I have 2 tuya adapters which connected to H32B and H32L.

Both tuya adapters are connect by wifi.

When my router turns off then i turn it on (sometimes because power outage), then I see the controllers in tuya app are offline. 

When I push the reset button on the Tuya adapters, then the controllers become online in tuya app.

Is there a way to let the controllers become online automatically after the router turns on again, without push rest button on Tuya adapter ?

i got this issue

what's wrong?
I already changed more displays , try invert sda/scl, try 3.3v and 5v also...

I have a kinocny F16. Please tell me, I don't understand how to connect a heated floor and a thermostat to this controller to control an electric heated floor? Can you draw a simple diagram to understand the connection?

And also a question, I have 10 KinCony TS Tiny RS485 SHT30 coming to me, will I be able to connect everything to one F16 controller?

I'm going to use KSC v3 to control the heated floor and KinCony TS Tiny RS485 SHT30 sensors.


Thansk for you support and very nice product.

I noticed that Kincony also has RS485 communication, it is more difficult, but it seems safer to me without dependence on the local network.

Does anyone have experience with this integration please?

Maybe first question it's Modbus RS485 or "RAW" RS485?

I am new owner "KC868-A32M 32 Channel ESP32 MOSFET Board".
I'm currently struggling to see it on the network at all, it may have DHCP set up, but I can't see it anywhere on the network after connecting.

Good afternoon, I have a problem. with  KC686-A6 and KC868-A16 panel


I installed new firmware,I connected everything and everything works.
but,On the web browser and on the phone  Only relay outputs work fully!!
like INPUT or ACD NOT!!! There are no errors, nothing.That is, they can be registered and something can be done with that.
You can make whatever you want with programming that.
the phones are not pressed either
Also, when connecting buttons or sensors, they do not give any sign of life.
Maybe there is something missing in the code Well, as I understand it, the firmware has everything included, just like in the video on the official website

What could be wrong or where is the problem please tell me ?

Thank you very much have a nice day

Hello Admin,
I’m using the ESP32-S3 2-channel relay module – KC868-A2v3 with the GSM SIM7600E, and I tried the IFTTT method to control the relay. However, when I call the number of the SIM card inserted in the GSM module, it doesn’t answer automatically so that I can type in the code with # to turn the relay on or off. Instead, the call hangs up after a few rings.
I’ve attached screenshots of my configuration using the web browser.
Could you please guide me on what I might be missing or doing wrong?

Looking forward to your reply.

Thanks in advance.

With regards,
Hamshini

My KC868-server16 refused to boot, and it is just blinking as shown in the video. I have inserted the SD card into the standalone Raspberry Pi 4 module, and it booted. I am wondering what to do next. I have tried several times to reboot without success.

Hi everyone, I'm new to Kincony products and this forum. I recently bought a Kincony A2V3.1 board to test these products and their integration with Home Assistant.
Once the board arrived, I connected it to my router via LAN cable, but I cannot see any IP address on the A2V3 screen, nor can I find it on my network.

For this reason, I tried to reflash the KCS v3 firmware using ESP32 Download Tool V3.9.2 and entering download mode (turn off → press S2 button → turn on power → release S2).
However, when I press "start" on the ESP32 Download Tool, I get this error:

I'm writing my own program in C/C++ and I was wondering if the interrupt pins of the MCP23017 chips are connected to the GPIO pins of the Raspberry Pi? If so, which GPIO pins are used?
