Enable dallas sensor module on PIN 23

dallas:

• pin: 23
  update_interval: 60s

The sensor itself

sensor:

• platform: dallas

  flash the config fist without the sensor block

  and pick the dallas address from the log

  address: 0xCD012062C7DCFFFF
  resolution: 12
  id: mysensor
  filters:

  generate the median from 5 values to improve the quality

  the sensor will transmit a value to influxdb each 5 minutes

  • median:
    window_size: 5
    send_every: 5
    send_first_at: 5
    on_value:
    then:

    send the data
