KC868-A2 SIM7600 with Tuya GPRS not work

[WestfieldGhost]

Hello and thank you very much for the detailed DP overview.

I checked the product configuration and noticed something important:

In the Tuya product definition for PID n0tysl9oh0b6lfjh, the section “Product Standard Functions” is currently empty.
Because of this, Home Assistant can detect the device, but it cannot create any entities.
Home Assistant only reads standard Tuya functions, not custom DP functions.

All the existing DPs like
input1, input2, output1, output2, adc1–adc4, sensor1–sensor4, all_on, all_off
are available as Custom DPs, which is great — but Home Assistant unfortunately ignores custom DPs.

It is also important to mention that users cannot modify or add Standard Functions themselves.
Only the device manufacturer can define or update the Standard Functions for this PID.

If possible, it would be extremely helpful if at least a few essential functions could be added as Standard Functions, for example:
• Switch (mapped to output1 / output2)
• Boolean sensor (mapped to input1 / input2)
• Numeric sensor (mapped to adc1 / sensor1 etc.)

With only these basic standard definitions, Home Assistant would immediately recognise all required entities without any additional scripts.
This would make the KC868-A2 fully compatible with Tuya → Home Assistant setups, especially in LTE-only installations.

If this can be added in a future update or product configuration, it would help a lot — and I would be happy to test it.

Thank you again for your great support.

Hello again, and thank you for your continued support.

I just wanted to kindly follow up on the topic of Standard Functions.

As the DP list already exists, from my understanding it would only require assigning some of these existing DPs to Tuya Standard Functions (for example switch, boolean sensor, numeric sensor). No new DPs would be needed.

This small change would make a big difference, as Home Assistant can then automatically create entities.
Without any Standard Functions defined, the device unfortunately cannot be used in Home Assistant at all, even though the DPs themselves are available.

I understand that only the manufacturer can make this change, so I wanted to politely ask if this could be considered. I would be very happy to test it if needed.

Thank you very much for your time and help.

Best regards

now development team is very busy. next month if have free time, we can try to test it.

I really appreciate that you will look into this when you have time, and I am very excited to see the results next month.

Thanks again for your support!
