PWS

This Home Assistant configuration allows you to get the data directly from your own PWS (personal weather station). So this does NOT require that you register your PWS to cloud accounts, like WeatherUnderground (support will finish in the near future!), Ecowitt, WeatherCloud, WOW (takes weeks to get key), etc, or the use of WeeWX (extra software).

This configuration will directly capture the data from your weather station!

Support

By me a 🍺

Supported devices

In general, if the station is supplied with EasyWeather software (version 1.4.x, 1.5.x, 1.6.x), it is likely that the station will work with this HA Configuration!

Prerequisites

Your PWS needs to be connected to your network. This can be done by using WS View app.

WS View Plus (WS View or WS Tool)

If supported by your PWS, connect your PWS with WS View Plus (and also the 'older' WS View or WS Tool) to your router by wifi, so that your PWS can upload weather data to Home Assistant.

1. Install WS View Plus on your mobile device
   • Google Play Store
   • Apple App Store
2. , or WS View
   • Google Play Store
   • Apple App Store
3. , or WS Tool
   • Google Play Store
   • Apple App Store
4. Follow the instructions to connect your PWS to your router
5. Goto to Device List in Menu and choose your PWS
6. Click on Next until you are on on the Customized page
7. Choose Enable
8. For Protocol Type Same As choose Ecowitt
   • With Ecowitt the data will be send with a POST. Wunderground is using a GET, which is not (yet) supported by a HA webhook.
9. For Server IP / Hostname enter your HA Server ip address, eg. 192.168.0.10
10. For Path enter: /api/webhook/pws
11. Port enter a port number 8123
12. Upload Interval, leave it 60 seconds
13. Click on Save

Configuration

Use the latest version of HA!

Use the configuration.yaml to setup the PWS entities.

Use the customize.yaml to get appropriate icons for the entities

trigger:
  - platform: webhook
    webhook_id: pws
action:
  - service: persistent_notification.create
    data_template:
      message: |-
