Mobile Link Propane (Home Assistant)

A Home Assistant custom integration to surface propane tank level from Generac Mobile Link.

Why cookie-based auth?

Mobile Link can present interactive bot checks (CAPTCHA) during automated login. This integration avoids headless login and instead uses a session cookie you copy from your browser after logging in normally.

Install (HACS)

1. HACS → Integrations → Custom repositories → add this repo (category: Integration)
2. Install Mobile Link Propane
3. Restart Home Assistant
4. Settings → Devices & Services → Add Integration → Mobile Link Propane

Setup: Get your Cookie header

1. Sign in at app.mobilelinkgen.com in your browser
2. Open DevTools → Network
3. Click the request to: /api/v2/Apparatus/list
4. In Request Headers, copy the full Cookie: header value
5. Paste it into the integration setup

If the cookie expires, Home Assistant will prompt you to reauthenticate (paste a fresh cookie).
