Melnor Bluetooth

Melnor Bluetooth is a reverse engineered implementation of the Bluetooth protocol for all "smart" bluetooth-enabled watering valves under the Melnor, EcoAquastar, Eden, and other brands.

The library should run on MacOS, Linux, or Windows. It's primarily developed on MacOS and other platforms likely have bugs. PRs and tests are welcome to improve quality across all platforms.

Getting Started

CLI

A simple CLI has been provided for basic debugging purposes. It's not intended for any real use and isn't suitable for running a valve in the real world.

This project uses poetry for dependency management and building. Running this project locally is as simple as the following steps:

1. Clone the repository
2. poetry install
3. poetry run cli.py

The python API has been designed to be as easy to use as possible. A few examples are provided below:

Read battery state

import asyncio

from bleak import BleakScanner  # type: ignore - bleak has bad export types

from melnor_bluetooth.device import Device

ADDRESS = "00:00:00:00:00"  # fill with your device mac address


async def main():

    ble_device = await BleakScanner.find_device_by_address(ADDRESS)
    if ble_device is not None:
        device = Device(ble_device)
        await device.connect()
        await device.fetch_state()

        print(device.battery_level)

        await device.disconnect()


asyncio.run(main())

Turn on a zone

import asyncio

from bleak import BleakScanner  # type: ignore - bleak has bad export types

from melnor_bluetooth.device import Device

address = "00:00:00:00:00"  # fill with your device mac address


async def main():
    ble_device = await BleakScanner.find_device_by_address(ADDRESS)
    if ble_device is not None:
        device = Device(ble_device)
        await device.connect()
        await device.fetch_state()

        device.zone1.is_watering = True

        await device.push_state()
        await device.disconnect()


asyncio.run(main())
