Improving Industrial Manufacturing with ANAVI Light Controller

ANAVI Light Controller is an open source WiFi development board for controlling 12V low-cost analog RGB LED strip. Although it has been designed primary for home automation, recently ANAVI Light Controller was integrated in an industrial environment.

Wing.eu is an innovative French start-up company reinventing the shipping. The company specializes in “first mile” logistics and provides services to e-merchants. Their warehouses in Paris, Marseille, Bordeaux and Lyon package and ship e-commerce orders. Wing.eu can be integrated with all leading e-commerce platforms, including the popular open source solutions PrestaShop, Magento and WooCommerce.

Wing’s warehouse using Andon manufacturing system implemented with ANAVI Light Controller and 12V RGB LED strips.

Running around the clock such an innovative logistics business requires excellent organization. To ensure high efficiency of the working process Paul Cancouet, project manager at Wing, implemented the Japanese manufacturing system Andon using ANAVI Light Controller.

Andon is a manufacturing term to alert about a problem in real-time. Pioneered by Toyota after World War II, Andon provides the ability to detect problems affecting manufacturing in real-time and fix them as soon as possible.

Paul and his team at Wing constructed a light indication on each desk at their warehouses, using ANAVI Light Controller, 12V RGB LED strip, appropriate 12V power supply, outdoor wall light, PVC tube and a 3D-printed socket. All Andon light indicators are communicating over the machine-to-machine protocol MQTT. The software on the server is written in JavaScript and Node.js. It spreads the information to Google spreadsheets, Slack channel and a HTML5 web interface that acts as a global monitoring dashboard.

The best part is that Wing.eu shared their server side source code in GitHub. ANAVI Light Controller is also entirely open source as the board has been certified by the Open Source Hardware Association and the default firmware is also available as an Arduino sketch at GitHub. Thanks to open source other factories can easily adopt the same solution and significantly improve the efficiency of their manufacturing process.

Paul Cancouet shared more details as a Crowd Supply field report. His industrial automation has been also covered by cnx-software.com.

ANAVI Light Controller is available at our distributors around the world: Crowd Supply, neven.cz and Pi Supply.

Improved Arduino Sketch for ANAVI Light Controller

How often do you get software or firmware updates for a 2-year-old device? Probably not very often. This is not the case for ANAVI Light Controller! We have a major update of its Arduino sketch for you.

ANAVI Light Controller

ANAVI Light Controller open source hardware WiFi device for controlling a 12V RGB LED strip. It was brought to life through a crowdfunding campaign at Crowd in 2018. Now is January 2020, so this makes it ~2 years old! A lot of things have changed during this time. ANAVI Light Controller has been certified by Open Source Hardware Association (OSHA) and it now on sale at our distributors: Crowd Supply, Pi Supply and neven.cz.

Terminals for connecting 12V RGB LED strip to ANAVI Light Controller

Recently we made a major improvements to the default firmware available as an Arduino sketch at GitHub:

  • Support Home Assistant automatic discovery over MQTT
  • Turn on LED D1 on ANAVI Light Controller if the device is not connected to local WiFi network and needs initial configuration
  • Wait for a few seconds while LED D1 is blinking immediately after turning on ANAVI Light Controller to allow reset by keeping SW1 pressed
  • Append the last 5 characters of the machine ID to the WiFi Access Point (AP) to simplify the identification of the ANAVI Light Controller during the initial setup
  • Support MQTT messages with large payload for reporting back the current state of the RGB LED strips on topic stat/dev-id/color
  • Add DEBUG macros, disabled by default, if enabled additional debug information will be printed in the serial monitor
Changing colors of 12V RGB LED strip through Home Assistant using ANAVI Light Controller

You can either compile and upload the new version through Arduino IDE or just grab the binary from GitHub and flash it on your ANAVI Light Controller.

To learn more how ANAVI Light Controller works out the box with the popular open source platform Home Assistant read our previous article. It reveals the exact steps the setup MQTT Broker in Home Assistant and after that to automatically discover ANAVI Light Controller.

ANAVI Light Controller is suitable for low-cost 12V analog (non-addressable) LED strips. If you need a WiFi development board for controlling digital (addressable) LED strips at 5V or 12V have a look at our other open source product ANAVI Miracle Controller.

Control 12V RGB LED Strip from Home Assistant

Home Assistant is a popular open source platform for home automation. It is written in Python programming language and runs perfectly on Raspberry Pi 3 B/B+ or 4 B. Now, with the latest updates of the Arduino sketch for ANAVI Light Controller it is super easy to control 12V RGB LED strip from Home Assistant through your smartphone, tablet or personal computer.

Have a look at the video and follow the steps below to configure ANAVI Light Controller and change colors of 12V RGB LED strips from Home Assistant.

What Is Required?

The following hardware is required:

How to Install?

  • Install Mosquitto from Hass.io add-on store. Set username and password for login to Mosquitto. Set active Access Control Lists (ACL) for the username and launch Mosquitto (it is recommended to install SSH server prior this step).
  • Add MQTT integration in Home Assistant with enabled discovery (from Configuration > Integrations)
  • Attach the 12V RGB LED strip to ANAVI Light Controller
  • Ensure that ANAVI Light Controller has been flashed the latest version of the default Arduino sketch. If it is not, compile it and after that upload it following this video guide.
  • Turn on ANAVI Light Controller, connect to its WiFi Access Point (AP) and configure it through the captive portal. You must provide your WiFi credentials, MQTT server, username and password. After that ANAVI Light Controller will be automatically discovered by Home Assistant over MQTT.
  • Through Home Assistant change colors or effects of ANAVI Light Controller.

How Does It Work?

ANAVI Light Controller is powered by the ESP8266 microcontroller with WiFi. The default Arduino sketch works with the machine to machine protocol MQTT and implements Home Assistant discovery of MQTT Light component.

As soon as ANAVI Light Controller boots, after it has been configured, it connects to the WiFi network, after that to the MQTT broker and sends retained MQTT message with JSON payload that describes the device. Each ANAVI Light Controller has a unique MD5 ID based on the chip ID of ESP8266. The MQTT integration in Home Assistant discovers ANAVI Light Controller based on the received MQTT message. Thanks to the data in the JSON payload Home Assistant automatically configures the device as MQTT Light.

Home Assistant discovery is a user-friendly way for quickly adding new Internet of Things to the platform. Combined with MQTT and the default firmware for ANAVI Light Controller the process is straight-forward and anyone can do it in a few minutes.
