IoT Smart Beverage Machines

Scan and Drink / Tap and Drink

The No.1 coffee brand by size & revenue in India offer coffee services through their flagship retail outlets, and through machines setup in your office premises. As part of corporate retail strategy, our customer generally setup the vending machines in their customer office premises, supply essentials (coffee & sugar sachets) on daily basis and charge monthly. To offer superior & consistent & customized coffee experience to every consumer on retail outlets, our customer decided to IoTify coffee machines, and digitize their menu & cloudify their billing operations. The main objectives are coffee beans should never run out of stock, customers should always get the same consistent flavor of coffee that they are accustomed to. And customer has chosen Kemsys as their IoT partnet. That’s where Kemsys comes in.

IoT Communication Board

Kemsys team has designed IoT communication board which interacts with Coffee machine controller board & HMI board on one side over UART; and interacts with Microsoft Azure Cloud on another side using RESTAPIs via 2G SIM card connectivity. This board plays vital role in sending Device to Cloud messages & in receiving Cloud to Device commands. We have deployed Azure IoT Hub C-SDK, and used to sync coffee consumption information & daily machine logs with Azure Cloud.

Kemsys team has provided relevant functionality to change the machine menu & Capuccino / Latte preparation settings (configuring coffee beans, water, milk quantities, grinding time etc… for beverage preparation) from remote locations using cloud portals.

HMI DESIGN

Kemsys team has designed touch-screen interface panel to dispense various beverages (Cappuccino, Espresso, Latte, Milk, Tea, and etc…). The HMI solution is designed around STM32 microcontroller.

Kemsys team has ported Android OS on STM32 microcontroller, and HMI application is developed using QT tools – and achieved ultimate performance & tiny footprint.

Key Components:

  • STM-32
  • LCD Display
  • CapSense for Touchscreen
  • QT for HMI application
  • Android OS

Scan & Drink: Making Coffee Machines usher in Post-Covid World

The coffee machine comes with touch panel, using which one can brew & enjoy their favorite cup of drink. Just to enable touchless interactions in post-covid world, Kemsys team has quickly come up with following QR based solution. QR code stickers has been attached to every machine with embedded machine code & single page web URL. On scanning the code using mobile phones, one can navigate to the web-page, where menu will be displayed. Consumers can select & confirm their drink.

Kemsys team has designed and developed the entire Azure based IOT backend – which forwards the drink information as C2D message to specific coffee machine using MQTT protocol. Upon receiving the command, the IoT communication board instructs the machine controller board to brew the requested drink.

Kemsys team is quick and agile enough to design & develop entire solution with in 4 weeks, that to while covid lockdown is going on. This Scan & Drink application is deployed in those corporate office where coffee machines are placed and charged lumpsum per month; and individual coffee cups tracking is not important.

Tap & Drink: Enabling touchless interactions, Tracking coffee consumption

The coffee machine comes with touch panel, using which one can brew & enjoy their favorite cup of drink. Just to enable touchless interactions, in post-covid world, and at the same time to keep track of – who has consumed & how many cups consumed, Kemsys team has quickly come up with following BLE based solution. This solution is deployed specifically for corporate customers.

Every employee to have mobile app. Every coffee machine to have BLE beacons, continuously advertises. The moment, app is opened, smartphone scans & displays nearest coffee machines. Upon selection, the smartphone pairs with relevant coffee machine. From this moment, the command exchange happens over BLE with coffee machine, and displays the menu. Once user selects & confirms the menu item, coffee machine brews same.

Both smartphone & coffee machine – syncs this coffee consumption information with Azure cloud, for monthly billing purpose.

Management of Coffee Machines @ Scale

Kemsys team has IoTified all coffee machines, and connected to Microsoft Azure IoT Hub using C-SDK. Kemsys RDM software (Kemsys IP & Accelerator) played big role in this digital transformation.

Kemsys team has quickly enabled map view of coffee machines, came up with dashboard with vital stats like – how many coffee machines are healthy & connected; and how many are down & need attention. This RDM comes with simple interface to register, configure, and control individual coffee machines. One more interesting feature is, with the help of RDM, Kemsys team has enabled remote firmware upgrade feature, and FOTA (firmware over the air) campaigns, targeting groups of coffee machines tagged with version & location – with latest patches.
