This is sensor board i've made 2 days ago :)

I have little success too. I modified some code from other project, and now i can report temperatures(DS18B20), temperatures + humidity(DHT22), motion sensor to Domoticz. Today i will try to handle turning on, and off a switch, and also i am planning to modify relay code to handle my wireless 433MHz wall plugs to work as normal relay. Next time maybe reading status of power meter? But in this case i see a problem - how to read last value of acumulated energy from Domoticz? Now some information about solution. Serial gateway is connected to Raspberry Pi(Domoticz), and there is Node.js script. Script can read, and send messages through serial, and post links to Domoticz by JSON.

What is the best way to disable the power LED? Desolder it?

You can cut the pcb trace leading to this led.

@hek This is everything i can get from google cache - https://www.dropbox.com/sh/lf0cc8fhpijvuoj/AADoKwcwn_Ql26ll_TYrhJdUa .

Thank you for the suggestion. I have changed boards definition by board manager many times, but didn't try just deleting folder. I will try this later today.

@mfalkvidd One more question. Which versions of board manager, MySensors library, and Ardino IDE you suggest? Newest will be best?

@mfalkvidd Deleting that folder(and reinstalling everything once again) helped. After succesfull upload i've looked at serial monitor(without connecting nrf), and there was few messages. Next i've connected radio, and it stopped working. Problem was capacitor on radio. Without capacitor everything is working ok. Thank you again.
