@Eawo If you look at the excellent original post from @mfalkvidd above:
The 3.3V power on the Raspberry Pi is rated for a maximum of 50mA. A regular NRF24L01+ only needs 15mA, but if you are using a power amplified version you might exceed what the Raspberry Pi can output. In that case, an external power supply might be required.
I don't believe that you will need to make any changes to code.
Answering my own question, this seems to be the way to go.
I don't know how I never found this before ..

and

Sorry if this has been answered but I have searched and not found anything.
I am quite new to MySensors but I have a slowly growing system of sensors, a serial gateway and Domoticz on a Raspberry Pi, all working fine.
I want to integrate my existing weather station which currently uses an Arduino Uno with hard-wired sensors (temperature, humidity, rain gauge, wind speed, wind direction) and an ethernet shield by adding a MySensors node to each sensor, collecting data into Domoticz.
As part of this I want to keep the ability of my station to upload my weather data to Weather Underground, but this means that I will need to somehow access the 'live' data from my network (or extract it from Domoticz, which I realise isn't anything that can be discussed here).
Does anyone have any ideas of how I could accomplish this? Can I build a 'listening' sensor which can extract and process data 'heard' on the network, or should I be looking at exporting it from the controller side?
Thanks in anticipation!

@TimO To confirm this I just 'rebuilt' my actuator node as the example humidity sensor (swapped a few links on my breadboard) and now the Pin13 LED behaves just like the other sensor node, mostly off with just a tiny flicker on each transmit.
I'm also seeing my ESP8266 gateway crash when the controller requests its version.
I had not seen this thread so I started a new topic here: http://forum.mysensors.org/topic/2493/esp8266-wifi-gateway-crashes-and-reboots-when-controller-connects
If you mean that there is no code in setup{} or loop{} then yes, that is correct.
The new development branch code works differently.
@mfalkvidd These are not extra LEDs added to monitor tx/rx/err (which is what I believe that the MY_WITH_LEDS... compiler directive controls), this is the inbuilt pin13 LED on the arduino board. I do wonder why the library has been written to use this pin as in a battery powered configuration any extra LED current will impact on battery life.
@TimO I agree - the actuator has to listen all the time for incoming messages, whereas the sensor can (and does) sleep for most of the time.
Aaargh! I just downloaded the latest release and now when I try to compile I get this. (In the meantime my Arduino IDE has updated the ESP8266 board definitions). I tried to go back to the previous ESP8266 config but that fails with lots more errors than this!

I have a small system working OK with 2 nodes and a USB gateway to Domoticz.
I just built an ESP8266 WiFi gateway (using the development branch code and libs).
It all compiled and loads OK, but when I try to link it to my Domoticz controller the 8266 crashes.
Here is the output from the serial port of the ESP8266... Prior to the controller connecting I can see the outputs from my temperature/humidity/pressure sensor being received OK

I've built 2 sensors so far, one a relay actuator using an arduino pro mini and the other with temperature and humidity sensor using an Arduino Nano. On the nano the Pin13 LED just flickers occasionally (I guess when the radio transmits) but on the Pro Mini the LED is permanently on, with just an odd visible flicker occasionally.
Both nodes work fine, so I'm intrigued as to why the LEDs should behave differently?
