# ~~EverShelf Scale Gateway~~ — DEPRECATED
|
||||
|
||||
> ⚠️ **This app is deprecated and no longer maintained.**
|
||||
>
|
||||
> As of **EverShelf Kiosk v1.6.0**, BLE scale support is fully integrated into the kiosk app itself. You no longer need to install or configure this separate gateway app.
|
||||
>
|
||||
> **If you are using the EverShelf Kiosk app** → the scale gateway runs automatically as a background service. Configure your Bluetooth scale in **step 4 of the setup wizard**.
|
||||
>
|
||||
> **If you are NOT using the kiosk app** (standalone Android tablet) → you may still use this APK, but no new releases will be published.

# EverShelf Scale Gateway (legacy)
|
||||
|
||||
> Android gateway app that bridges Bluetooth LE smart scales with EverShelf via WebSocket.
|
||||
|
||||
---
|
||||
|
||||
## How it works
|
||||
|
||||
```
|
||||
Smart Scale ──(BLE)──► Android Gateway App ──(WebSocket/LAN)──► EverShelf Server ──(SSE)──► Browser
|
||||
```
|
||||
|
||||
The app runs a local WebSocket server (port **8765**) on your Android device. The EverShelf server connects to it via a server-side relay (`api/scale_relay.php` SSE + `api/scale_ping.php` WebSocket client), avoiding mixed-content (HTTPS→WS) issues. Weight readings are streamed to the browser in real time.
|
||||
|
||||
> **Kiosk integration (v1.6.0+):** The gateway is now **built into the EverShelf Kiosk app** as a foreground service. This separate app is not needed when using the kiosk.
|
||||
|
||||
---
|
||||
|
||||
## Supported scale protocols
|
||||
|
||||
| Protocol | Service UUID | Notes |
|
||||
|---|---|---|
|
||||
| **Bluetooth SIG Weight Scale** | `0x181D` / char `0x2A9D` | Most compatible; works with most smart scales |
|
||||
| **Bluetooth SIG Body Composition** | `0x181B` / char `0x2A9C` | Reports weight + body fat %, BMI |
|
||||
| **Generic fallback** | Any notifiable characteristic | Auto-heuristic parsing for 100+ models |
|
||||
|
||||
### Verified compatible scales (community list)
|
||||
- Xiaomi Mi Body Composition Scale 2
|
||||
- Renpho Smart Body Fat Scale
|
||||
- INEVIFIT Smart Body Fat Scale
|
||||
- Any OpenScale-compatible scale (see [openScale supported devices](https://github.com/oliexdev/openScale/wiki/Supported-scales))
|
||||
|
||||
> **Your scale (B09MRXVBV6):** If it implements the standard BLE Weight Scale or Body Composition profile (very likely for modern Amazon smart scales), the gateway will connect automatically. If not, check the [openScale wiki](https://github.com/oliexdev/openScale/wiki/Supported-scales) and open an issue.

|
||||
|
||||
## Download
|
||||
|
||||
Download the latest APK directly: **[evershelf-scale-gateway.apk](https://github.com/dadaloop82/EverShelf/releases/latest/download/evershelf-scale-gateway.apk)**
|
||||
|
||||
---
|
||||
|
||||
## Requirements
|
||||
|
||||
- Android **7.0** (API 24) or later
|
||||
- Bluetooth LE (BLE) support
|
||||
- Both the Android device and the device running EverShelf must be on the **same Wi-Fi network**
|
||||
|
||||
---
|
||||
|
||||
## Setup (step by step)
|
||||
|
||||
### 1. Install the APK
|
||||
Download and install the APK from the Releases page. You may need to allow "Install from unknown sources" in Android settings.
|
||||
|
||||
### 2. Launch the app
|
||||
The app starts the WebSocket gateway server immediately. You will see the **gateway URL** (e.g. `ws://192.168.1.100:8765`) at the top.
|
||||
|
||||
### 3. Connect your scale
|
||||
Tap **"Cerca Bilance Bluetooth"** (Find Bluetooth Scales). Make sure your scale is turned on. Tap it in the list to connect.
|
||||
|
||||
### 4. Configure EverShelf
|
||||
In EverShelf → ⚙️ Settings → **⚖️ Bilancia Smart**:
|
||||
1. Enable the toggle
|
||||
2. Paste the gateway URL shown in the Android app
|
||||
3. Tap **"Testa connessione"** — you should see ✅
|
||||
|
||||
### 5. Use it
|
||||
When adding or consuming a product with unit **g** or **ml**, a **"⚖️ Leggi dalla bilancia"** button appears. Tap it, place the product on the scale, and the weight is filled in automatically.
|
||||

||||

|
||||
|
||||
## WebSocket protocol reference
|
||||
|
||||
All messages are JSON. The server sends these to connected clients:
|
||||
|
||||
```json
|
||||
// Scale status update
|
||||
{"type":"status","state":"connected","device":"Mi Scale 2","battery":85}
|
||||
{"type":"status","state":"disconnected"}
|
||||
|
||||
// Weight reading (broadcast continuously while scale is active)
|
||||
{"type":"weight","value":72.50,"unit":"kg","stable":true,"timestamp":1712345678000}
|
||||
|
||||
// Response to ping
|
||||
{"type":"pong"}
|
||||
```
|
||||
|
||||
Clients can send:
|
||||
|
||||
```json
|
||||
{"type":"get_status"} // Request current status
|
||||
{"type":"get_weight"} // Request next stable weight reading
|
||||
{"type":"ping"} // Keep-alive
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Build from source
|
||||
|
||||
### Prerequisites
|
||||
- Android Studio Hedgehog (2023.1) or later
|
||||

|
||||
|
||||

|
||||
```bash
|
||||
# 1. Clone the repo
|
||||

|
||||
|
||||
# 2. Download the Gradle wrapper (if not included)
|
||||
gradle wrapper --gradle-version 8.4
|
||||
|
||||
# 3. Build debug APK
|
||||
./gradlew assembleDebug
