SunWatt: Solar & Power
Electricity price & PV widgets
Free
Your solar output and today's electricity price on your Home Screen, Lock Screen, Control Center and Apple Watch. Free, no account, no tracking.
Your solar production and the electricity price, always in sight. SunWatt shows both in widgets, on your Lock Screen, in Control Center and on your Apple Watch. Works with Huawei FusionSolar, SolarEdge and PVOutput.
Free. No account, no tracking, no ads.
SOLAR
Connect your solar system and see your current power in kW, today's energy in kWh and today's production curve. SunWatt works with:
• Huawei FusionSolar: paste your kiosk link, or enter the API account your installer creates for you
• SolarEdge: enter your site ID and API key
• PVOutput: enter your system ID and API key. PVOutput works with many inverter brands, such as Fronius, SMA, Enphase, GoodWe and Growatt
• Several solar plants in one app
• Optional live data at home: read a Huawei dongle or a SunSpec inverter on your home network (Modbus TCP, read-only)
The onboarding shows you where to find each one in a couple of minutes.
ELECTRICITY PRICE
• Spain: the regulated PVPC price from Red Eléctrica
• Portugal, France, Germany & Luxembourg, Austria, Belgium, Netherlands and North Italy: day-ahead wholesale prices
• Current price colored by level, so you see at a glance if it is cheap or expensive
• Today's chart and the cheapest upcoming hours
• Tomorrow's prices as soon as they are published
WIDGETS AND CONTROLS
• Small, medium and large Home Screen widgets
• Lock Screen widgets, rectangular and circular
• Two Control Center controls: price and solar
• Choose solar, price or both
• Show the whole day, or the previous 6 hours plus the next 12
• Tap a widget to open the app with fresh data

SIRI AND SHORTCUTS
Ask Siri for the electricity price now, your solar production now, or the cheapest hours. Use them in your own shortcuts and automations, for example to start the dishwasher when power is cheap.
APPLE WATCH
A Watch app and complications show the price and your solar power on your wrist.

PRIVATE BY DESIGN
No account. No tracking. No analytics. No ads. SunWatt only talks to the solar service you choose (FusionSolar, SolarEdge or PVOutput) and to the public price services. Your settings, keys and last data stay on your device. Nothing is sent to the developer.
SunWatt is free. It is not affiliated with Huawei, SolarEdge, PVOutput, Red Eléctrica or Fraunhofer ISE. Day-ahead prices for countries other than Spain come from Energy-Charts (Fraunhofer ISE), licensed CC BY 4.0. Wholesale prices are not the price on your bill.
