Energy Meter App
Power flow
Generation, house consumption, battery and grid in one view. You see right away whether the battery is charging and whether you are feeding in or drawing from the grid.
iOS app for SMA PV systems
Your SMA PV system.
Your SMA PV system.
Live. No cloud.
The Energy Meter App shows the live values of your inverters, your battery and your SMA Energy Meter. It reads them directly on your home network, via Modbus or Speedwire. You need no account and no portal. New values arrive every 1 to 5 seconds, depending on the device.
- One-time purchase, no subscription
- iPhone, iPad, Mac
- iOS 15 or later

Does it work with my system?
The app finds supported devices on your network by itself. They must be reachable via LAN or Wi-Fi.

- Sunny Tripower Smart Energy (hybrid)
- Sunny Tripower X
- Sunny Boy Storage 3.7, 3.8, 5.0, 6.0
- Sunny Island Storage 3.0, 4.4, 6.0, 8.0

Not supported
- Sunny Home Manager 1.0The device has no interface that can be used locally.
- Bluetooth connections to invertersNot possible on an iOS device, because iOS does not support Bluetooth SPP. The inverter needs a network connection.
Modbus
On SMA inverters (solar, battery and hybrid inverters), Modbus TCP must be turned on in the device. Where to find the setting depends on the device type, and you often need the installer login for it. The manual explains how. If in doubt, ask your installer. The SMA Energy Meter needs no setup.
Features
From power flow to the cos φ of each phase
The overview shows at a glance where your solar power is going right now. Below it you find the live readings of each device.
History
While the app is open, it records the live values and shows all power flows as a chart. Tap to show or hide single curves, and export the values as CSV.
Single device
A colored ring shows grid import in orange and feed-in in green, along with the split across L1 to L3. Tap the center to convert the power into cost or feed-in earnings per hour, day, month and year.
Measure consumption
Start a measurement with “+” and switch on an appliance in your house. The app shows the energy used in kWh, its cost and the daily average.
Phase plotter
Total power and the three phases as a live curve. This lets you spot load peaks and phase imbalance in your house.
All readings

Frequently asked questions
Before you start
Can I see the values when I am away from home?
Yes, through a VPN into your home network, for example with WireGuard or IPsec. Many routers such as the FRITZ!Box offer this out of the box. Once the VPN is connected, the app works as it does at home.
Automatic discovery does not work over VPN. Add your devices once with their IP address instead.
Does the app show the yield data stored in the inverter?
No. The app only reads the current readings. It does not read the yield and history data that the inverter stores itself.
The app records the history in the chart itself while it is open. When you bring the app back from the background, the chart starts over.
Where does my data go?
Your readings stay in the app. The app only talks to the devices on your network. There is no server, no account and no registration. Data only leaves your device if you send a request yourself via “Support / Contact”.
See the privacy policy for details (in German).
Which devices does the app run on?
On iPhone and iPad with iOS or iPadOS 15 or later, and on the Mac. On the iPad, the app supports Split View. On iPhone and iPad it can also show the power flow on a connected monitor, for example as a fixed display on the wall (see the manual).
You buy the app once and can use it on all your Apple devices.
Your system, live from now on.
Buy once, open it on your home network, done.
