Cannot assign NODE ID

moskovskiy82

Have been running successfully mysensors for quite some time. Now building another sensor and have a nightmare. The manually set NODE_ID gets completly ignored and i don not why just gets itself from out of nowhere. My gateway is a version 2.0 ESP to MQTT

@moskovskiy82 upload the clearEepromConfig sketch (available in Examples->MySensors in the Arduino IDE) and run it once, then re-upload your own sketch.

I think the node is using an old node id stored in eeprom. Clearing the eeprom will get rid of that.

mfalkvidd

on second thought, the problem is that #define MY_NODE_ID 56 is after #include <MySensors.h> in your sketch. It needs to be defined before including MySensors.h

gohan

At least it was getting id 75 😀
