I will have this PCB working with home assistant.(you can make it running using other soft: Nodered/ Arduino IDE/ micropython...what you wish)
I have made some modifications to get 2 more temperatures readings from 18B20 waterproof sensors + DHT22 (temperature/humidity)
This PCB is working with home assistant to get temperatures, humidity, state of relays and activate relays to turn on 12V leds in my case through WIFI connection.
In summary: Home assistant is running in a raspberry pi4B, connected to my Wifi network.
This PCB is connected to my wifi network using the ESP32 on this board. (ESP32 should have in theory a greater wifi range compared to the standard ESP8266)
I can access home assistant using my phone connected to the same wifi network to get informations (relay states/ temperatures/ humidity) and send actions (turn on off the 12V bulbs)
