/*********************************************************************************************\
* Chinese BL6523 based Watt hour meter
*
* This meter provides accurate Voltage, Frequency, Ampere, Wattage, Power Factor, KWh
* To use Tasmota the user needs to add an ESP8266 or ESP32
* Three lines need to be connected via 1KOhh resistors to ESP from the main board(RX,TX GND)
*
* Connection Eg (ESP8266) - Non - Isolated:
* BL6523 RX ->1KOhm-> ESP IO4(D2) (Should be Input Capable)
* BL6523 TX ->1KOhm-> ESP IO5(D1) (Should be Input Capable)
* BL6523 GND -> ESP GND
*
* Connection Eg (ESP32) - Non - Isolated:
* BL6523 RX ->1KOhm-> ESP IO4 (Should be Input Capable)
* BL6523 TX ->1KOhm-> ESP IO5 (Should be Input Capable)
* BL6523 GND -> ESP GND
*
* To build add the below to user_config_override.h
* #define USE_ENERGY_SENSOR // Enable Energy sensor framework
* #define USE_BL6523 // Add support for Chinese BL6523 based Watt hour meter (+1k code)¸
*
* After Installation use the below template sample:
* {"NAME":"BL6523 Smart Meter","GPIO":[0,0,0,0,7488,7520,0,0,0,0,0,0,0,0],"FLAG":0,"BASE":18}
