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.
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
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.
Setup
Up and running in 90 seconds
No electrician. No drilling. No tools you do not already own.
Copy your remote
Hold your AC remote up to the sensor and press once. It learns your air-conditioner signal.
Mount facing the AC
Stick it above the bed, up to 2.5 m high, positioned toward the air-conditioner.
Set the timer
Choose how long of no movement before it powers the AC off. Bedrooms usually use 30 minutes or more.

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.
