  Request for 230VAC LEDs / Downlight
Posted by: benoitd54 - 06-17-2026, 06:08 AM - Forum: Development - Replies (5)

Hello, 

I'm currently building my house and i'm planning to be able to adjust the lighting in all my rooms (30 zones).

I came across your DIN rail modules, which I think are perfect. Great job!! 

However, a have a quick question: how can I dim 230VAC dimmable LED spotlights / downlight from 0% to 100% without any flickering and which the real 0% (using a triac?) ? 

Best regards

Benoit

  The watch shows the wrong time in standalone mode.
Posted by: rosnoteh - 06-15-2026, 08:06 PM - Forum: KC868-A series and Uair Smart Controller - Replies (1)

KC868-A16v3, firmware v3.25.0, battery 3,05V.
The watch shows the wrong time in standalone mode. The controller is connected to a local network without internet access. Time zone - UTC+3.
Turn on the controller. Click "Synchronize browser time".
The controller's clock shows the same time as the computer's clock. Turn off the controller, and then turn on the controller. The controller clock shows the time 3 hours later.
Turn off the controller again, and then turn on the controller. The controller clock shows the time 6 hours later.

"Is there a feature or logic in the Kincony A4S firmware that supports the following switch behavior: a single press toggles the light ON/OFF, while pressing and holding increases the brightness, and releasing then pressing and holding again decreases the brightness?"

  KC868-a6 2 analog outputs (DAC)
Posted by: bikovalexand - 06-14-2026, 10:26 AM - Forum: KC868-A6 - Replies (7)

Hello, I'm working on a project that uses both outputs of a KC868-a6 v1.33 controller (0-10 V DAC). I'm writing the program in OpenPLC Editor.
The signal on both outputs changes proportionally, but not from 0-10 V, only from 0-3.3 V. What could be the problem?
 I tried downloading the latest version of KCS (v.2.2.20) to the controller, connecting to it via WiFi, and changing the output values. They output from 0 V to 3.3 V. I understand the LM258DR should amplify the signal by three times? Perhaps it's not working?
Thank you

Monsieur l'administrateur;
vu que le KC868A8 est programmable par editor plc serait-il possible de faire de même avec son grand frere le KC868A16 ainsi que pour le kc868A32 car il semble que c'est les memes plateformes avec plus d'entrees et sorties sur le bus i2c en modifiant la boucle programmable en c++

  Tiny Alarm board after flashing seems to no longer working
Posted by: algaema - 06-12-2026, 01:29 PM - Forum: TA - Replies (7)

Hi Kincony,

I have tried to flash newer version firmware (tried KCS_KC_TA_V3.25.0.zip) from a Mac. Tried multiple methods, including the use of a Windows VM with the official tool, and web.esphome.io. But while both tool reported success, when I turn off and on the board it is not able to respond on network. I have even tried to use the method of removing power, pressing the DW button, and then attaching the power, and then used the official tool to copy firmware using a low (115200) baud rate, while the tool has reported success, after reset the board it is just not responding on network (I can verify that on the switch statistics, in which the "bytes sent" in switch has high values, however "bytes received" in switch is always showing 0, indicating that the Tiny Alarm board is not responding any packet at all. 

I have also tested to use USB C to USB A cable instead of a USB C to USB C cable as I see the youtube video is using one of that. 

May I ask how is there a way to troubleshoot a ESP32S3 board boot up message to see if the firmware is correctly copied?
