pymoebot 0.4.0

A Python library intended to monitor and control MoeBot robotic lawn mowers.

pymoebot

A Python library intended to monitor (and control?) the MoeBot robotic lawn mowers.

• MoeBot are controllable over WiFi via the Tuya protocol, using the Tuya apps on your Apple/Android device.
• Tested using an S5 model of MoeBot (which is identical to an S10 (and S20??) apart from battery size).
• A number of other Robot Mowers appear to be physically identical, though it is unconfirmed if they work (or even support WiFi control):
  • JIUDU DM2
  • AYI DRM3 600i
  • Hyundai HYRM1000
  • Gtech RLM50
  • Sømløs G1/G1s
  • iHunt RoboMower APP 2500m2 PRO
  • Parkside PMRDA 20-Li A1
  • Robokos RM600i
• There are some slightly different Robot's that are closely related to the MoeBot, but slightly different, such as:
  • NAC Smart BA-2571
• This library provides a MoeBot facade to the tinytuya library.
• The ultimate intent is to have a library that can then be used within Home-Assistant

Goals

• Monitor the MoeBot
• Control the MoeBot
• Integrate into Home-Assistant stand-alone - see moebot-hass-integration.

History

It was originally intended to utilise the official tuya-iot-python-sdk library but that provided minimal support for the MoeBot. Instead, this library now uses local communication with the MoeBot via the tinytuya library. This does require a little bit of pre-work to identify the LOCAL_KEY for the device so that we can communicate with it.

Regardless of chosen library we are required to have configured a Tuya Cloud project, follow these instructions

Using pymoebot

NOTE: The MoeBot needs to have been activated by adding it to the Tuya/SmartLife app first.

In it's most simplistic use, get an instance of MoeBot, poll for data and then show its attributes.

from pymoebot import MoeBot

moebot = MoeBot('DEVICE_ID', 'IP', 'LOCAL_KEY')
moebot.poll()
print("Battery level: %s%" % moebot.battery)

Alternatively, register as a listener and then start the listening thread on your MoeBot.

from pymoebot import MoeBot

moebot = MoeBot('DEVICE_ID', 'IP', 'LOCAL_KEY')
moebot.add_listener(lambda d: print("Got data: %s", d))
moebot.listen()

# Do some other stuff

moebot.unlisten()

See the examples for further examples of usage.

Communicating with the MoeBot

tinytuya have done all the hard work of communicating with the MoeBot. It is worth sharing my understanding of the specifics about the MoeBot though, since I have made some assumptions and peer-review may be able to identify issues.

The MoeBot (like all other Tuya devices) communicates by way of Tuya Data Points (DPS). Some of these are declared when the mower is queried. Others are provided unsolicited.

import tinytuya

d = tinytuya.Device('DEVICEID', 'DEVICEIP', 'DEVICEKEY')
d.set_version(3.3)
print(d.status())

Will result in:

{'dps': {'6': 100, '101': 'STANDBY', '102': 0, '103': 'MOWER_LEAN', '104': True, '105': 3, '106': 1111, '114': 'AutoMode'}}

Tuya Data Points

State Model

Main States

The following are the declared states of the MoeBot seen so far. They are signified by a '101' DPS.

• CHARGING
• EMERGENCY - the emergency stop button has been pressed (or the device has been tipped/picked up).
• LOCKED - the device is locked and the PIN is required to do anything.
• PAUSED - the mowing session has been paused.
• MOWING
• CHARGING_WITH_TASK_SUSPEND - currently charging but will go back out to mow.
• STANDBY - the mower is not mowing and is charged. May or may not be docked.
• PARK - on the way back to the charging dock.
• FIXED_MOWING - working in a spiral pattern.

EMERGENCY States

The following appear to be sub-states for when the mower is in EMERGENCY state. They are signified by a '103' DPS.

• MOWER_LEAN
• MOWER_EMERGENCY
• MOWER_UI_LOCKED
• PLACE_INSIDE_STATION
• BATTERY_NOT_ENOUGH

Internals

A Facebook user has opened the main case of the MoeBot and taken photos. Refer to the images captured in the 'internals' folder.
