How To Build Your Own BMS Control System

Technology-based solutions have been used to control and monitor equipment in buildings for years. With IoT there’s so much more we can now add to create a more intelligent building management system. Learn how you can create your own BMS control system with Alliot & Wattsense.

BMS control systems provide a range of benefits for Facility Managers and companies alike. Most commonly used to monitor and control a building’s electrical and mechanical equipment such as office equipment, lighting, heating and ventilation. Building Management Systems can be used to:

  • Improve energy efficiencies
  • Make savings
  • Increase staff productivity
  • Improve overall working conditions
  • Reduce Carbon emissions

Up until now, many BMS control systems operate under a technology known as BACnet (Building Automation Control and Network). BACnet is one of the most widely used protocols for automation control – helping you to tie together systems such as security and ventilation to develop a BMS client capable of controlling and monitoring connected entities.

These systems provide a great deal of functionality to existing BMS. But what if we could take this to the next level and create even more intelligent Building Management Systems?

Meet the Wattsense Range


Wattsense’s gateways enable you to connect your existing BMS systems to other protocols to create your own BMS control system. Opening up a whole world of opportunities, with these gateways you can connect any of our LoRaWAN® sensors to your existing BACnet system with minimal disruption. The Wattsense range support the connection of a total of 13 different protocols meaning you can monitor and control devices altogether in one place.

Wattsense Box or Hub – What’s the Difference?

There are two versions of WattSense’s gateway available. Depending on how you wish to control and monitor your intelligent Building Management System will help you to select the best device for you.

The Wattsense Box is centrally managed which enables you to configure and maintain the device over the internet using Wattsense’s cloud platform. This can be particularly useful for Facility Management companies who may manage a portfolio of buildings across multiple locations.

The Wattsense Hub, on the other hand is a stand alone device that does not require an internet connection. The Hub can be managed on-site via USB. This device is better suited to those looking to create a stand alone BMS control system.

What can LoRaWAN sensors bring to my BMS?

The possibilities are endless! Maybe your existing system has highlighted an area where energy costs are higher, but you don’t have enough information to identify why. In this instance, you could use the NKE Smart Plug to monitor and control power to devices which may be left running out of hours.

Or perhaps you want to add a new element to your BMS and optimise waste collections.

Creating an Intelligent Building Management System with IoT

Our wide range of sensors can be applied to an endless variety of applications. In fact, sometimes it can be a little overwhelming deciphering what sensors to apply to your project. To help, we’ve created a case study to demonstrate how you may apply some of our LoRaWAN devices to create an intelligent business management system.

We often find that our customers know what issues they want to solves, but don’t always know how to address these. Our expert team are on hand to assist your with the planning, design and implementation of your IoT projects.

One of the beauties of LoRaWAN is that it can be implemented with minimal cost and disruption. LoRaWAN operates on its own network meaning you don’t have to disrupt any of your existing infrastructure. It also offers a scalable solution to enable you to expand your measurement points as/when your project expands.

Smart Buildings with Alliot

When creating this case study, we began by thinking about three key factors you may wish to address when creating an intelligent building management system, for this purpose we selected:

  • Workplace safety
  • Creating optimal working conditions for staff members
  • Optimising overall efficiencies

These three objectives are often at the forefront of many building/facilities managers agendas. Many want to improve the overall environment of their buildings for staff well being, as well as making savings by improving operational efficiencies. Whatever your objectives, we know that in order to be commercially deployable, your solutions need to offer a positive return on your investment.

The next step we made was to apply the objectives to our chosen application of intelligent BMS’. We put ourselves into the shoes of an office worker (we can just about recall being in the office!) and looked at the journey in and around the building. This lead us to select the following products.

  1. Elsys Desk Sensor: Monitors desk occupancy, temperature and humidity to create optimal working conditions.
  2. Netvox R72615A CO2 Sensor: Improve staff productivity by monitoring CO2 levels.
  3. Kerlink Ifemtocell Evolution Gateway: Transfer data from your sensors to your selected platform.
  4. Kerlink Wanesy Platform: Visualise your recorded data.
  5. Tekelek Waste Bin Sensor: Optimise waste collections.
  6. Kentix SmartXcan: Monitor the body temperatures of employees and visitors to create a COVID-secure workplace.
  7. Netvox R718CK2 Thermocouple Sensor: Remotely monitor your Legionella risk and automatically maintain records.
  8. Robeau Smart Water Meter: Make savings based on water usage and remotely detect leaks.
