Robomow-BLE 1.2.0

Robomow BLE protocol library

Robomow-BLE

Robomow-BLE is a standalone Python library for talking to Robomow mowers over Bluetooth Low Energy (BLE).

It provides a reusable BLE protocol layer for Robomow mowers and can be used directly in Python applications.

Currently it only supports RT models. Support for other models may be added in the future if there is demand and access to devices for testing.

API Overview

Please refer to the API documentation for details.

How to use

Install

Install from PyPI:

python -m pip install Robomow-BLE

Create a device client

Create a RobomowDevice with:

• mainboard_serial: mower mainboard serial used during authentication.
• update_callback (optional): called for each update as RobomowUpdate(key, value).

from robomow_ble_lib import RobomowDevice

mower = RobomowDevice(
    mainboard_serial="12345678901234",
)

How to find mainboard_serial:

1. Log in to myrobomow.robomow.com.
2. Open your browser's Developer Tools (F12).
3. Go to the Network tab.
4. Reload the page.
5. Look for a request ending in /api/customer/products.
6. Click the request and open the Response tab.
7. In the JSON response, find the field named MainboardSerial. This value is the actual mainboard serial number.

Connect and authenticate

Discover a BLE device with Bleak, then connect:

from bleak import BleakScanner

ble_device = await BleakScanner.find_device_by_address(address, timeout=15.0)
if ble_device is None:
    raise RuntimeError("Mower not found")

await mower.async_connect(ble_device)

Receive updates

Pass a callback to receive state changes:

from robomow_ble_lib import RobomowUpdate, EntityKey


def on_update(update: RobomowUpdate) -> None:
    if update.key == EntityKey.BATTERY_LEVEL:
        print(f"Battery: {update.value}%")
    else:
        print(f"{update.key}: {update.value}")

Send commands

Common control methods:

• await mower.async_start_mowing(duration_minutes=30)
• await mower.async_start_mowing_edge()
• await mower.async_stop_mowing()
• await mower.async_return_to_home()

Common settings methods:

• await mower.async_enable_schedule() / await mower.async_disable_schedule()
• await mower.async_set_schedule(schedule)
• await mower.async_enable_anti_theft() / await mower.async_disable_anti_theft()
• await mower.async_enable_child_lock() / await mower.async_disable_child_lock()
• await mower.async_set_wire_signal_type(wire_signal_type)

Read state

Example state properties:

• Identity/version: family, model, mainboard_version, software_version
• Live values: operating_state, message, battery_level, rssi
• Status: schedule_enabled, next_departure, expected_duration

Disconnect cleanly

Always disconnect in a finally block:

try:
    ...
finally:
    await mower.async_disconnect()

Minimal example

import asyncio

from bleak import BleakScanner
from robomow_ble_lib import RobomowDevice, RobomowUpdate, EntityKey


def on_update(update: RobomowUpdate) -> None:
    if update.key == EntityKey.BATTERY_LEVEL:
        print(f"Battery: {update.value}%")
    else:
        print(f"{update.key}: {update.value}")


async def main() -> None:
    # Replace these with your mower details
    address = "AA:BB:CC:DD:EE:FF"
    mainboard_serial = "12345678901234"

    ble_device = await BleakScanner.find_device_by_address(address, timeout=15.0)
    if ble_device is None:
        raise RuntimeError("Mower not found")

    mower = RobomowDevice(
        mainboard_serial=mainboard_serial,
        update_callback=on_update,
    )

    await mower.async_connect(ble_device)
    try:
        await mower.async_start_mowing(duration_minutes=30)
        await asyncio.sleep(5)
        print("State:", mower.operating_state)
    finally:
        await mower.async_disconnect()


if __name__ == "__main__":
    asyncio.run(main())
