MY_NODE_ID AUTO doesn't work, what am I missing?

[ikkeT]

Hi,

I was wondering why couple of my boards didn't register to gateway. They kept looping the three lines that happens if hand shake fails. Then I thought to try fixed ids.

+//#define MY_NODE_ID AUTO
+#define MY_NODE_ID 3

I changed the above, and surprise, both of the boards do work now. Is that auto node id assignment not working in such way? MySensors 2 in question, the devel branch.

Or is this not even supposed to work, and I'm wasting everyone's time?

BR,

hmmm.... this went accidentally to hardware section. I was aiming for troubleshooting. Oh well...

The ID is assigned by the controller, not by the gateway.

@TimO ah, ok, explains as I don't have contoller configured yet. I assume it's then only such controller that speaks MySensors, not anything behind mqtt?

I'm not aware of a controller that is able to hand out IDs via MQTT, although that is possible. So you have to use static IDs with a MQTT gateway.

I think PIDome handles it.
