: Raspberry Pi 2 :: Openhab2 :: with @TimO MySensors Binding
    Gateway: Arduino MEGA 2560 R3 :: W5100 :: Ethernet GW

      Thanks a lot for your answers. I have installed the caps and both the node and gateway are initiated every time flawless but they refuse to communicate to each other. The modules are recognized as being '+' versions using the GetStated sketch from the RF24library. Tried to setup both uno's in different ways (pingpong; serial gateway and sensor) but none of the combinations shows any way of communication between the two boards. I have been struggling for three days now; I am out of ideas and I am afraid it's a problem with the nRF modules (see this link also ) . I will try to order some new ones.....

        How far from eachother do you have the nodes?

          @sundberg84 : in the same room. One on the serial monitor, one in an external power supply

            After a steep learning curve I found out that one of my UNO clones was not able to receive messages in any way. I have now made a sensor based on a pro mini which works fine with a serial gateway. The only problems I still encounter is that the node-ID is not assigned automatically but I solved it by defining it in the sketch. @sundberg84 : I saw a different post of you for the Easy/Newbie PCB for MySensors. It looks very tempting to start using them !

              openhab does not manage the IDs. it's simply not implemented on the openhab side

              Gateway: Arduino MEGA 2560 R3 :: W5100 :: Ethernet GW

                @dakky

                Do it have to be electrolyte cap or can it be SMD cap?

                      Can the SMD cap be like this?
