homebridge-grizzl-e

A Homebridge plugin for Grizzl-E Connect EV chargers by United Chargers.

Each charger in your Grizzl-E Connect account is exposed as a HomeKit accessory with full charging status visibility and control — all on a single accessory detail page.

HomeKit Accessory

Each charger exposes the following:

Outlet (main control)

| Feature | Description | |---|---| | On / Off | Enable or disable charging | | Outlet In Use | Lit when the car is actively drawing power | | Fault | Warning badge shown when the charger reports an error | | No Response | Shown when the charger is offline |

Car Plugged In

An occupancy sensor that activates whenever a car is physically connected to the charger — regardless of whether charging is active or paused.

Connector Status Sensors

Five individual occupancy sensors, each usable as a HomeKit automation trigger:

| Sensor | Active when... | |---|---| | Preparing | Car is connected and the session is initializing | | Charging | Car is actively drawing power | | Suspended by Charger | The charger (EVSE) has paused the session | | Suspended by Car | The car's battery management system has paused the session | | Finishing | The charging session is winding down |

These map directly to the OCPP standard connector statuses (Preparing, Charging, SuspendedEVSE, SuspendedEV, Finishing).

Requirements

• A Grizzl-E Connect account with at least one charger
• Homebridge v1.6.0 or later
• Node.js v20 or later

Installation

Search for Grizzl-E Homebridge in the Homebridge UI, or install manually:

npm install -g homebridge-grizzl-e

Configuration

Configure via the Homebridge UI, or add to your config.json:

{
  "platform": "GrizzlE",
  "name": "Grizzl-E",
  "email": "[email protected]",
  "password": "your-password",
  "pollInterval": 30
}

| Field | Required | Default | Description | |-------|----------|---------|-------------| | email | ✅ | — | Your Grizzl-E Connect account email | | password | ✅ | — | Your Grizzl-E Connect account password | | pollInterval | ❌ | 30 | How often (in seconds) to poll for status updates (10–300) |

How It Works

The plugin authenticates with the Grizzl-E Connect cloud API using your account credentials. All chargers in your account are automatically discovered. The plugin polls the API on a configurable interval and pushes state changes to HomeKit immediately as they occur.

Chargers that are offline (not connected to the internet) show No Response in HomeKit rather than stale data.

Automations

Because each status is exposed as an individual occupancy sensor, you can build precise HomeKit automations:

Demand response (paired with homebridge-hilo-challenge):

• When Hilo Reduction sensor opens → Turn off charger
• When Hilo Reduction sensor closes → Turn on charger

Scheduled charging:

• When Car Plugged In activates after 11 PM → Turn on charger
• When Car Plugged In activates before 11 PM → Turn off charger (charge overnight instead)

Notifications:

• When Suspended by Charger activates → send notification (unexpected pause)
• When Charging activates → send notification (charging started)
• When Finishing activates → send notification (charging complete)
