child_id 0 already exists in children of node after loading other sketch



  • Hello, I am having an issue with a sensor with a BMP180 sensor. I can't get the sensor to properly register it seems.
    A fews months ago I tested the same arduino with bmp180 with a modified PressurSensor sketch from the MySensorsArduinoExamples git repo.
    Now I wanted to load the normal PressureSensor sketch with also has a weather prediction included.

    I loaded the PressureSensor sketch on the arduino and it starts but in the HomeAssistant logs i get a message like this :

    Sep 09 15:59:05 keo hass[18926]: WARNING:mysensors:child_id 1 already exists in children of node 6, cannot add child

    So I stopped HA and deleted the whole '6' device from the persistence/mysensors.json
    Started HA and switched on the sensor, same message.
    I record all the readings in a mysql database so I thought maybe that could be the problmen so I deleted the old recordings of the '6_*' entity_id from the states table, stopped HA, removed the '6_' entries from persistence file and switched on the arduino.. Same message again.
    So it appears HA or the gateway arduino already finds the devices somewhere and therefore can't add the new ones. But I fail to see why that is.

    Here is the output of the serial terminal from when I load the sketch on the sensor.

    Is there anything I am missing here ?
    Any pointers are appreciated :)
