esp8266-esp32-sdk VS blynk-library

Check https://sinric.pro

Check this gitrepo out I used the relay one with the multiple relays for an Alexa controlled garage door - hope this helps https://github.com/sinricpro/esp8266-esp32-sdk/tree/master/examples

Code I used for multiple relays but sounds like you only need 1 - https://github.com/sinricpro/esp8266-esp32-sdk/tree/master/examples/Relay

https://blynk.io/ (you can find an example that uses their legacy API in one of my releases)

Like it says, to try and keep up with the changing well levels in the summer at my house, I put together a project to monitor well water levels and update a Blynk app.

From the source code found here: https://github.com/blynkkk/blynk-library/blob/master/src/Blynk/BlynkConsole.h

Check out Blynk: https://blynk.io

I have an Arduino Mega 2560 with an ESP8266 module connected to it via Serial1 as outlined in https://github.com/blynkkk/blynk-library/blob/master/examples/Boards_WiFi/ESP8266_Shield/ESP8266_Shield.ino - basically, this sketch works perfectly as is, but I have it personalized, of course.

That Blynk library sucks badly... it's obviously NOT written with ESP8266 in mind, simply grossly hacked from an Uno to sort-of-work. I see a few places in the header file alone where it can hang and cause a WDT, and the 'ping' that's printed is buried somewhere else in the library, undoubtedly another poorly-planned while() or if-else-hang.

Agreed about google and would add clarity. In the field of IT clarity is critical. If OP had said blynk.io, the .io would have clicked with me that it was a web site. Another guy just asked about PS/2 - I thought he meant the keyboard/mouse interface. Others twigged that he meant Playstation 2.
