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.

Disables a specific temperature plan so it no longer controls thermostats.
Power Guard
Disable all temperature plans
Disables all temperature plans at once. Useful as a starting point before activating a specific plan.
Power Guard
Plan Number of hours charging hours before Deadline (HH:MM)
Tells Power Guard to pick the N cheapest hours before the deadline and charge only during those hours. All Power Guard power limits still apply. Use this in a flow triggered when the car connects. Example: 3 hours before 07:00.
Power Guard
Pause Charger until Pause until (HH:MM)
Pauses the EV charger until the specified time, even if Power Guard would normally resume it. Useful when you want to delay charging without turning off Smart Price Control.
Power Guard
Charge now (override price control)
Forces EV charging to maximum immediately, ignoring price. Power Guard's power limit still applies — the charger will not exceed your grid limit. The override is automatically cleared when the car disconnects, or you can cancel it manually with 'Cancel charge now'.
Power Guard
Cancel 'Charge now'
Cancels the 'Charge now' override and returns to normal price-controlled charging. Use this if you want to stop forcing max charge before the car disconnects.
Power Guard
Charge now: Charger
Forces the selected EV charger to charge immediately, ignoring price and allowed-hours. Power Guard's power limit still applies. The override is cleared automatically when the car disconnects.
Power Guard
Cancel 'Charge now' for Charger
Cancels the 'Charge now' override for the selected charger and returns it to normal price-controlled charging.
