Here’s what i tried for my yaml:

- platform: mqtt
  state_topic: 'home/OMG_01/LORAtoMQTT' # MQTT topic, check MQTT messages; replace AA... with id (BLE MAC) of your device
  name: "Soil_1"
  unit_of_measurement: '%'
  value_template: '{{ value_json["adc"] }}'
  expire_after: 21600 # 6 hours
#  rssi: -33
#  snr: 9.75

modified my message to get this:

{“id”:“LoRaADC”,“name”:“Soil_1”,“model”:“LSMS092D”,“tempc”:22.35603,“hum”:44.68327,“adc”:880}
