IOT Arduino sketch for Mega/ESP32 w/ethernet for monitoring 16 relays on LAN by turn ON/OFF 16 LED

Arduino Uno/Mega or ESP32 w/Ethernet sketch for monitoring up to 16 devices with relays on LAN using3 methods: 1- IP ping; 2- AJAX response URL; 3- MQTT subscribe to topiks. The status of each monitored device must be displayed by switching respective LED- Red- OFF/NO RESPONSE, GREEN LED- STATUS OK, The 8 bi-color leds are connected to 2 Shift Register 74HC-595, and the pins 14, 12, 11 are connected to Arduino board. Also need to have keyboard Matrix 4x4 to send URL1 to relays on FIRST PRESS button and another URL2 On NEXT button press. Will be great to have a WEB SERVER and the HTML CSS Javascript Ajax page stored on SD-card, with 16 buttons with 2 status color GREEN- for ON status; RED- for OFF status a

and YELLOW for- FAILED STATUS. Also there are 16 relays that are connected to Arduino board pins thru another 2 shift registers 74HC-595;

Other details/features will be provided in chat and after starting job
