I did a video series showing how you can use the app, the schematics you can follow, and also put a code example, youtube video playlist: https://bit.ly/34qoYDY
Yes, most of them have a similar working principle, I tested it with the one I showed in the video, but you can try it out with others if you have one, and show us the results.
Will other type of receivers and transmitters work? In my country we don’t have access to WL-102-341 modules.
