Good day friends,
I would like to start a project for controlling by phone App of my curtains motors which are presently controlled by KNX controllers and KNX switches in different rooms. Such ready devices exist but the cheapest I found cost above 550 EUR. Furthermore it has not skills for Alexa.
Well, I found in internet many topics how to connect Arduino to KNX network, record the telegrams from switches and then send same telegrams to the controllers for imitation of switches actions. The easiest and cheapest interface from serial to KNX bus is by Siemens KNX buss coupler. That is the easier part for me.
However I have no experience how to control Arduino from Phone App via WiFi or Zigbee. I also have not experience in programming for Android or iOS phones. May somebody help in that?
