# Indevolt API

Python client library for communicating with Indevolt devices (home battery systems).

## Features

- Async/await support using aiohttp
- Fully typed with type hints
- Simple and intuitive API
- Comprehensive error handling

## Installation

```bash
pip install indevolt-api
```

## Quick Start

```python
import asyncio
import aiohttp
from indevolt_api import (
    IndevoltAPI,
    IndevoltConfig,
    IndevoltEnergyMode,
    IndevoltSystem,
    SET_REALTIME_ACTION,
    IndevoltRealtimeAction,
)

async def main():
    async with aiohttp.ClientSession() as session:
        api = IndevoltAPI(host="192.168.1.100", port=8080, session=session)

        # Get device configuration
        config = await api.get_config()
        print(f"Device config: {config}")

        # Fetch data using StrEnum members — response keys are the same strings
        data = await api.fetch_data([IndevoltConfig.READ_ENERGY_MODE, IndevoltSystem.INPUT_POWER])
        print(f"Energy mode: {data[IndevoltConfig.READ_ENERGY_MODE]}")
        print(f"Input power: {data[IndevoltSystem.INPUT_POWER]}")

        # Write a single value
        await api.set_data(IndevoltConfig.WRITE_DISCHARGE_LIMIT, 50)

        # Write a real-time charge command
        await api.set_data(SET_REALTIME_ACTION, [IndevoltRealtimeAction.CHARGE, 700, 80])

asyncio.run(main())
```

## Device Discovery

The library supports automatic discovery of Indevolt devices on your local network using UDP broadcast.

### Quick Discovery Example

```python
import asyncio
import aiohttp
from indevolt_api import async_discover, IndevoltAPI

async def main():
    # Discover devices on the network (overrides default 3-second timeout)
    devices = await async_discover(timeout=3.0)

    if not devices:
        print("No devices found")
        return

    print(f"Found {len(devices)} device(s):")
    for device in devices:
        print(f"  - {device.host}:{device.port} (name: {device.name})")

    # Connect to the first discovered device
    async with aiohttp.ClientSession() as session:
        api = IndevoltAPI.from_discovered_device(devices[0], session)
        config = await api.get_config()
        print(f"Device config: {config}")

asyncio.run(main())
```

### Discovery Details

The discovery mechanism:

1. Sends AT command `AT+IGDEVICEIP` via UDP broadcast to `255.255.255.255:8099`
2. Indevolt devices on the same network respond to local port `10000` with their IP
3. Returns a list of `DiscoveredDevice` objects with device information

**Note:** Ensure your device and computer are on the same local network and that UDP port 10000 is available.

## API Reference

### IndevoltAPI

#### `__init__(host: str, port: int, session: aiohttp.ClientSession, timeout: float = 10.0)`

- `session` (aiohttp.ClientSession): An aiohttp client session
- `timeout` (float): Request timeout in seconds (default: 10.0)

**Example:**

```python
# Default 10-second timeout (recommended for local devices)
api = IndevoltAPI(host="192.168.1.100", port=8080, session=session)

# Custom timeout
api = IndevoltAPI(host="192.168.1.100", port=8080, session=session, timeout=15.0)

Fetch data from the device.

**Parameters:**

- `t`: A `StrEnum` member, a raw string key, or a list of either

**Returns:**

- Dictionary whose keys are strings matching the requested cJson points. `StrEnum` members can be used directly to index the result.

```

#### `check_discharge_limits(power: int, target_soc: int, generation: int) -> None`

print(f"Device at {device.host}:{device.port}")
if device.name:
    print(f"Name: {device.name}")
```

## Exception Handling

The library provides custom exceptions for API errors and limit violations.

### `APIException`

Raised when there's a client error during API communication (network errors, HTTP errors).

### `TimeOutException`

Raised when an API request times out (default timeout: 10 seconds).

### `PowerExceedsMaxError`

Raised by `check_charge_limits()` or `check_discharge_limits()` when the requested power exceeds the device maximum.

**Attributes:** `power`, `max_power`, `generation`

### `SocBelowMinimumError`

Raised by `check_charge_limits()` or `check_discharge_limits()` when the target SOC is below the hard minimum of 5%.

**Attributes:** `target_soc`, `minimum_soc`

**Example:**

```python
from indevolt_api import IndevoltAPI, APIException, TimeOutException

try:
    data = await api.fetch_data("7101")
except TimeOutException:
    print("Request timed out")
except APIException as e:
    print(f"API error: {e}")
```

**Note:** You can adjust the timeout when creating the API client:

```python
# Increase timeout if needed (e.g., for slower networks)
api = IndevoltAPI(host="192.168.1.100", port=8080, session=session, timeout=10.0)
```

## Constants and Enums

All register keys and action values are available as typed `StrEnum` classes, importable directly from `indevolt_api`. Because `StrEnum` members are strings, they can be passed directly to `fetch_data()` and `set_data()`, and used to index the response dictionary — no manual conversion needed.

### `IndevoltConfig`

Register keys for configurable device settings (read and write).

```python
from indevolt_api import IndevoltConfig

# Write registers
IndevoltConfig.WRITE_ENERGY_MODE      # "47005"
IndevoltConfig.WRITE_DISCHARGE_LIMIT  # "1142"
# ... and more

# Read registers
IndevoltConfig.READ_ENERGY_MODE       # "7101"
IndevoltConfig.READ_DISCHARGE_LIMIT   # "6105"
# ... and more
```

### `IndevoltRealtimeAction`

Action values for real-time control mode, used with `SET_REALTIME_ACTION`.

```python
from indevolt_api import IndevoltRealtimeAction

IndevoltRealtimeAction.STOP       # "0"
IndevoltRealtimeAction.CHARGE     # "1"
IndevoltRealtimeAction.DISCHARGE  # "2"
```

### `IndevoltEnergyMode`

Energy mode values for `IndevoltConfig.WRITE_ENERGY_MODE`.

```python
from indevolt_api import IndevoltEnergyMode

IndevoltEnergyMode.OUTDOOR_PORTABLE
IndevoltEnergyMode.SELF_CONSUMED_PRIORITIZED
IndevoltEnergyMode.REAL_TIME_CONTROL
IndevoltEnergyMode.CHARGE_DISCHARGE_SCHEDULE
```

### `IndevoltBattery`, `IndevoltSystem`, `IndevoltGrid`, `IndevoltSolar`

Register key enums for reading battery, system-level, grid, and solar data points.

```python
from indevolt_api import IndevoltBattery, IndevoltSystem, IndevoltGrid, IndevoltSolar

data = await api.fetch_data([
    IndevoltBattery.SOC,
    IndevoltBattery.POWER,
    IndevoltSystem.OUTPUT_POWER,
    IndevoltGrid.METER_POWER_GEN2,
    IndevoltSolar.DC_INPUT_POWER_1,
])
```

### `SET_REALTIME_ACTION`

The register key used to send real-time charge/discharge commands to the device.

```python
from indevolt_api import SET_REALTIME_ACTION

await api.set_data(SET_REALTIME_ACTION, [IndevoltRealtimeAction.CHARGE, 700, 80])
```

### `DEVICE_LIMITS`

Dictionary of per-generation device limits used by `check_charge_limits()` and `check_discharge_limits()`.

```python
from indevolt_api import DEVICE_LIMITS

print(DEVICE_LIMITS[1])  # {'max_discharge_power': 800, 'max_charge_power': 1200, 'minimum_soc': 5}
print(DEVICE_LIMITS[2])  # {'max_discharge_power': 2400, 'max_charge_power': 2400, 'minimum_soc': 5}
```
