Introducing IAMMETER for Apple Watch
Home energy.A glance away.
Want to check your home's electricity use or solar generation without taking out your phone? IAMMETER for Apple Watch puts home power, solar production and grid import or export on your wrist.
For households with an IAMMETER-Cloud monitoring site, the watchOS app makes a quick energy check easier while cooking, working in the garden or moving around the house. Open the watch app for your site readings, or use a watch face complication for a selected metric.

See where your energy is going
Is my home drawing electricity from the grid, or is my solar system exporting? Check on your wrist when you want a quick answer without interrupting what you are doing to find and unlock your phone.
For solar-powered homes
View home consumption alongside solar production and grid power. The grid label changes between Importing and Exporting, so you can see the direction of energy flow without interpreting a negative number.
Before running a flexible load such as a dishwasher, open the watch app and refresh to check the available readings and their sample time. For the full setup behind this view, explore home solar PV monitoring, including generation and grid import/export.
For everyday energy monitoring
Sites without solar get a focused view of home power and energy usage. Where a site provides battery data, the app can also show charging or discharging power and battery state of charge.
Want to see how switching a large load on or off affects total home power? Open the app, refresh and check the sample time. Start with our home energy monitoring system guide to understand the meter and monitoring setup.
The app shows the meter's sample time separately from the app's update time. Available readings depend on your meter, site configuration and cloud data.
Follow today. Keep an eye on the month.
Scroll down from the power overview to see how your energy totals are adding up.
The Today and This month cards show solar yield, energy imported from the grid and energy exported to the grid, in kWh. Cost is displayed when the site supplies billing data and a currency.
Use these summaries for a quick check during the day, then return to IAMMETER on your phone or in your browser when you want to explore detailed charts and reports.
Switch sites without reaching for your phone
Monitor more than one location from the same watch app.
Tap the site name at the top of the dashboard to open your site list. Choose another home or solar installation to view its readings. In Preferences, you can set the default site that opens when the app starts; browsing another site does not change that default.
Put the number you care about on your watch face
IAMMETER complications let you check a selected energy metric alongside the time.
Choose a supported circular, rectangular or inline complication slot. Available metrics include:
- Daily or monthly solar generation
- Daily or monthly grid import and export
- Home, solar or grid power
- Battery state of charge, when available
Set a preferred site and metric under Preferences → Watch face preference. On watchOS 26 and later, you can also configure individual complications in the system editor. Tap a complication to open its site in the app.
Complications refresh in the background when watchOS schedules them. They are not a continuous live feed. A clock indicator marks older retained readings, and unavailable or expired metrics can appear as “—”. Open the app and use Refresh when you need a fresh check.

A few things to know
Compatibility: watchOS 10 or later, paired with your own iPhone. This version is designed for the paired-iPhone experience, rather than Family Setup.
Language: the watch app follows the language selected in the IAMMETER iPhone app after synchronization.
Try the interface: Explore demo lets you browse sample solar and home-energy data without signing in. Demo readings are illustrative and do not populate your real watch face data.
A small screen. A useful view of your energy.
When you just want to know how much electricity your home is using, what your solar panels are producing or whether you are importing from the grid, check your wrist. Keep your phone or browser for the detailed charts and reports.
