Configuring MySensor nodes

use this program

Yes, I use the same script. There is no node_id assigned to the node right now.
Can I set the node_id manually? I mean the following steps:
- clear eprom
- boot up the node and the inclusive mode on EasyIoT.
- catch the given node_id (from the logs)
- send and set the new node_id from a serial monitor
Is it working theoretically? (I think no - except if I modify the config files manually)
I will be able to play with it tonight.

Clearing the eeprom did the trick! I now have a dimmer!! Thanks for this nice program.

Thanks for the fast advice it realy helped! The communication looks ok. There is a problem around mysensors library if the node fails to receive the new id.
Here is the log which repeats nearly every second the communication repeats:

write
false

Then try add node again. If node is without id it will not work. Also if node is not added to server it will not work.

Problem solved!
I have tried it with several other nodes. There were working and non-working nodes. The main difference was in the wiring between working and non-working nodes.
I use a 3.3V regulated power input. When the radio is fed from the same power input as the arduino pro mini 3.3V (to raw) - directly from the power supply - the config did not work.
When I feed the radio vcc from the arduino vcc, the node_id is accepted. Funny, but at least it is working.
Thanks for your help!
(the next step will be switching relay nodes based on values of user settings and measured temperatures - thermostat function)

It might be that the pro mini has a capacitor that is smoothing the 3.3V supply to the radio.

You can add a 47uF electrolytic (or tantalum) capacitor across the GND and VCC on the radio module and it might well be OK again.

I did this today to 13 modules and all are nice and stable now.

Also of note is that you seem to be putting 3.3v into the RAW pin. The RAW input is for voltages higher than the modules voltage and therefore needs to go through the on board regulator. If you have 3.3V already it should go directly to the VCC pin (and of course GND).
