Great project! I have 2 questions for you:How did you know the balloon landed on Palomar mountain?And do you need some kind of permission to launch a balloon this high?
Thank you so much for your comment.I was not sure if a breadboard could be used with voltage as high as 230V.Using the 2nd output of the Esp for another relay is possible and is a good idea.I thought about using a battery to supply 5V, but I didn't see the utility: the 5V can be supplied by the ac/dc converter, and the 5V will continue to be supplied until there is a power failure. And if there is a power failure, I'm not going to be able to turn my light on anyway, so I don't care if I cannot control my board.Yes the software was made for time delay. The rtc is provided by the blynk server, and the time information is sent from the app to the board through virtual pin v3.Best,
Hi,This is an interesting question, I think it has been discussed on the esp8266.com forum: http://www.esp8266.com/viewtopic.php?p=1551Best,
I'm glad you asked that. The reason I did this project is because none of my lights are connected to a wall switch.Using the phone to turn them on/off is temporary, I plan to make a few portable switch, connected to a battery to control them all. But this will be another project that I will publish.Thank you for your interest,
Thank you for your comment. I didn't know about transients. Do you think that this protection might already be included in the relay board?Best,

Thank you for your suggestions.With this project, if you need to add a wifi SSID and pass, you need to open it, take the ESP off, reprogram it, and put it back. Feeding the wifi through the app would be really convenient.Adding a button would also be interesting, in case you don't want to take your phone out of your pocket. And it's possible to use the GPIO0.Thanks for your interest in this project!
