So I gained the gateway to control the Weihnachsbeleuchtung and the whole floor lamps. I control everything on ipads and iPhone and I have added myself last year, the APP connector Checker. The trial version for 2 units everything was not a problem but since I wanted to turn 8-10 devices I have updated to the Premium version. Then began mess on. I have the Brennenstuhl RCR3600 and RCS2044 outlets gained are actually ruckzuck logged. But I switch socket A went A + B or C of I turn then went indiscriminately another outlet again. I am bringing not really fast out of the rest but since I have everything first sent back. After 2 months I still had the SteckerCheckerAPP I have a 2nd attempt and what can I say the same problems. After several phone calls with burning chair I have a software update of the gateway performed which also brought no improvement. For any reason I have the outlet then inserted upside down into the socket and lo and behold it works much better and now I turn the outlets to 90% right. From time to spinning something but I can now live. It seems that it does not matter whether the phase is connected is the right or left as the outlet. App I can say that I like it because man himself can make images of the lamps and can integrate them into the APP. The switch from the Internet is or was (the service has been set to yes) was fürn Ar ...! I think the SteckerCheckerAPP you can no longer buy new and I had been looking for an alternative. This I have found in SteckerPro APP. Downloaded and upgraded to premium and everything went fine. Although it is not so clear and the pictures are missing but this is still maintained. And now for the example have a AVM Fritz box. Just a secured VPN set up with DYNDNS what is at AVM vain. Now you just need the iPhone, setting the Enable VPN and after 2-3 seconds it is connected to the home. Start now the SteckerProAPP and turn your home sockets. Who does not believe that the light at home concerns can still specify a web cam and monitor everything. Listen to music from the NAS or VCR program now no problem. Yes as I said you have to be Spielkind and take a lot a lot of time. I hope it helps one or the other not so much time to waste with the facility. everything will be fine !!!
