    Yes... i understand your point...

    BUT

    If all nodes could speak MQTT, why not to use this language and let them speak to controler (if to far away over the gateway, which is acting like a repeater)...

    I did ask it, because i wanted to use sketches from mysensors combining with the (translator) GW, so i can use both (sensor node + GW) in one Box (Arduino MEGA + W5100 shield). An elt this "box" send the data via ethernet to controller using MQTT protokoll, which is the state of the art.

      you mean, no nrf module? whats the sense in using the mysensors lib? thats the "main" task (imho): creating a sensor mesh via the nrf module and channeling everthing via the gateway?

      @dakky

      you are already using mega R3 as an client... which "language" are you using to speak to RPI? Which Broker are you using?

      did you try ioBROKER?

        and how to you want to transmit any data from the nodes to your network? Wired? cables everywhere? wlan? no low power/battery + expensive in relation to the cheap nrf modules.

        my gateway is conencted to the RPI via w5100 ethernet shield. My mqtt broker is mosquitto. simply and functional :D

          so your setup is following ?

          arduino Sensor node with nrf <----> arduino MEGA as GW with w5100 <--> RPI with a "server/Broker"

          right?

              yep, exactly

              edit: have a look in the development branch of mysensors. There is a w5100Clientgateway example. I simply changed the pins for the mega and thats it.

                        Not sure exactly what are you looking for...

                        See if this post helps with the pins.

                        Cheers
