HomeWizard

Who is HomeWizard?

HomeWizard is a Dutch company based in Noordwijk, on the country’s west coast. It was founded in 2011, originally making home-automation gadgets and app-connected kitchen devices. In early 2021, that changed direction. A colleague reportedly asked whether the company could build something more useful than a smart air fryer. As a result, the team pivoted towards energy almost overnight.

Since that shift, HomeWizard’s mission has stayed fairly consistent. It wants households to see exactly how much electricity, gas and water they use. Alongside that, it shows how much solar power they generate. In other words, visibility comes first, and savings follow once people can act on what they see. That approach has clearly found an audience. The brand reports more than 1,000,000 households using its Energy app. Its average rating sits around 4.7, from over 163,000 reviews.

However, most of that reputation rests on monitoring tools, not batteries. HomeWizard spent years building meters, sockets and displays before it launched any storage product at all. As a result, its battery credentials are still young. Established storage brands have sold home batteries for the best part of a decade. So it is worth judging the Plug-In Battery on its own, newer track record.

HomeWizard’s product range

HomeWizard’s catalogue is still built mainly around monitoring, not storage. Smart plugs, meters and displays make up most of the range. The Plug-In Battery, by contrast, is a recent, single addition rather than a full battery line.

Smart-home and energy-monitoring devices

The core range includes the P1 Meter, a small dongle that reads a Dutch or Belgian smart meter’s P1 port. It then feeds that data into the HomeWizard app. Alongside it sit the Energy Socket, a smart plug with built-in monitoring, plus the Energy Display and the kWh Meter. A Watermeter rounds out the monitoring side, tracking water use. HomeWizard also sells its own inverters and a P1 Splitter for sharing meter data across devices. Home Connect then links everything together. Energy+ is the brand’s optional software tier. It adds features such as price alerts and deeper insights on top of the free app.

The Plug-In Battery arrives

The Plug-In Battery, model HWE-BAT-11, is HomeWizard’s first and so far only home-storage product. It launched in 2024 as a plug-and-play unit, designed to sit beside an existing P1 Meter setup, not replace it. That is because it draws on the same app and meter data. In practice, it fits naturally into a household that already uses HomeWizard’s monitoring tools. For everyone else, it is simply a new name entering a market that established battery brands have served for years.

Inside the plug-in battery

Beyond the headline 2.7 kWh figure, a few details matter more. Look closely at the specs, the warranty and the app that runs everything.

Capacity, output and lifespan

The Plug-In Battery stores 2.688 kWh, usually rounded to 2.7 kWh, using lithium-iron-phosphate (LFP) cells. LFP is a safer, longer-lasting chemistry than older lithium-ion types. HomeWizard rates the unit for about 6,000 cycles down to 70% capacity. That works out at roughly 15 years of typical use. Rated output sits at 800 W, with a maximum apparent output just under 900 VA. That is modest next to some rivals. However, stacking two, three or four units raises combined output to around 1,600, 2,400 or 3,200 W. Round-trip efficiency measured in independent tests came out at about 75%, in line with HomeWizard’s own 70 to 80% estimate. The unit weighs around 25 kg and measures roughly 40 by 20 by 30 cm. That makes it light enough for one person to install. It must, however, stay indoors, in a dry spot.

Warranty and the swap service

HomeWizard backs the Plug-In Battery with a two-year manufacturer’s warranty. Within that period, a faulty unit is collected and replaced free of charge. After that, a separate Swap Service covers years three to seven, or up to about 4,000 cycles. The fee for this was around €329 at the time of writing. That two-tier structure is shorter than the ten-year warranties common among established battery brands. As a result, it is worth weighing against rivals before buying. This matters especially for anyone planning to keep the unit well past year two.

Smart charging and app control

Everything runs through the HomeWizard Energy app, which the brand designs to be simple enough for first-time users. A 2026 update added predictive charging. It uses weather forecasts and expected household use to decide when to charge from solar or the grid. On a dynamic energy tariff, the same feature can time grid charging to cheaper hours automatically. None of this needs a paid subscription, since HomeWizard rolled the feature out to every existing owner for free.

Strengths and limitations

Reviewers consistently praise how easy the Plug-In Battery is to set up. Most people can install it alone in around ten minutes. It plugs straight into a normal socket, with no electrician required for a single unit. Once running, it needs little attention, and the app’s predictive charging adds genuine intelligence without extra cost.

That said, the limitations are just as consistent across independent tests. The 800 W output is low next to rivals offering 2,000 W or more from one unit. As a result, heavy appliances still draw power from the grid. Capacity can run out overnight in homes with higher evening use. In addition, the battery works indoors only, unlike some outdoor-rated competitors. Crucially, it has no backup socket, so it cannot power anything during a grid outage. At roughly €1,395 at launch, reviewers also flagged it as pricier per kWh than several alternatives.

How HomeWizard compares

Against brands such as Anker SOLIX, Zendure and Bluetti, HomeWizard is the newer name in plug-in storage. Those rivals have longer track records in batteries specifically, often with higher single-unit output and outdoor-rated housings. Some also offer a built-in backup outlet for outages. HomeWizard’s edge lies elsewhere, in the simplicity of its app and its head start in energy monitoring.

Availability is another gap worth flagging for UK readers. The Plug-In Battery is sold mainly through HomeWizard’s own webshop, with the Netherlands and Belgium as its core markets. There is no dedicated UK store yet. It also depends on a P1 meter port, a Dutch and Belgian smart-meter standard. UK meters do not use this in the same way. So UK compatibility needs separate checking before anyone buys.

In short, HomeWizard suits households that already trust its monitoring ecosystem and want a low-effort way to try plug-in storage. UK buyers often want maximum power, outdoor flexibility or blackout backup. For them, an established plug-in rival is likely to be the safer first choice today.
