Wattson works with Holmes on Mac & PC to help you understand your electricity usage in detail. Wattson saves your data for 28 days, Holmes then saves it forever on your computer.

Wattson Solar Plus:
• tracks and displays both energy produced and energy used in your home.
• glows yellow when you generate more electricity than you use.
• works with all Solar, Wind and Water generation systems and all brands of inverters.
• is simple to install and easy to use.

How it works
The Wattson Solar Plus measures the amount of electricity being used and generated in your home or office at any given time. It shows these values on an easy-to-read display in both numbers and colours.

The Wattson Solar Plus uses sensors that simply clip around the outside of electricity cables to measure power data. The data is then sent wirelessly from the Transmitter to the Display. It works with 230V single phase electricity supplies and uses flexible tariff structures to suit most pricing plans.

The Wattson Solar Plus also works with Holmes, a simple piece of software for MAC or PC which helps you track your energy use and generation graphically. You can also enter your electricity prices. From Holmes your data can be exported to a CSV file, allowing you to analyse it any way you choose.

If you have an old electricity meter, which spins backwards when you are generating more energy that you are using please read this important information about installing the Wattson Solar.

We also sell extra Wattson Sensor Clips if you need them.
