Using tagdrop to omit subtopic

I need to omit zigbee2mqtt/Home/+/Radiator/set
I thought that this tagdrop would do it but it doesn’t.
Any ideas?

[[inputs.mqtt_consumer]]
  servers = ["tcp://127.0.0.1:1883"]
  topics = [
    "zigbee2mqtt/Home/+/Radiator",
    "zigbee2mqtt/Home/+/Radiator/+",
  ]
  data_format = "json_v2"
  [inputs.mqtt_consumer.tags]
    bucket = "zigbee"
  [inputs.mqtt_consumer.tagdrop]
    position = [ "set" ]
    #topic = [ "*/set" ]
  [[inputs.mqtt_consumer.json_v2]]
    measurement_name = "temperature"
    [[inputs.mqtt_consumer.topic_parsing]]
      topic = "zigbee2mqtt/Home/+/Radiator"
      tags = "_/_/room/_"
    [[inputs.mqtt_consumer.topic_parsing]]
      topic = "zigbee2mqtt/Home/+/Radiator/+"
      tags = "_/_/room/_/position"
    [[inputs.mqtt_consumer.json_v2.field]]
      path = "local_temperature"
      rename = "temperature"
      type = "float"
  [[inputs.mqtt_consumer.json_v2]]
    measurement_name = "valve"
    [[inputs.mqtt_consumer.topic_parsing]]
      topic = "zigbee2mqtt/Home/+/Radiator"
      tags = "_/_/room/_"
    [[inputs.mqtt_consumer.topic_parsing]]
      topic = "zigbee2mqtt/Home/+/Radiator/+"
      tags = "_/_/room/_/position"
    [[inputs.mqtt_consumer.json_v2.field]]
      path = "position"
      rename = "valve"
      type = "float"
  [[inputs.mqtt_consumer.json_v2]]
    measurement_name = "battery"
    [[inputs.mqtt_consumer.topic_parsing]]
      topic = "zigbee2mqtt/Home/+/Radiator"
      tags = "_/_/room/_"
    [[inputs.mqtt_consumer.topic_parsing]]
      topic = "zigbee2mqtt/Home/+/Radiator/+"
      tags = "_/_/room/_/position"
    [[inputs.mqtt_consumer.json_v2.field]]
      path = "battery"
      type = "int"

I’m not sure about the execution order, the tag may be dropped when it still doesn’t exists (it gets parsed later on).

Either try to move that config section to the end of the plugin or use processor.override and put the tagdrop in there
