ILIFERobot

All the hard work was done by https://github.com/ksya/ILIFERobot, I merely dabbled with the code at an extremely amateur level to add:

  • MQTT LWT topic for availability
  • add hostname definition
  • separate MQTT topics for state and status to use HA mqtt.vacuum schema:state
  • changed states to satisfy HA requirements
  • new configuration supports send.command service in HA, use "robot:%command%" to invoke
  • add fan topic (still unreliable)
  • add locate command (doesn work in webUI) that beeps the vacuum 10 times when invoked
  • removed UDP, isn't useful
  • add wifi signal quality function
  • calibrated battery reading
  • adjust "S_BUSY" to catch spot and edge clean modes
  • battery calculator uses my battery values
  • add charging boolean since state is now only "docked"
  • add "Reboot ESP" option to webUI and robot:reboot command to restart NodeMCU

Add WiFi capabilities to the ILIFE V5s using a NodeMCU or other ESP module. Beware, this is not an easy project, since there is currently no known way to connect to a debug port or serial output.

I just uploaded this since someone asked. The code is not really polished. Also, I don't have documentation of the hardware mods.

  1. You have to read out the led signals on top for the status
  2. Hijack the IR inputs to emulate the remote and give it signals
  3. Read out the battery voltage using a voltage divider
  4. Detect a voltage on the docking input to check whether it is docked.

This can be connected to:

  • IRPin: 4 (pin D2, pin that is used for sending the IR signals)
  • statusPin1: 14 (pin D5, input pin for robot status (from led signal))
  • statusPin2: 5 (pin D1, input pin for robot status (from led signal))
  • statusPin3: 12 (pin D6, input pin for robot status (from led signal))
  • dockPin: 16 (pin D0, input pin for dock contact)
  • batteryPin: A0

Hardware installation

PCB LED connections for reading robot status

  • t1 = tp47 -> G
  • t2 = tp52 -> nc (probably for the start button)
  • t3 = tp44 -> D5 (led 1)
  • t4 = tp49 -> D1 (led 2)
  • t5 = tp48 -> D6 (led 3)
  • t6 = tp43 -> 3V

PCB IR pin

  • tp19 -> D2 (IR sensor)

The voltage dividers for reading docking and battery status

  • (yellow heat shrink) 10 kOhm between G and D0 --> 100 kOhm between D0 and DOCK+ (red)
  • (blue heat shrink) 10 kOhm between G and A0 --> 100 kOhm between A0 and BAT+ (red)

Insulate

Be sure to protect the NodeMCU from touching the metal plate. Insulate the plate with insulation tape or protect the NodeMCU itself.

Software installation

Change the lines in ILIFERobot.ino to match your WiFi credentials and MQTT server:

const char* WiFi_SSID = "your_ssid"; // LAN
const char* WiFi_PW = "your_password";
const char* mqtt_server = "192.168.5.7";

Compile and upload the software to your NodeMCU

After that, there will be a Web UI available. It will also broadcast status on MQTT topic "ILIFERobot/state". Commands can be send on topic "ILIFERobot/command". For more information, see the Home-Assistant config.

Other findings

I couldn't figure out how to read out digital signals, but if anyone wants to try, you can search the documentation of the CPU. For the ILIFE V5s it is a STM32F030R8.
