KC868-A4 remote control over the Internet.

first way: you can order one tuya licence from kincony and use "KCS" firmware , so that can control A4 board's relay ON/OFF and monitor analog sensor and DAC by internet. DS18B20 not support by tuya app not, but in furture we will update "KCS" firmware.

another way, if you can program code, you can write arduino code and use router's port forwarding function without cloud server.
