How use SIM800 on KC868-A2

[Mihanic]

I have a SIM800 modem. How can I transfer data via GPRS to my home assistant server (for example MQTT) or the Tuya cloud if I do not have an Ethernet and WiFi connection.
I use firmware 2.2.7 - there you can only SIM7600

KCS firmware only use for SIM7600 4G module, not use for SIM800L, SIM800 2G module not support MQTT.
