NTPClient VS ESPAsyncWebServer

I believe this is the ntp lib I'm currently using... https://github.com/arduino-libraries/NTPClient

Normally you sync the clock one or two times per day from the NTP server. Then you calculate the time from the time passed since last sync. If you are using the arduino ecosystem you can use this library. Otherwise you have to implement the NTP client and a timer based on interrupts.

I used This ntp library to insert accurate datetime for my recent ESP32 project. Super easy API, with support for each time zone. Not realistic if you already have a large program overhead.

By "NTP", you mean you used this library? Did you call the update() function in the loop()?

#include #include /* for time server: https://github.com/arduino-libraries/NTPClient */ #include /* for alexa */ #include /* for OTA */ #include /* for OTA and timeserver */ #include /* for OTA */ #include /* for Alexa: https://github.com/me-no-dev/ESPAsyncWebServer*/ #include "fauxmoESP.h" /* for alexa */ #include "credentials.h" /* Has the config for the wifi */ #include /* for the debug output via sockets: https://github.com/Links2004/arduinoWebSockets */ fauxmoESP fauxmo; AsyncWebServer server(80); WebSocketsServer webSocket = WebSocketsServer(81); //ws debugger will run on port 81

You can use the NTP library with the time library from Paul Stoffregen.

Use esp async Webserver https://github.com/me-no-dev/ESPAsyncWebServer

I don't know what you're doing wrong, but maybe you could change to the ESPAsyncWebServer instead of the fork you're using. Since me-no-dev works at espressif, it seems like that's basically the official webserver to use and I don't see that dvarrel did much good to it in their fork.

For something that's supposed to run at home and not be accessible from the broader Internet, you would do this by having your ESP8266 run as a WiFi client in your home internet and then using something like the EspAsynchWebServer library to make it a mini webserver than can receive requests from any browser in any of your home devices.

There is a library called ESPAsynchWebServer that will easilly allow you to run a webserver in your code on the ESP32 and ESP8266 chips with Arduino and if you check their simple example you can see it's reasonably easy to have the code for doing stuff on the hardware side (say, toggle the pin that controlls an LED) as part of the code that receives and processes HTTP requests.

Check out EspAsyncWebServer, it’s documentation will make clear how it would allow you to do this if you use it.

Go get EspAsynchServer. Check here.

I don't know what kind of Arduino you are using, but I would never try to implement a HTTP server that wasn't asynchronous. Typically using https://github.com/me-no-dev/ESPAsyncWebServer

I would make the ESP32 serve up a web page that displays the battery status, and also handle a button click that turns on or off the relay. You are looking at using https://github.com/me-no-dev/ESPAsyncWebServer
