Auto AC Control · No WiFi Needed

Your AC shuts off when the room is empty.

A motion sensor that learns your air-conditioner's remote and switches it off the moment the room goes still — saving power every night. No WiFi, no app, no hub. It just works.

Why Klisens

A tiny disc that switches your AC off for you

Mount it above the bed facing the air-conditioner. It senses the room and, once everyone is gone, sends the OFF signal automatically.

Senses the whole room

A wide infrared lens catches movement across the room and knows when it has been left empty.

No wiring, no WiFi

Runs entirely on its own. Nothing to plug in, no internet, no app and no account to set up.

Learns any AC remote

Point your remote at it once and it copies the infrared signal from most split AC remotes.

Built for empty-room AC waste

One product, several high-value use cases

Proven in real properties

Used by hotels, resorts, and commercial operators

Klisens is already used in guest rooms and commercial spaces where split AC units are often left running after people leave.

One sensor, real savings

Cool while you sleep. Off when you are gone.

  • Sleep all night — light sleep movement keeps it cooling.
  • Leave and forget — step out and the AC switches itself off later.
  • Lower bills — stop paying to cool an empty room every night.

Step 01

Copy your remote

Hold your AC remote up to the sensor and press once. It learns your air-conditioner signal.

Step 02

Mount facing the AC

Stick it above the bed, up to 2.5 m high, positioned toward the air-conditioner.

Step 03

Set the timer

Choose how long of no movement before it powers the AC off. Bedrooms usually use 30 minutes or more.

Good to know

Frequently asked

Does it need WiFi or an app?

No. It works completely on its own — no WiFi, no app, no Alexa and no subscription. Everything happens right on the device.

Which air-conditioners does it work with?

It learns the infrared signal from your existing AC remote, so it works with most air-conditioner brands that use an IR remote.

Where should I mount it?

Above the bed, up to about 2.5 m high, positioned so it can see both you and the air-conditioner across the room.

Will it turn the AC off while I am asleep?

Not if you set it up right. For bedrooms, set the timer to 30 minutes or more so light sleep movement keeps it running.
