[admin]

Here is "KCS" firmware for KinCony KC868-A series (ESP32) board.
How to download and use, online guide: https://www.kincony.com/esp32-kcsv2-firmware.html

v2.2.7 improvement:
1. Fix the problem that the mqtt command does not support the simultaneous processing of multiple commands
2. Fixed mqtt instructions run_rf, run_ir, set_beep returning wrong json format

for example:

{"output1":{"value":true},"dac1":{"value":250}}
   
   

{"output1":{"value":true},"output2":{"value":false},"output3":{"value":true},"output4":{"value":false},"dac1":{"value":125}}
   
   

these can write in one payload.
