Powerdog | AI Energy Terrier

Battery owners across the UK spend hours adjusting settings and checking charts, tariff changes and weather forecasts, all to reduce their energy bills.
For some people, that’s part of the fun. They enjoy experimenting, fine-tuning and managing every detail themselves. PowerDog isn’t built for them.
PowerDog is for anyone who simply wants their battery to work harder to save money without turning energy management into a daily chore.
We take the work off your hands, and every change we make to your battery comes with a clear, plain-English explanation of what we changed and why.
Optimisation, tailored to you. PowerDog's AI studies your usage patterns, and combines this insight with your tariff and predicted solar generation to make decisions on when to charge, hold and export...every day, automatically. No settings to fiddle with, no guesswork.

Works alongside Grid Services Providers: If you're already set up to take part in gridevents, that’s no problem. PowerDog will work seamlessly alongside any independent third party aggregator.
Proof in pounds: We measure what actually matters: money in, money out. See what your battery is doing for your bills in figures you recognise, not confusing energy or power stats.
Know what it's doing, and why PowerDog explains its decisions jargon-free. What it's doing with your battery today and tomorrow, and the reason behind each move. And it gives you an honest look back at yesterday: what worked, what didn't, and why. A system you can trust is one that's honest with you.
Works with your battery, whoever made it. PowerDog is manufacturer-agnostic. Whatever brand of battery and inverter you've got, one simple app takes control. No juggling clunky manufacturer software. We don’t currently support every battery system, but we’re adding new ones all the time.
Built for UK homes. Designed around UK tariffs and the UK grid, for homes with battery storage and solar who want their system to just work and want to see it working.

Meet the new Activity tab. See what Watchdog plans to buy and sell today, then look back at every charge and sale with the time and price. Each day shows how it turned out against the plan, and you can filter by Buying, Selling or Plan. On a dynamic tariff, you’ll also see the day’s half-hourly prices. If a plan can’t run, we’ll let you know, and your battery carries on with its own settings.
