# SwitchBot Temperature Dashboard

Dockerised SwitchBot temperature monitor with:

- Flask web dashboard for desktop and mobile.
- Python collector polling the SwitchBot API v1.1.
- MySQL storage.
- Auto-populated device names from the SwitchBot API.
- Configurable collection interval, defaulting to 15 minutes.
- Day-so-far temperature graph with high/low cards.
- Date-range reports with CSV export.

## Quick Start

Create your local environment file:

```sh
cp .env.example .env
```

Edit `.env` and set:

```sh
SWITCHBOT_TOKEN=your-token
SWITCHBOT_SECRET=your-secret
FLASK_SECRET_KEY=a-random-local-secret
```

Start everything:

```sh
docker compose up --build
```

Open:

```text
http://localhost:8000
```

The collector service will create database tables, discover devices, and begin
recording temperature/humidity readings. To change the polling interval, update
`COLLECT_INTERVAL_SECONDS` in `.env`; `900` is 15 minutes.

Compose builds the internal database URL from `MYSQL_USER`, `MYSQL_PASSWORD`,
and `MYSQL_DATABASE`. Set `DATABASE_URL` only if you want to point the app at a
different database.

## Reports

Open `/reports` in the web app to generate a date-range summary. Use the
download button for a CSV export.

## Services

- `db`: MySQL 8.4 with persistent `mysql_data` volume.
- `web`: Flask app served by Gunicorn on port 8000.
- `collector`: SwitchBot polling loop.

## POC Script

The original proof-of-concept script is still available:

This demo signs a SwitchBot API v1.1 request and prints the JSON response.

## Usage

Set your credentials as environment variables:

```sh
export SWITCHBOT_TOKEN="your-token"
export SWITCHBOT_SECRET="your-secret"
```

List devices:

```sh
python3 switchbot_poc.py
```

List devices with an empty-inventory diagnostic:

```sh
python3 switchbot_poc.py --diagnose
```

List scenes:

```sh
python3 switchbot_poc.py --endpoint /scenes
```

Get a device status:

```sh
python3 switchbot_poc.py --endpoint /devices/YOUR_DEVICE_ID/status
```

You can also pass credentials directly:

```sh
python3 switchbot_poc.py --token "your-token" --secret "your-secret"
```

The v1.1 signature is:

```text
Base64(HMAC-SHA256(secret, token + timestamp_ms + nonce))
```

## Empty Device List

If `/devices` returns:

```json
{
  "statusCode": 100,
  "message": "success",
  "body": {
    "deviceList": [],
    "infraredRemoteList": []
  }
}
```

the signed API request is working, but the account behind that token has no
Cloud API-visible devices.

Things to check:

- The token and secret were generated from the same SwitchBot app account that
  owns the devices.
- You are not logged into a different SwitchBot account, Apple/Google login, or
  home/family than the one containing the devices.
- The devices appear in the SwitchBot mobile app while logged into that account.
- Bluetooth-only devices such as Bots, Locks, Curtains, and Meters generally
  need to be reachable through a SwitchBot Hub for cloud/API access.
- If using app version 9 or newer, SwitchBot says the old manual "Cloud Service"
  toggle was removed for some devices; keep the device near a Hub and verify it
  is remotely controllable from the app.
