Thinka for KNX allows you control your home with Siri and Alexa.
Thinka allows you to manage your lights, switches, curtains, (Venetian) blinds and climate control. And it reads sensors such as temperature, humidity, CO2, motion, contact and occupancy.
You can use Apple's Home App on your iPhone or iPad to switch on lights, close the curtains or turn up the heat. Or do it all at once with HomeKit scenes. And share with all people in your household.
The Thinka is typically installed on the DIN-rail, connected to KNX via twisted pair, Ethernet and power.
