See your Shelly energy data live — a free whole-home dashboard

A quick guide to turning a Shelly energy meter into a live, whole-home energy view with iVamp — free, local, no subscription.

A Shelly EM is a brilliant little device: clamp it around your tails and it measures exactly how much power your home is drawing, second by second. But the numbers on their own only tell you so much. What most people actually want is a live picture of the whole home — where the energy is going, how much your solar is covering, and when electricity is cheapest — without paying a monthly fee or handing your data to a cloud service.

That is exactly what iVamp does. Point it at the Shelly on your network and it turns that raw data into a real-time dashboard you can leave running on a Windows PC, a Mac, a phone or a tablet.

What you can see

• Live power flow. Watch energy move between the grid, your home and your solar in real time — the moment a kettle or heat pump switches on, you see it.
• House supply vs solar. See what you are generating, what you are self-consuming, and what you are importing or exporting.
• Your history. Look back over the day, the week or longer to spot what is really driving your bill.
• Cheapest and peak times. iVamp highlights the cheapest and most expensive windows so you can shift heavy loads to the right time of day.
• Carbon and savings. Track how much you are saving and how green your usage is.

Local by design — no cloud, no subscription

iVamp talks to your Shelly over your local network. Your energy data stays in your home, on your devices — there is no online account to create and nothing leaves your house. It is free to use, with an optional one-off Pro upgrade if you want unlimited devices, your full history and CSV export.
