My idea now: Send WLAN controller on the home network and the signals from the network to the part. Although I have not documented all commands, but this is very easy to accomplish with a little knowledge of the matter.
After spending a little time with the finding of data transferred between phone set and the controller, they are now also runs reliably and I am completely satisfied!
Connecting to existing or new-to-install LED strips is not a problem. The WPS button is another plus for convenience.
The only negative is that the Android app sometimes does not work properly with me and you have to restart it. However, since that could be due to my phone, my network or the like and by self-made control everything works perfectly, I do not see this as a problem of the controller.
From me, saying a strong buy recommendation for all people who want to therefore control one or several LED strips via WLAN and also across rooms and / or want to automate the control via Home Server.
