Remarks

  • The springcard/springcore prefix at the beginning of all the topics may be changes using the MQTT Topic prefix register.
  • The {$id} part of the topic is the Device ID taken from the Device ID register. If this register is empty, the Serial Number is taken instead (in hexadecimal, upper case).
