ZigBee: Services and Solutions


Maven Systems has vast experience in executing overseas and at-home ZigBee based projects. The extensive work on TI's Z-Stack and our in-depth knowledge of ZigBee's layered architecture (ZCL, ZDO, network layer and MAC layer) has helped our customer to come out with solution in minimum turnaround time.

We enable our customers with quick PoCs (Proof of Concept) based on Raspberry Pi and Beaglebone for home automation and smart metering. The PoCs includes integration of their ZigBee modules with third party ZigBee devices. After a successful PoC, we provide end-to-end solution that includes hardware design and development, support for certification, firmware development, mobile and cloud based solutions.

Solutions

Home automation

ZigBee home automation has components as Ethernet /GPRS gateway server, smart plug based routers and battery powered end devices for sensors.

Maven has worked on Raspberry Pi / Beaglebone based HA Linux gateway server, integrated third party ZigBee certified smart plugs as routers, and designed and developed custom battery powered end devices for sensors.

Application on gateway server was developed to provide the cloud connectivity. Power management was done on sensor side to provide long battery life.

One of the pain points of home automation is to make it work with existing Wi-Fi and Bluetooth network on 2.4GHz frequency band. As part of services, Maven provide testing and verification of frequency agility feature of ZigBee.

Highlights
  • Integration with third party ZigBee certified devices available in market
  • Power management in end devices
  • Ethernet/GPRS based gateway
  • Development of custom cluster to support communication of custom devices
  • Testing and verification of frequency agility

Smart metering

In India, the ZigBee based smart metering solution for residential and industrial areas has following components:

  • ZigBee module which goes into the meter
  • Hand held unit to fetch data from meters
  • Base computer software for bill generation
  • GPRS based gateway for cloud connectivity
  • Cloud platform for remote monitoring of the meters

Maven has end-to-end solution as a single package for meter manufacturers to make their existing meter as smart meters. The RF module is designed in such a way that it fits into existing meters and can communicate over UART. This results in quick turnaround time to market.

With millions of meters to be deployed, there is demand and correspondingly production of thousands of RF modules per week. Maven has a TestJig to test and verify working of these RF modules in in such a less time span.

Highlights
  • End-to-end solution under single roof
  • Integration with utility meters over various interfaces
  • Development of custom cluster as per requirement
  • Base computer software
  • Hand held unit
  • GPRS based gateway
  • Over the air (OTA) firmware upgrade
  • TestJig for production

Street lighting

Street lighting solution needs a RF module to be placed in each lighting pole that can switch on / off and dim the lights as per the user's wish.

Maven has lighting control board with two relay and dimming control, which can be operated from ZigBee based RF module. The GPRS based gateway controls the light over ZigBee.

User can configure schedules for automatic on, off and dim of lights at predefine time on daily basis. The cloud solution gives the remote access to configure the schedule and to manually override the action on lights if required.

The GPRS gateway installed at feeder end has a meter to get the consumption of lights on daily basis. The data collected from the meter is available on cloud for further analysis.

Highlights
  • GPRS based gateway
  • Feeder based gateway to monitor consumption via meter
  • Schedules for automatic on / off / dim
  • Over the air (OTA) firmware upgrade
  • Lighting control board with two relay and dimming control

Case studies

Problem statement

There was a requirement of installing ZigBee enabled electricity meters for wireless meter reading across various locations in India. For most of the conventional meter suppliers, it was a mammoth task to convert their existing meters to the required ones! With the stringent time period, building new meters from scratch with the required functionality was nearly impossible and very expensive. One of the meter manufacturers approached us for a technology solution and was lucky!

How Maven helped

Maven studied the existing meters and developed a ZigBee module that could be integrated with those. In a short span of three months, we transformed the conventional meters to modern wireless meters.
