Compatibility, control, charging, and returns
Frequently asked questions
Does Tarken fit my window?
Tarken is designed for inward-opening tilt-and-turn windows. It replaces the existing handle and moves the window mechanism automatically. Review the measurements and clearances before ordering.
If you are unsure, send us photos through the contact page and we will help you check.
Can I install Tarken myself?
Yes. Tarken is designed for self-installation. The Phillips screwdriver you need is included. Most compatible installations take only a few minutes; see the step-by-step user manual.
Can I still open the window manually?
Yes. The physical buttons can close the window, move it to the tilted ventilation position, or release it for full manual turn-opening. Full turn-opening is intended for manual use.
Do I need a hub?
No hub is needed for local Bluetooth control through the Tarken app. Matter over Thread control requires a compatible Matter controller and Thread border router.
Can I use both the Tarken app and my smart home?
Yes. Tarken can be commissioned and controlled through its app and through Matter. When using Matter, it is usually best to create smart-home automations in your chosen ecosystem.
How long does the battery last?
Battery life depends on window resistance, temperature, and how often automations move the window. With normal use, Tarken is designed to run for up to around one year between charges.
Recharge it with USB-C while installed or remove the unit for charging. The included solar panel can reduce or eliminate manual charging when light conditions and usage allow.
Does Tarken detect rain or wind?
Tarken does not contain rain or wind sensors. A compatible smart-home system can use separate sensors or weather data to create rain, wind, or outdoor-temperature automations.
What if Tarken does not fit my window?
Contact us before ordering if you are uncertain; photos and measurements usually make compatibility easy to confirm. Online purchases have a 14-day right of withdrawal after receipt, subject to the refund policy.
How does Tarken move the window?
During normal operation, Tarken locks or unlocks the handle mechanism and moves the window between closed and tilted ventilation positions. Full turn-opening is manual, and percentage-based opening is not supported.
In the Tarken app you can choose full or slight tilt, disable locking, and disable the physical buttons.
