Upload data from Home Assistant to the CWOP.

blueprint:
  name: 'CWOP Upload'
  description: >
    Periodically uploads weather station data from Home Assistant to CWOP
    (Citizen Weather Observer Program) via APRS-IS, whenever any of the
    configured trigger entities change state.

    Setup:
      Add the following shell_command to configuration.yaml. This pipes the
      generated APRS packet to `nc`, which opens a TCP connection to APRS-IS,
      sends the login + weather packet, and closes.

        shell_command:
          cwop_upload: >-
            printf "%b" "{{ packet }}" | nc -w 10 {{ host }} {{ port }}

    Notes on sensor units:
      - Temperature sensors: °F or °C (auto-converted to °F for APRS).
      - Wind speed / gust sensors: mph or km/h (auto-converted to mph).
      - Rain sensors (hourly/24hr/daily): inches or mm (auto-converted to
        hundredths of an inch, per APRS spec).
      - Pressure sensor: mbar/hPa or any other unit assumed to be inHg
        (auto-converted to tenths of a millibar).
      - Luminosity sensor: W/m² or lux (auto-converted to W/m²; values
        ≥1000 W/m² use the APRS 'l' overflow field per spec).
      - Any sensor left blank is reported as APRS "not available" (dots).
