I have the same set up on 6 of my points. I had alot of problems with LS150 operating routes. In the end I fed each output from the Ls150 to a relay. The relays were connected to a CDU unit which then fired the point motor. I had to put a diode in series to each relay from the LS150 output. It was a fair amount of work but it has been reliable since.

Hi I have been using a prodigy  wi-fi unit for about 6 months now. Its one of the best things I have purchased for my layout. I have it connected to an early gaugemaster prodigy unit and have had no problems. I have it working with the android software. I still have 2 handheld wired controllers operating at the same time no problem at all once you have given the wifi app controller a unique address. You can not however programme with the wi-fi unit this still needs a handheld controller.

Hi I think connection 7 uses the three wires because it gives the option for connection 1 to be fed off a different circuit/ power district to number 7 if desired. I do understand your point about the extra wiring but the unit is designed to give more flexibility for more complex set ups if required.
