Happy to hear that you too were able to accomplish your goal with the garage door opening project. I too am thinking about trying to learn more but in the meanwhile, it’s so wonderful to have help from folks like Andy (Cobra). I am tempted to try to make a video for YouTube that gives all the complete steps, however, I’ve never done a video and not sure I can pull it off. It took days to complete the project and get my Sonoff’s to work then find instructions on wiring the RIBU1C to the garage door and the Sonoff only to find that I needed a momentary pulse to make the whole process automatic. Well, after a few days, it’s working like a champ and I only have less than $25 in the whole project. I will have the need to do this project again in a few months and expect it will take less than an hour. Needless to say I’m happy. Please let me know how you progress on future projects. All the best!
