Thanks for your great work.
i have managed to get the worker to connect to the MQTT broker on my home assistant, but i get no data, and sensors are unavailable
i get this on mqtt broker logs
1660905302: New connection from 192.168.1.140:51864 on port 1883.
1660905302: New client connected from 192.168.1.140:51864 as mosqpub|26074-hive02_30 (p1, c1, k60, u'mqtt').

then in the config.yaml for my home assistant i have added
sensor:

• platform: mqtt
  name: hiveos_stats
  state_topic: "hive_mqtt_1"
  value_template: "{{ value_json.params.miner_stats.uptime }}"
  json_attributes_topic: "hive_mqtt_1"
  json_attributes_template: "{{ value_json.params.miner_stats | to_json }}"

• platform: mqtt
  name: hiveos_params
  state_topic: "hive_mqtt_1"
  value_template: "{{ value_json.params.miner_stats.uptime }}"
  json_attributes_topic: "hive_mqtt_1"
  json_attributes_template: "{{ value_json.params | to_json }}"

im a bit confused
should i add a new file somewhere named mqtt_sensors.yaml
and if yes, where should the file be located
