Is there a good way to port all sensor nodes from one gateway (serial) to another (ethernet) without loosing the logs?
Is the replace command, which is aviable for the temperature sensors, the right option?

The payload of the nrfs is only a few bytes. There were about 1000 messages sent in with a frequency of about 0,5Hz-1Hz (just guessing from memory)...

But I dont't know if this time is normal...

If that is possible: Ok
My sensors, ok the one in the final version, are in plastic enclosures screwed to the wall. And my switch/RF-Sniffer had problems with the soldering points to the switches on the lid because of the repeatedly opening for flashing.

That was my motivation for using OTA updates

No, it should work with any sketch. It is pretty simple (took me only one afternoon :D ) Here are very good instructions: http://forum.mysensors.org/topic/838/windows-gui-controller-for-mysensors/75 I sucessfully got things working with two nanos. Important points: ser2net works good, but the serial ...

For this kind of debug is the serial monitor the best. Now I am investigating the influence of failed transmissions, the best place for repeaters and systematical errors (e.g. timing). That can only be testet in the whole working system and the domoticz log is not really good for that. So I startes ...

If this works the same as connecting the usb via ser2net, then this will be included in the next version. (Tested here, and working) But it could take a few days because currently domoticz is undergoing some changes that needs to be tested good Are there any disantvantages with using ser2net with a ...

That is right if the voltage is way different from the desired 3.3v.
I had the problem with an 2560 where the serial output of the arduino gave me the message :"check wires"


What does the serial output of the controller tell you?
