# GrundfosAlpha Binding

This adds support for reading out the data of Grundfos Alpha Pumps with a [Grundfos Alpha Reader](https://product-selection.grundfos.com/products/alpha-reader)

The reverse engineering of the protocol was taken from [https://github.com/JsBergbau/AlphaDecoder](https://github.com/JsBergbau/AlphaDecoder).

## Supported Things

- `mi401`: The Grundfos MI401 ALPHA Reader

## Discovery

All readers are auto-detected as soon as Bluetooth is configured in openHAB and the MI401 device is powered on.

## Thing Configuration

### `mi401` Thing Configuration

| Name | Type | Description | Default | Required | Advanced |
|---------|------|-----------------------------------------------|---------|----------|----------|
| address | text | Bluetooth address in XX:XX:XX:XX:XX:XX format | N/A | yes | no |

## Channels

| Channel | Type | Read/Write | Description |
|------------------|---------------------------|------------|------------------------------------|
| rssi | Number | R | Received Signal Strength Indicator |
| flow-rate | Number:VolumetricFlowRate | R | The flow rate of the pump |
| pump-head | Number:Length | R | The water head above the pump |
| pump-temperature | Number:Temperature | R | The temperature of the pump |
| battery-level | Number:Dimensionless | R | The battery level of the reader |

## Full Example

grundfos_alpha.things (assuming you have a Bluetooth bridge with the ID `bluetooth:bluegiga:adapter1`:

```
bluetooth:mi401:hci0:sensor1 "Grundfos Alpha Reader 1" (bluetooth:bluegiga:adapter1) [ address="12:34:56:78:9A:BC" ]
```

grundfos_alpha.items:

```
Number RSSI "RSSI [%.1f dBm]" <QualityOfService> { channel="bluetooth:mi401:hci0:sensor1:rssi" }
Number:VolumetricFlowRate Flow_rate "Flowrate [%.1f %unit%]" <flow> { channel="bluetooth:mi401:hci0:sensor1:flow-rate" }
Number:Length Pump_Head "Pump head [%.1f %unit%]" <water> { channel="bluetooth:mi401:hci0:sensor1:pump-head" }
Number:Temperature Pump_Temperature "Temperature [%.1f %unit%]" <temperature> { channel="bluetooth:mi401:hci0:sensor1:pump-temperature" }
Number:Dimensionless Battery_Level "Battery Level [%d %%]" <Battery> { channel="bluetooth:mi401:hci0:sensor1:battery-level" }
```
