How it works

From the wall socket to a lower bill, in four steps.

Most smart-home devices watch and report. Cerloq One acts on what is actually happening in the room. Here is how.

01 · Your AC, ready in seconds

200+ AC models. Pick yours. Done.

Choose your air conditioner from a library of 200+ models across 39 brands — Daikin, Mitsubishi, LG, Samsung, Panasonic, Gree and more. The five presets Cerloq needs install in seconds, and new models keep arriving without you doing anything.

02 · Not in the library?

Any remote. A few presses.

Point the AC’s own remote at Cerloq and press the buttons you want it to know. Off and cool are enough for the automation; teach all five and you have full control from your phone — so an unusual or older unit works like one from the library.

03 · It knows when the room is empty

The room decides, not the calendar.

Nothing to connect. A radar in the device senses whether anyone is inside, even asleep. It waits ten minutes to be sure the room is empty, eases the AC back, and switches it off ten minutes later. When someone comes back, Cerloq steps aside at once and leaves the AC to them.

04 · Savings you can check

Measured hours, not a marketing estimate.

Every time the AC was running, the room was empty and Cerloq switched it off, the hours go into your savings log with a start and an end. Euro figures follow from your tariff and the AC’s capacity. If in doubt, we count less, never more.

What Cerloq never does.

No microphone. Ever.

There is no microphone in the device, and there never will be. Nothing said in your apartment can be heard, recorded or transmitted.

No camera. Ever.

Presence is sensed by a 24 GHz radar that produces no image of any kind. No video data is collected, transmitted or stored.

No live feed of your guests.

Whether someone is in the room is used by the device to run the AC — it is never streamed to you or to us. You see the AC, the savings and the property’s state, never the person.

Never sold. Never shared.

Every message travels encrypted. Your climate readings and savings are stored in Europe, and nothing is ever sold or shared with advertisers.

See it work before you buy.
