Hello,

I would like to control a Systemair K 160 XL Sileo exhaust fan with Homey Pro. It has a 230 V single-phase AC motor rated at 0.45 A / 102 W at 50 Hz.

Does anyone know of a Homey-compatible speed controller suitable for this type of motor?

Since I have not found one, my alternative idea is to use an ELKO One 400HR motor speed controller for the normal low-speed setting and a NodOn SIN-4-1-20 Zigbee relay to bypass the controller and supply full voltage when boost mode is needed—for example, during showering or cooking.

Has anyone tried a similar setup, or can you recommend a better solution?

The installation will, of course, be carried out by a qualified electrician.

Best regards,

Truls
