Whatever your role, we give you the tools to get the most out of your system - we help you put the 'smart' in smart house.

Our Vesta provides direct control of standard Taco, Grundfos, and Honeywell circulators and zone valves. It performs all the functions of a zone controller, differential controller, outdoor reset controller, and setpoint controller in a single device. Unlike the individual stand-alone devices that it replaces, all functions work seamlessly together. Every input, output, and control action is logged to support analysis and fine-tuning.

We believe that it's your system. You should be able to make it work for you. The Vesta controller provides industrial quality reliability with a simple web based interface. It's easy to use. Plug-in sensors and a flexible rule engine give you the tools that you need.

Typical Applications

  • Multi-source heating systems with wood gasification boilers and heat storage.
  • Integration of solar hot water with storage and backup heat sources.
  • Industrial controls.
  • Multi-room heat and air conditioning setback.
  • Complex heat pump systems.

In our experience, very few systems work as designed. Energy is silently wasted due to a variety of unseen problems.

Our goal is to help you get the most out your system - new or old, simple or complex. Our Open Source solution puts you in control: 

  • Monitor temperature, pressure, electrical current, humidity - quickly, easily, and accurately from anywhere. See what's happening at any time.
  • Log your data - every input, every output, every minute. Up to 12 months of data can be logged internally. Data can also be logged to a remote database if desired.
  • Control your environment. Perform direct control of relays, lights, pumps, and fans using simple rules.
  • Analyze system performance. See and understand system behavior.

Control your destiny. The Vesta system includes a powerful web interface and a wide range of sensing and control options with no monthly fees. Read more or contact us for details.
