Power Guard
Protect your home from power spikes — controls EV chargers, heaters and more to keep you within your grid limit and reduce your capacity tariff.
Warning! This app might not work properly.
This app version is currently being tested, and has not yet been reviewed. It might not work as expected.
Be extra careful when installing this app.
Power Guard monitors your household power consumption in real-time using a HAN electricity meter and automatically controls devices when you approach your grid limit. It prevents costly peak penalties and tripped breakers by intelligently managing EV chargers, thermostats and other appliances.
Supports Easee and Zaptec chargers, Easee Equalizer as a power meter, and all common HAN meters (Frient, Futurehome, Tibber Pulse, Aidon, Kaifa). Works with any thermostat brand.
When power consumption gets too high, Power Guard steps in — reducing charger current, lowering thermostat temperatures or turning off devices in your chosen priority order. Once consumption drops to a safe level, everything is automatically restored. Set it up once and let it protect your home around the clock.

What’s new
Version 0.8.89 — New: Capacity tariff tier (effektledd) shown as a sensor on the Power Guard device — updates automatically when your monthly peak changes. New: EV Battery virtual device — for users without a car app, add an 'EV Battery' device in Homey and link it to your charger to set battery % manually via a slider. Fix: Power limiting alarm ('Effektbegrensning aktiv') no longer toggles on/off every regulation cycle — it now turns on only when the first device is limited and off only when all devices are fully restored.
Power Guard
This app can manage your entire Homey.
Power Guard is not compatible with the selected Homey.
Power Guard will install on Homey shortly.
