Good afternoon! I ran into the following problem: when connecting a temperature sensor DS18B20, it shows a value from 0 and more. It does not show a negative temperature.  What could this be related to? The board is KS868-A4, Software Version v2.1.9.  The sensor is now installed outside the window. The temperature outside is "-7" C. The length of the sensor cable is 0.7 m. I have two such sensors and both give the same readings.

Hi,

I just received my M16-v2.1 board and will use it with 10A and 20A 0-1V clamps. New to the forum :-)

I'm on a 3x400V+N network and connected L1, L2, L3 and N to the terminals to measure the voltage.
But the voltages that are reported seem to be too low.


I also have a Zennio Kes Plus KNX device that also measures voltage and power consumption. (top 3 values in image below).
I also tried 2 different multimeters and get nearly the same readings as the Zennio (and I measured on the inputs of the M16)

But the M16 readings are 8-12 volts lower.



Is there a way to calibrate the voltages?
I'm using home assistant with ESPhome

If not: can I use the voltages from another home assistant entity (my Zennio) and use these?

After that I would like to start calibration of the CT-clamps: is it advised to do individual clamp calibration for each connection?

Regards,
Nick

Hello,

Thank you for the great boards that you build, the looks very quality and the features are amazing !

I'm testing the future setup of my home, I bought KC868-D16 for light dimmer and some Relay SSR Voltage Regulators.

I know that you always recommend the following relay (https://www.aliexpress.us/item/3256801518590551.html) to use with your board, but I it's much more expensive than alternatives I've found.

I have searched for the same spec:
  - 0-10VDC Control Input
  - 0-250VAC Output


There's any additional spec that I should pay attention when looking for alternative ? Because the relays that I've bought are not working, when I change the dimmer bar their led don't even power up....

The pictures of relays are attached.

hello. I want to connect the encoder to the inputs d1-d4. What is the maximum frequency at which they can work?

Hello,
I would like to know if the card can be powered by 24 V

Many thanks
Best regards

Hello,
I would like to present the following problem.
I have four Kincon controllers of the following type:
2 pcs.  KC868-AIO
2 pcs.  KC868-A8
Problems related to loss of communication in one KC868-A8 controller
The other drivers do not have this type of problem and work stably
Both KC868-AIO controllers have the same network configuration saved in the controller memory.
I wonder what could be the reason for the loss of Ethernet communication if at the same time the other controllers are working stably.

Hello!
I was trying to find which ins is connected to S1 and S2 buttons of KC868-A4.
On my board isn't specified which one is reset.. and the another one, in which pin is connected.
May I use one of this two pins as button? Is a pullup or pulldown resistor ?

Hello, I am having trouble connecting sensors to the KC868-A16S module. Can you please send me a wiring diagram for the following sensors: 
1- A 220v motion detector PIR with 3 wires on the KC868-A16S module. (Can I connect the output of the 220v sensor with the dry contact input of the KC868-A16S module?)
2- A water level sensor XKC-Y25-V PNP with 4 wires. 
3- A water level sensor XKC-Y25-V NPN with 4 wires. 
4- A gas leak alarm sensor 4 wires . 
5- A smoke detector 4 wires .

Hello all, can someone please help me with a code that I can use KC868-A8S to read and write to normal Arduino using modbus...
