  KC686-A6 error on upload
Posted by: sm4l - 04-14-2025, 06:33 AM - Forum: "KCS" v2 firmware system - Replies (8)

Hi everyone, I'm having trouble uploading data to my KinCony KC868-A6 v1.3SP board and would really appreciate some help.
This morning I got home and, to my disappointment, the board wasn’t working. I finally had time to try uploading my firmware again, but it’s not working.

  • The board’s LED is on as usual.
  • The USB connection is recognized by my computer.
  • However, in the SPDownload tool, the board info doesn’t appear — it seems like it’s not being detected properly.
  • I’ve tested four different USB cables (all confirmed to work for data transfer on my Samsung smartphone).
  • I don’t have any sensors connected to the board right now.
  • There were no power surges or electrical issues today, so I doubt the ESP32 is fried.
Has anyone experienced something similar or have any ideas on what I can try to fix this?
Thanks in advance!

  all relay controllers selection wizard
Posted by: peacemakerv - 04-11-2025, 10:04 AM - Forum: Schematic & diagram & Dimensions of KinCony PCB layout CAD file - Replies (5)

Hi, All

1) Is there any database (or table) of all controllers to choose the interfaces i need ? Some cross-reference table.

2) Now i need all docs (schematic at least) of the 3-pin relay controllers of all possible channels qty. 4\8\10\12\16\24\32\64 pcs of channels, but with 3-pins NO\NC\COM. 

Separate product articles on the web-site are not unified structure, it needs to check each - maybe can you help to get all relay models sch together ?

  Driver recommendation for 24V LED strip
Posted by: TMaYaD - 04-10-2025, 10:41 PM - Forum: DIY Project - Replies (7)

Hi
I want to control and dim 24v LED strips using a controller like KC868-A4S. I'm looking for any recommendations for drivers.

I've tried Meanwell ELG-200-24B. But it doesn't turn off completely.

Any inputs are appreciated.

  KC868-A4S and meanwell ELG-200-24B
Posted by: TMaYaD - 04-10-2025, 10:25 PM - Forum: KC868-A series and Uair Smart Controller - Replies (3)

I'm trying to use meanwell ELG-200-24B to drive 24v LED drive strips using A4S and the LED does not completely turn off. When I checked, there is ~0.58V across the analog output and ground.

What am I doing wrong?

  IoT Weather Station - Class B
Posted by: egionet - 04-10-2025, 01:26 PM - Forum: Customer project example - Replies (1)

This is an ongoing project, and I plan to deploy the station in a month or so.  This setup leverages class B scientific grade meteorological instruments polled over serial MODBUS.  The controller enclosure's environment is monitored by a Kilcony RS-485 temperature and relative humidity RTU, and barometric pressure is monitored by a BMP280 over I2C.  The code base is in C i.e. ESP-IDF, and a sample implementation is available here.

Telemetry data model:

Code:
typedef struct rpu_telemetry_data_s {
    uint64_t    timestamp;
    struct rpu_s {
        char        network_id[16];
        char        name[32];
        uint32_t    system_uptime;
        uint64_t    reboot_timestamp;
        uint16_t    reboot_counter;
    } rpu;
    struct atmospheric_s {
        float                   spot_wind_speed;
        uint16_t                spot_wind_direction;
        float                   avg_wind_speed;
        uint16_t                avg_wind_direction;
        float                   max_wind_speed;
        uint16_t                max_wind_direction;
        float                   air_temperature;
        float                   relative_humidity;
        float                   dewpoint_temperature;
        float                   barometric_pressure;
        float                   precipitation_rate;
        hyrs2e_precip_types_t   precipitation_type;
    } atmospheric;
    struct ground_s {
        float   soil_temperature;
    } ground;
    struct cabinet_s {
        float   air_temperature;
        float   relative_humidity;
        float   dewpoint_temperature;
        cabinet_door_states_t door_status;
    } cabinet;
} rpu_telemetry_data_t;

Telemetry data is uploaded to ThingSpeak once a minute over MQTT when connected to a Wi-Fi network.

  How to uses sensors with v3 firmware
Posted by: twostar - 04-10-2025, 01:23 PM - Forum: "KCS" v3 firmware - Replies (13)

I'm having trouble using DHT22 sensors with the v3 firmware, with the v2 firmware you just set sensor ID 1, type DHT22 and it worked.  With the v3 firmware it looks like you need to set a GPIO address but there's no indication for what this should be, and trying the first one, 47, bricked the board. How do you set up a DHT22 (or any other sensor) on the 1-wire GPIO ports?
