I have been looking on-line and watching some YouTube videos.
Would this combo work in my musical boxcar?
EBay :DC5V/DC5V-12V Self-lock Smart WiFi Wireless Switch Relay Module APP Control with a USB rechargeable 9V like EBay: 142545740433
Could I use it when my tablet/phone is connected to the MTH wifi, while I'm connected to my DCS explorer? Could I just switch apps?
OR I want to connect to a ECHO at some point would this one work? EBAY:Sonoff WiFi Wireless Smart Switch Relay Module Inching/Self-L
I also seems to me that you can command multiples of these in the app.
