Well designed and easy to install. However there are some interference although they were scheduled on different channels modules (I have purchased 17 with remote controls and 3 channels 1 channel to control awnings and shutters). Being an electronics engineer, I allowed myself to contact the service of Chacon in Belgium. The technician informed me very kindly advised me we reset by stopping the BOX WIFI which could, according to him, the cause of these dysfunctions. I'm going to use soon and give the results of my tests. It would be nice that it works because I planned to buy a central control for all remotely via the Internet.
