Update Arduino code without becoming a new node in Domoticz?

[popunonkok]

Is there a way to update the Arduino code without the attached sensors becoming new sensors in Domoticz?

My Example is that I now have a fully functional node with 2 switches (Door/Lock). However. I would like to modify the Arduino code so that I can add the function to send Battery status as well.

Is there a way? I guess the same goes for Updating a node if the MySensors Library version changes.

If I am not mistaken, your sensor will keep it's node ID. This means your sensor in Domoticz will stay the same. It only gets a new node ID is you use the ClearEprom.ino sketch if I remember correctly. Hopefully someone can confirm this?

Yes, the node ID is stored in the eprom. However, the eprom overwritten when a new sketch is uploaded. Include a line in the sketch to assign the node ID.

#DEFINE MY_NODE_ID 6

Hmm, in my (anecdotal) experience, the nodes I have worked with do not get a different ID until I use the ClearEprom sketch. Just reflashing a modified sketch does not change it. Or is it the controller (Domoticz) that causes this maybe?

I noticed that using an USBASP with arduino IDE does clear the EEPROM memory.
To keep my nodes ID, I have to dump the EEPROM before updating (via avrdude command line), flash my new program, then write back my EEPROM dump.

If you just program Arduino with standard USB interface, the node ID stays in eeprom
