I tried connect ESP32 Cam to KC868-A2 via I2C but doesn't work, can you help me please?
SDA (GPIO4) on the Kincony board to SDA (GPIO14) on the ESP32-CAM.
SCL (GPIO16) on the Kincony board to SCL (GPIO15) on the ESP32-CAM.
GND on the Kincony board to GND on the ESP32-CAM.
3.3V on the Kincony board to 3.3V on the ESP32-CAM.

initialization in mycropython:
i2c =machine.I2C(0, scl=machine.Pin(16), sda=machine.Pin(4))

Can you advise how we can set up KC868_A16 working with RS485 by Arduino IDE? Thanks

In the specification https://esphome.io/components/ota.html it is stated "In that mode, all components are disabled and only Serial Logging + Network(WiFi or Ethernet) + OTA are initialized, so that you can upload a new binary ."

I have an A16 integrated with HomeAssistant. In ESPHome  new version of YAML can be downloaded to the A16 without any problems via USB cable. Update via Ethernet cable (same network, WiFi not available) ends with an error.

Is it possible to install the update via Ethernet? Please could you send me the OTA code for the YAML file of the A16 device?

Hi all!

What is the maximum cable length that can be used between the KCOM and each input terminals? Would 50 metres of AWG24 cable (0.215mm2 / 14/0.2mm stranded) be OK? How can we calculate the acceptable voltage drop? Thanks.
