For Homey Pro
Homey app for Homey Pro
PELS watches your total power usage and turns down heaters, water tanks, ventilation, and EV charging before you hit your capacity limit. The moment there is room again, it brings them back in priority order. It plans Smart tasks around deadlines and shifts flexible load into the cheapest hours of the day, automatically, every hour, without you watching the meter. With solar panels or a home battery, PELS sends your surplus to useful load and uses the battery to hold your limit at its place in your priority order, by default before it turns anything down.
Already installed? Open the Homey app and go to More > Apps > PELS > Settings. The Set up PELS card there shows what to do first.
In practice
What PELS does for a home over one day, shown in its own screens and Homey widgets from a demo home.
Cooking, showers and the car all want power at once. PELS holds back the lowest-priority devices for a few minutes and brings each one back as soon as there is room. The Held-back devices widget shows who is waiting, and Let it run now overrides any of them.

Ask for 80 % by 06:30. PELS charges in the cheapest hours that still get there, stays inside your limit while it does, and shows how it went when the task ends.
Smart tasks
Give the water heater a temperature and a deadline. PELS picks the cheapest hours that still reach it, shows the energy needed and the estimated cost, and tracks progress until it is done.
Hot water and heating in cheaper hours
Surplus solar goes to hot water, heating, the car or a home battery instead of the grid. Usage shows what your panels produced and how much of it your home used.

PELS fits any home with a Homey Pro, a whole-home power meter and a few devices that use a lot of power, such as heaters, water heaters, ventilation or an EV charger. Pick the problem closest to yours. Start with the use-case page when one exists, then continue into the setup guide.
A capacity tariff, known in various countries as kapasitetsledd, capaciteitstarief, effektavgift or tehomaksu, charges for your highest hourly or quarter-hour power. If you have one, or just want the house to stay under a set level, start with power limiting. PELS watches whole-home power and turns down lower-priority devices before you cross the limit, on an hourly or a 15-minute average.

If your charger is paired in Homey, PELS calculates the charging current while still protecting the house limit. Some chargers, such as Easee, take that current directly; for others a Flow passes it to the charger app. If the real goal is a battery target by morning, use deadline charging with state of charge.

With a dynamic electricity contract, known in various countries as dynamisch energiecontract, dynamischer Stromtarif or spotpris, a water heater, heat pump, floor heating, panel heater or ventilation unit can run when power is cheapest. Use price shifting, Smart tasks or Flow-booked cheap hours. The hard cap still takes priority.

With solar panels, PELS puts your surplus to work in hot water, heating or the car, even behind an inverter limited to zero export, and the Usage tab shows what your panels produced and what that saved you. A home battery joins your priority list: your sun goes to devices and the battery in your order, and when the house nears its limit the battery discharges on its turn, by default before anything is turned down.

If your home should behave differently when you are home, away or asleep, configure modes and switch them from Homey Flows. Modes can change comfort targets and priorities without rebuilding your automations.

PELS needs whole-home power and, for price features, a price source. Homey Energy can provide both in many setups; Flow data can be used when you already have another meter or price source.

Get started
Install the app, connect your power meter, set a limit, and pick one or two devices PELS should control. That is enough to start learning how it behaves. You can add EV charging, modes, Daily Energy Budget and Smart Tasks later.
Install PELS from the Homey App Store, open its settings under More > Apps > PELS, and follow the Set up PELS card: your power meter first, then the devices PELS manages.
