Pro mini: Did not receive a node id from controller.

[Alberto77]

I successfully implemented a MQTT gateway on a PI and my Nano based sensors are working fine.

As a next step I'm trying to build a Pro mini 3.3 V based sensor.
However the allocation of the node id seems not to work.
The protocol received on the serial interface of the Pro mini looks always like this:

 __  __       ____
|  \/  |_   _/ ___|  ___ _ __  ___  ___  _ __ ___
| |\/| | | | \___ \ / _ \ `_ \/ __|/ _ \| `__/ __|
| |  | | |_| |___| |  __/ | | \__ \  _  | |  \__ \
|_|  |_|\__, |____/ \___|_| |_|___/\___/|_|  |___/
        |___/                      2.3.2

I tried with a new upload of the code, but the results is always the same.
(As mentioned above the other sensors are working fine).

Is there something else I have to consider, while using a Pro mini instead of a Nano?
Thanks in advance for your feedback.

You need to have a controller to hand out node IDs, or use static node IDs.
See https://www.google.com/search?q=TSM%3AID%3AREQ&oq=TSM%3AID%3AREQ

[frits]

... and as no controller supports dynamic ID assignment through MQTT (see https://www.mysensors.org/build/mqtt_gateway), your only option is to set static NODE_IDs.

[Alberto77]

I also tried with the static Node_ID 24, there was no change in the behaviour. Then I tried with 25 and it is working now.

#define MY_RADIO_RF24

#include <MySensors.h>

#define MY_NODE_ID 25
#define OPEN 1
#define CLOSE 0

But the Node_ID seems to be 3 and not 25.

Is there a kind of offeset in the ID?

@Alberto77 set the node id before the include of mysensors

[Alberto77]

Thanks! this made the change. Now the ID is 25 as intended.
But how to explain that a Node_ID of 3 was set, when the #define statement was after the MySensors?

[Alberto77]

@frits: if the MQTT GW do not support the dynamic ID assignement, then what happened to my other sensors (those based on the Nano) They got the Node_IDs from the GW. All the sensors are on the same GW.

The gateway doesn't issue NODE_IDs. The controller does, i.e. OpenHAB or Home Assistant (but not for MQTT connections).
The NODE_ID will survive flashing (as long as you don't erase EEPROM). Have you used another Gateway before, say SerialGateway? This would explain why you have valid NODE_IDs on some nodes.

[Alberto77]

@frits : This is my first GW, but during my early experiments I run it as an Ethernet GW, then I reconfigured to MQTT.
Currently I don't have a controller running but I'm using Node-Red + Influx-DB + Grafana.

So probably during these first experiments, while in Ethernet mode, the Node_IDs were distributed.
I will erase the EEPROMs by the next opportunity and will check the behaviour of my Nano sensors after re-boot.

Thanks for your explanation frits, it helped me to learn more about MySensors.
