Incoming SMS not reported via MQTT - JCh - 02-21-2026

Hello,
I am using Kincony G1 with SIM7600 module fw KCS 3.19.1 and MQTT integration.

According to the forum documentation, incoming SMS should be reported via MQTT STATE  topic in this format:
Code:
{
"sms_recv": {
"phone": "+8612345678901",
"content": "example"
}
}


Unfortunately, I am unable to get this working.
My setup:
  • Device: Kincony G1
  • GSM module: SIM7600
  • Firmware: KCS v3.19.1
  • MQTT broker: working correctly
  • Home Assistant 2026.2.3
  • Topics: 
     G1/XXXXXXXXXXXX/SET -  working (sending SMS works)
     G1/XXXXXXXXXXXX/STATE -  working (inputs, call_ring, etc.)
What works:
  • MQTT STATE reporting for inputs (input1…input12)
  • Outgoing SMS via MQTT (run_sms)

What does NOT work:
  • Incoming SMS and calling are not reported to MQTT
  • No (sms_recv) payload is published to STATE topic

Tests performed:
  • Clean SIM card (no stored SMS)
  • Very simple SMS content: TEST (no diacritics, no multipart)
When an SMS is received, no new MQTT message is published at all.

Question: Is sms_recv currently supported on Kincony G1 with SIM7600 in official KCS v3 firmware?

If yes:
  • Is there any additional configuration required?
  • Is SMS TEXT mode (AT+CMGF=1) required and handled automatically by firmware?

If not:
  • Can you confirm that incoming SMS → MQTT reporting is currently not supported / disabled for this hardware?
Thank you for clarification.
