Add-ons

WMS Weather Station

Sensors created:

• Wind Speed (m/s)
• Illuminance (lx)
• Battery (%)
• Dusk Level

Installation

1. In Home Assistant, go to Settings → Add-ons → Add-on Store
2. Click ⋮ (menu) → Repositories
3. Add this repository URL
4. Find "WMS Weather Station" and click Install
5. Configure and start

Configuration

Option	Description	Default
webcontrol_host	IP address of WebControl Pro	192.168.1.100
webcontrol_eui	Weather Station EUI — leave blank to auto-discover	(auto)
mqtt_server	MQTT broker URL	mqtt://core-mosquitto:1883
mqtt_user	MQTT username (optional)
mqtt_password	MQTT password (optional)
polling_interval	Polling interval in seconds	30

Zero-config discovery

If webcontrol_eui is left blank (the default), the add-on automatically:

1. Fetches the encryption key from the WebControl Pro's built-in JavaScript
2. Reads the WebControl Pro serial number from its /info endpoint
3. Queries the device registry to find connected weather station EUIs

Only webcontrol_host needs to be set.
