Hydroponic Automation IoT help needed

Other Hardware Home Automation
1

Hello Friends,
Good Day

I am doing a project on Hydroponic Automation
My hardware list are:-
Arduino Mega 2560
3.5" LCD TFT
DHT22 Sensor
DS3231 RTC
DS18B20 Temp. Sensor
pH, EC, DO (not connected yet)
8 Channel Relay (to control light, fan, air & water pump)
L298P Motor Driver (to operate dosing pump)
works fine with my sketch(still needed some correction)

  1. to Monitor & control some device remotely i bought ESP32s & Arduino MKR 1010 Wifi
    I installed Home Automation Virtualbox, connected and works i get data of DHT22
    when i connect to my ESP32 module but how to get data and control relay of Arduino Mega
    connected device.
  2. Arduino MKR 1010 want to communicate and publish sensor data of (Ardduino Mega connected

device) to Arduino IoT Remote (Mobile App) and control relay of mega.
3. i am unable to communicate between Arduino Mega & Arduino MKR, i trield many ways, many sketches (downloaded only, as i am new to Arduino & IoT) connected both device as per specification and TTL (3V3 Logic Shihter TXS0108E Module) i tried TX, RX, SDA SCL. but failed to communicate between 2 Arduino baords.
Looking for a help ASAP
Thanks in advance

Have a look here and see if this helps, even though they are using different arduinos, the overall concept is similar and may help get you closer to resolving your issue

Also something use to possibly look at is the NodeMCU boards, you can load your sketch on that and has wifi built in, i use those for my home automation along side of other software to manage the automation and works great..
