I keep getting these error messages in the log file when I start one specific sensor:
child_id 1 already exists in children of node 227, cannot add child
This is an energy meter sensor, using the default sketch from the Mysensors libraries. The sensor works as expected (e.g it shows up in HA and shows values for kWh and W), but everytime it starts I get the above message. Do I need to worry about it?
Here’s the serial log from the sensor:
