Unlocking Energy Insights with the HomeWizard P1 Meter

That low hum of appliances left on overnight. The quick burst of gas when you boil water. The invisible tug of energy every time the fridge door swings open. It all adds up but most people have no clue how much, or when, or why. Until they plug in the HomeWizard P1 Meter.

It’s one of those gadgets that seems small, maybe even unnecessary until it starts showing you the raw truth about your energy habits. You start questioning that extra fridge in the garage. You realize your nightly Netflix binges actually cost you. You wonder what else is going on that you don’t see. That’s the pull of the P1 Meter. It brings your invisible energy waste into full, measurable view.

And the best part? You don’t need to be techy. No electrician. No renovations. Just plug it into your smart meter, download the app, and start seeing exactly where your power is going and how to take control of it.

What Is the HomeWizard P1 Meter?

The HomeWizard P1 Meter is a compact smart device that connects to the P1 port of your home’s smart energy meter. It reads real-time data about your electricity and gas usage and transmits that info to the HomeWizard Energy app. From there, you can view everything from hourly power usage to solar surplus, standby drain, and even the cost in euros.

It’s designed for homeowners, renters, and solar panel users who want to track energy consumption without needing any technical setup. At just €24.95, it’s positioned as an affordable entry point into home energy awareness.

How the P1 Meter Actually Works

This little device doesn’t guess. It pulls exact data straight from your smart meter, using the standardized P1 port. Here’s the basic breakdown:

• It plugs into the P1 port (available on most SMR 5.0+ smart meters)
• Uses your home’s 2.4GHz WiFi network to send encrypted data
• Updates electricity usage every second, and gas every 5 minutes
• Sends the data securely to your smartphone via the HomeWizard Energy app

And no, you don’t need to power it, not on modern meters. For older smart meters (pre-SMR5), a USB-C adapter is needed. Once connected, it starts measuring electricity import/export, gas usage, and even solar energy surplus if your system is compatible.

Who Is It For?

If you pay a utility bill, this device is for you. But more specifically, it’s ideal for:

• Homeowners who want visibility into where their energy costs are going
• Solar panel users who want to track usage vs. production
• Energy-conscious renters with compatible meters
• Tech-curious users who love seeing real-time data and graphs

This isn’t a niche tool. It’s for anyone trying to waste less and save more.

Installing the P1 Meter (No Tools Required)

HomeWizard made setup deliberately simple:

1. Plug the P1 Meter into the P1 port of your smart meter.

2. Connect it to your WiFi via the HomeWizard Energy app.

3. Done. That’s it.

If your meter is older and doesn’t power the device through the P1 port, you’ll need a USB-C power adapter (sold separately). The app walks you through everything with clear, step-by-step instructions.

The HomeWizard Energy App

Once connected, the app becomes your dashboard. It shows live usage, lets you enter your own energy rates, and calculates daily, weekly, and monthly costs. It also gives you beautiful graphs comparing usage over time.

Some of the best features:

• Real-time tracking of gas and electricity
• Custom energy tariff input
• Standby consumption insights
• Solar production vs. usage
• Alerts for high usage moments

It’s available on iOS and Android, and it's free.

What Does Energy+ Offer?

For €0.99/month, Energy+ unlocks more:

• Data storage beyond 12 months
• Custom alerts for excess usage
• Automation options using solar surplus
• Compare seasonal or yearly data

It’s not required, but if you’re serious about energy optimization, it’s a very low cost upgrade for deeper insights.

Live Data vs Historical Insight

The P1 Meter gives you more than just daily totals. It lets you zoom into moments. How much does that coffee machine pull? Is your TV using power even when off? The app shows second-by-second electricity updates so you can flip a switch and watch the number change.

Pair that with historical data, and you start noticing trends: winter heating spikes, phantom energy loads, the actual benefit of off-peak hours.

Specifications

Let’s talk specs:

• Connection: 802.11 b/g/n (2.4GHz) WiFi
• Security: WPA2/WPA3, 128-bit AES encryption
• Power: <1W draw, passive on SMR5+ meters
• History: 12 months standard (unlimited with Energy+)

Common Issues (And How to Solve Them)

• WiFi disconnections: Keep the P1 Meter close to your router. Mesh systems help.
• Incompatibility: Use HomeWizard’s checker to verify meter compatibility before buying.
• Slow gas updates: It’s normal. Gas usage only updates every 5 minutes.
• Older meters need power: Get the USB-C adapter if your meter is pre-2015.

What About the Rest of the HomeWizard Ecosystem?

Pair the P1 Meter with:

• Wizard Plug In (for measuring device-specific usage)
• Energy Socket (remote control + switching on solar surplus)
• Energy Display (physical dashboard for live readings)
• kWh Meter (solar inverter monitoring)

All devices work together to give a full picture of your home’s energy flow.

Pricing Breakdown

• P1 Meter: €24.95 (one-time)
• USB-C Adapter (if needed): €5 - €10 depending on brand
• Energy+: €0.99/month (optional)

No hub, no hidden subscriptions. You can do a lot with just the base device.

Is It Saving People Money?

Yes, if you actually use the data. Reddit threads are full of users who identified shockingly high standby usage from old TVs, or spotted how much more the oven costs compared to the air fryer. Users say it helps them:

• Spot vampire energy drains
• Time dishwasher/laundry during low tariffs
• Decide when to turn on appliances to use solar surplus

If you’re trying to cut down on bills or make solar smarter, the P1 Meter pays for itself in weeks.

Pros and Cons

Pros:

• Affordable, easy to install
