Key Features

Matter over Thread for universal compatibility
The MT25B uses Matter over Thread for direct connection to your smart home, without an additional hub or gateway. Works with Apple HomeKit, Google Home, Samsung SmartThings, Amazon Alexa, and all other Matter-certified platforms. Thread ensures fast response, local control, and reliable connection.

Rechargeable 2600mAh battery
The built-in battery lasts an average of 3 to 6 months with 2 uses per day, depending on the width and weight of your roller blind. Charging is easy via the included 3-meter USB-C cable. An optional solar panel is available (495 x 60 mm) to virtually eliminate the need for charging.

Retrofit solution without renovation
Suitable for roller blind tubes with a diameter of 37-38mm. Slide the motor into the tube, mount the wall brackets, and you're done. No electrician needed, no power outlet required. Ideal for rental properties or situations where there is no power supply near the window.

Three adjustable speeds
The MT25B offers three speed settings: 20, 25, and 30 RPM. Choose a lower speed for quiet operation in bedrooms or a higher speed for wide, heavier blinds. You set the speed using the included remote control (Model ZMT1).

Powerful yet compact
With 1.1 Nm of torque and a maximum load capacity of 4 kg, the MT25B is suitable for most roller blinds, zebra blinds, and Shangri-La shades. Its compact design fits standard 37-38mm tubes without modifications.

How long does the battery last?

The 2600mAh battery lasts an average of 3 to 6 months with 2 uses per day. This depends on the width and weight of your roller blind and the chosen speed. Heavier blinds consume more power. Charging takes several hours via the included USB-C cable.

Will this motor fit my roller blind?

Can I control multiple motors simultaneously?

Yes, via Matter systems, you can group multiple MT25B motors and control them simultaneously. For example: "Hey Siri, open all living room blinds". You can also create scenes where multiple blinds open or close simultaneously.

Yes, the remote control will always work, even after the motor has been paired with your Matter system. This is useful as a backup or for guests who do not have access to your smart home system.

Is the solar panel worth it?

If your window gets a lot of direct sunlight and you never want to charge again, the solar panel is an excellent investment. It provides continuous power without having to remove the motor for charging. Especially useful for hard-to-reach windows or high placements.

Can I adjust the speed?

Yes, the MT25B has three speed settings: 20, 25, and 30 RPM. You set the speed via the remote control. Lower speeds are quieter, higher speeds are faster but make a little more noise.
