Zoomy A more useful and enjoyable screen for your MG4

Zoomy in your Home Assistant.

Every drive, every charge and every power run from your MG4, in your own Home Assistant. The add-on is free, and your car’s figures stay at home.

What you see

The free Zoomy add-on puts your MG4 into your own Home Assistant: a ZOOMY dashboard in the sidebar, and sensors - last drive, last charge, this month, last month, battery - that your own automations can use. No YAML to write.

Your data stays at home

Once paired, your car sends its figures straight to your Home Assistant over your home Wi-Fi. They do not go through the internet or through Zoomy, and they are kept only on your Home Assistant.

What you need

  1. Home Assistant 2026.9 or newer

    On a computer or box at home, on the same Wi-Fi as your car.

  2. HACS

    The Home Assistant Community Store, which installs add-ons like this one. If you don’t have it yet, its own site explains how to add it.

  3. Zoomy on your MG4

    With the car on your home Wi-Fi.

Install it in three steps

  1. Add Zoomy to HACS

    Tap the button: it opens your own Home Assistant at the Zoomy add-on. Then tap Download.

    Open in HACS

    Or, in HACS: the three dots, Custom repositories, paste github.com/zoomy-zoom/home-assistant-zoomy, choose Integration, then download “Zoomy”.

  2. Restart Home Assistant

    Settings, then the three dots at the top, then Restart Home Assistant.

  3. Add your car

    Tap the button, or go to Settings, Devices & services, Add integration, Zoomy. The ZOOMY dashboard appears in the sidebar by itself.

    Add Zoomy to Home Assistant

Coming in a Zoomy update: pairing your car. Your car will show a 6-digit code and you type it into Home Assistant - nothing else to copy or type. Until that update reaches your car, the add-on is installed and waiting.

An example of what else Home Assistant can do

This is one owner's own Home Assistant set-up: it charges two cars from spare solar power. It is not part of the Zoomy add-on.
