  KC868-A16S GSM/LTE Connection Issue - CSQ=99 (No Signal)
Posted by: vardan - 01-26-2026, 09:09 AM - Forum: KC868-A16S - Replies (1)

Problem Summary
I cannot get network registration on my KC868-A16S board. The modem consistently returns CSQ=99 (No Signal) and fails to attach to GPRS.
________________________________________
Hardware Setup
• Board: KC868-A16S (ESP32 with integrated GSM module)
• SIM Card: Active SIM with data plan (tested working in phone)
• Antenna: LTE antenna connected to the antenna port
• Power: 12V DC power supply

Software Configuration
Platform
• PlatformIO with Arduino framework
• ESP32 Dev Module target
• TinyGSM library v0.11.7
Pin Configuration (from our code)
// GSM Module Pins
#define PIN_GSM_RX 32  // ESP32 receives from modem
#define PIN_GSM_TX 33  // ESP32 sends to modem
#define PIN_GSM_PWR 23 // Power pin (unused currently)
APN Settings
#define APN_NAME "internet"
#define APN_USER ""
#define APN_PASS ""
________________________________________
Initialization Code
// GSM Modem Init
SerialAT.begin(115200, SERIAL_8N1, PIN_GSM_RX, PIN_GSM_TX);
delay(3000);
Serial.println("Initializing GSM modem...");
modem.restart();
// Check Signal Quality
int csq = modem.getSignalQuality();
Serial.print("Signal Quality (CSQ): ");
Serial.println(csq);
// Wait for Network
if (!modem.waitForNetwork(15000)) {
    Serial.println("Network registration FAILED");
} else {
    Serial.println("Network OK");
    // Connect to GPRS
    if (!modem.gprsConnect(APN_NAME, APN_USER, APN_PASS)) {
        Serial.println("GPRS Connect failed");
    }
}
________________________________________
Serial Monitor Output
Initializing GSM modem...
Signal Quality (CSQ): 99
Waiting for network... FAILED (will retry in loop)
Network lost. Reconnecting...
Network unreachable
CSQ=99 means "Not Detectable" according to AT command specifications.
________________________________________
What I Have Tried
1. ✅ Verified SIM card works in mobile phone
2. ✅ Tried different APN names ("internet", "")
3. ✅ Checked antenna connection
4. ✅ Tried baud rates: 9600, 57600, 115200
5. ✅ Power cycled the board multiple times
6. ❓ Not sure if there is a PWR_KEY or RESET pin that needs toggling
________________________________________
Questions for KinCony Team
1. What is the GSM module model on the A16S? (SIM7600, SIM800L, A7670C, or other?)
2. Are the TX/RX pins correct? (We use GPIO 32 for RX, GPIO 33 for TX)
3. Is there a power-on sequence required? Does the GSM module have a PWR_KEY or RESET pin that must be toggled before use?
4. What baud rate should we use? (Currently 115200)
5. Do you have a working demo code or .bin file that we can flash to verify the hardware works?
________________________________________
Additional Information
• Wi-Fi connection works perfectly on the same board
• All other I2C devices (PCF8574, RTC, sensors) work correctly
• The board was purchased recently and appears undamaged
Thank you for your help!

  F16 tuya reverse sw. function missing
Posted by: Karlis_LV - 01-22-2026, 08:21 PM - Forum: F16 - Replies (5)

Hello,
Please help me with some information. I have two questions about the KinCony F16 module (software nr. V3.18.0)  and Tuya.
I have connected simple momentary (non-latching) switches to the input channels to control lights. The switch has no fixation: one press turns the light ON, the next press turns it OFF.
Question:
Why, in the Tuya app (Simple Device Scenario),  I can configure the “Reverse Switch” function only for channels 1–6, while the other channels only have ON / OFF options.WHY?

[Image: tuya-kincony-f16-switch06.png]





Question 2:
Why is there such a noticeable delay / latency between pressing the button and the relay switching ON? It is very uncomfortable to use.
Is this a Tuya cloud-related issue, and if I use a local server (local control), will this delay be resolved?

  Relay board wiring error?
Posted by: Elgatoguiri - 01-22-2026, 02:58 PM - Forum: KC868-A series and Uair Smart Controller - Replies (3)

Hi,
I've wired the controller up with a relay board but it acts a bit strange.
All the MOSFET LEDs are on at all the time.

The relay board uses 3 pins for power options. It is set to VCC JD-VCC. 

The relays work when controlled from homeassistant through esphome with a little quirk. When homeassistant switches are off the relays turn on. So it works the opposite way.

The relay board gets its own power and ground.

Are the LEDs supposed to be on at all the time when a relay board is used ?

Is the opposite switching direction a configuration error or I wired something up incorrectly?

This is my esphome config for the board:

Purchased a Kincony Z1 controller last week.

Located the newest firmware. v3.18.0

launched the flash download tool 3.9.2

Settings at esp32s3, usb

My com port is COM4.

open my firmware v3.18.0, all default settings.

I hit "START", and nothing..  ??

Is there a button that I have to hit on the Z1 unit?

Couldn't find the Z1 forum here, sorry if in wrong area.

Thank you, looking forward to this Z1 being added to my system.

  N31 energy value integer values
Posted by: np.nagypeter@gmail.com - 01-19-2026, 12:38 PM - Forum: N30 - Replies (1)

Dear Support Team,

I am writing to request technical assistance regarding the Kincony N30 power monitoring controller. I am currently using the device with ESPHome via the Modbus interface (reading the BL0910 chips).

While the device is functioning correctly in terms of connectivity, I have encountered a significant limitation regarding energy consumption data.

The Issue: The Modbus energy registers (e.g., addresses 140, 142, etc., for Chip 1) only return integer values. Even when the sensors are configured to display 3 or more decimal places in ESPHome, the
data received from the device is always a whole number (e.g., 0.000 kWh, 1.000 kWh).

Technical Details:
Device: Kincony N30 (ESP32-S3 with W5500 Ethernet).
Interface: Modbus RTU over UART.

Observations: The Voltage (V) and Power (W) registers provide high-resolution data with correct decimals. However, the Energy (kWh) registers do not seem to transmit fractional increments.

Log evidence: My logs confirm the device is sending states like 0.00000 kWh even when a load is active, and only jumps to the next whole number after a full kWh has been consumed.
Example log snippet: [sensor:135]: 'bl0910_1_energy_1': Sending state 0.00000 kWh with 3 decimals of accuracy

My Questions:
Does the current firmware of the Kincony N30 support fractional energy readings (e.g., Wh or 0.001 kWh increments) via Modbus? Is there a specific multiplier or a different register address I should use to obtain higher-resolution energy data? Is there a firmware update available that addresses this resolution limitation?

Thank you for your assistance!
