+### Important notice:
+This code is supposed to work with all kinds of ESP32 devices (ESP32, ESP32-S1, ESP32-S2, etc.), but minor adjustments might be needed. Anyway you will need to adapt the pin numbering to your board.
+We successfully tested the following devices:
+- AZ Delivery ESP-32 Dev Kit C V4
+- ESP32-S2-Saola-1
+
+The relay module is also interchangeable with other relay modules you can buy on Amazon. The code is written in a way that it should be easy to adapt to other modules. Here it is important to add that this code is written for active-low relay modules.

 ### Quick start

 #### Hardware Setup
 Connect the INA219 module according to the schematics. 
 Connect the relay module to the ESP32. The relay module should be connected to the pins GPIO2 and GPIO15 of the ESP32. The relay module should be powered by an external power supply. The relay module should be connected to the power circuit you want to monitor and control. The INA219 module should be connected to the power circuit you want to monitor. The INA219 module should be powered by the ESP32.
