The way Wattson works is really quite simple. When you buy the device , you’ll also get a sensor clip and a transmitter. The sensor clip attaches to either of the mains electricity cables leading from your home’s meter box to your fuse box. It’s easy to do, though if you’re in any doubt, ask the advice of a qualified electrician or contact the Wattson helpdesk.



The sensor clip and transmitter measure the electricity coming into your home, and on the Wattson display, it displays in watts or in cost how much electricity your home is using at any moment.

On the underside are coloured lights which also show how much energy you’re using. When the lights glow blue, you’re using less electricity than normal. When there’s a purple glow, you’re using the average for your home. And when they’re red, you’re using more electricity than usual. Simple!
