OK SOLVED!
I reinstalled the last version of mysensors library and i uploaded again the sketch to arduino node and now i can see my light sensor!

Thank you very much for your help.
Best Regards

If we use pin 22 for CE and pin 24 for CS it is not necessery to declare as you said. But if we want to use other pins we need to declare. I havent try though with other pins.

Make a last try and change the RF POWER parameter when you build the gateway. If it is at high power set it to low power or the opposite. Did you try with other RF24 module?

Is your power supply enough to supply the right current? Also play with the RF POWER when you build the gateway.

Thank you skywatch for your answer. I am talking about RF 433MHz and i have succesfully decode and resend RF commands by connecting RF transmitter and receiver on arduino like this project here: http://www.libremechanics.com/?q=node/31
How can i combine these sketches to make a mysensor node which will be able to read and send the RF commands?

Hi,
I want to make a node to send RF codes to control different devices (alarm system, some switches) which already are controlled from RF remote control. I saw in examples only RF receive decode node. Can anybody help me with RF send?
Thank you.

Hi everybody.
I am running homeassistant on raspberrypi and i have serial gateway on raspberry. I have made 2 nodes with temp hum sensor and they are working fine but i see this warning everytime i reboot homeassistant ''Node 2 is unknown'' the same also for node3. What that means and should i just ignore it?
Also i see this warning ''child_id 1 already exists in children of node 3, cannot add child''

Thank you.

The one chip U4 is high accurancy temperature and humidity sensor. I think its better temperature sensor than the internal temperature sensor of BMP180.

Try persistence: false

Because in 1.5-2 years many things are changing. Did you try my config?

2 years ago were you using version 2.3.1 ?
