Hi

I have a situation when Home Assistant starts all my entities from 2 COLB modules have 'unknown' values. That's because the COLB modules are note sending periodic state messages ore they have no availability topic.   They are sending data only on state changes. That's could be critical in some situations like climate control. 
Example:
Turning on or off the heating in some rooms based on windows states. If a window in a room is closed then turn on the heating in that specific room. Now When HA starts the state of the window will be unknown so the heating won't start. That's only a banal example but in some critical scenes this could be an issue.
Proposed solution:
Make COLB to periodically (ex: every second) send stats data or when HA starts make some request to COLB topic to provide current sensor states.

This could massive improve the device reliability. Is it possible? Thank you.

Hi Team

In Lesson 3 - of Home Automation Power distribution Box - below is the link

New tab (kincony.com)

Kindly confirm the What is the "Amps " used for ( 12V DC contactor) in Hardware lists ?



Thanks & Regards,

KC828-Server has two ethernet
I installed Debian on CM4 with ipV4 192.168.1.128
another ipV4 is 192.168.1.129, work mode MQTT

My problem is KC828-Server can be pinged from 192.168.1.128 to 192.168.1.129, but unable to respond mqtt command, neither to login until I do a restart then everything works fine.
This happens many times in a day, and I can't figure out how to solve it other than restarting the module.
Please advise.

Hi,

The Uair case seems like a cool solution for DIY room sensors of any type but I'm not sold on the default PCB which is pretty expensive and contains features I do not need (like GPRS). However it seems to me that a case with nothing in it (eg no usb connector or LED) is also less than ideal as getting everything built into it and aligned is a pain.

Is there a barebones PCB option? For example the PCB  + USB B/C connector + break out header for the USB terminals? That would mean the PCB would be very cheap, but installing my own ESP32 and sensors would be easy....

Thanks!

CP.

hello all,
I am just new to the products of kincony and have a question: I am looking for a board with at least 8 relays and with the possibility to connect a few 1-wire sensors (temperature and VOC). If I saw it right, the KC868-A8 is exactly the right one for what I am looking for. Also price wise. Or ?
thx,
greatings

Let me present here my KC868-A16+16R* model to control my household lightning
+16R in name stands basic KC868-A16 have grown with additional 16-channel relay board on top of existing outputs.

Reason why I needed this is I have in my house impact relays what turn lights on/off and to control those I have low voltage push buttons what have led indicator to present light state. 
KC868-A16 digital inputs are reserved for button inputs
KC868-A16 Mosfet outputs are reserved to present output state in buttons
Additional 16 relays are to control impact relays as those require 12-24Vac 

Also I have here and there some smart lights what need to be constant AC, so for those channels impact relay is always in line powered positions and lights are controlled over the air, but for traditional dummy lights impact relays are controlled with that additional board relays. There's also failsafe that is Home Assistant or LAN is unreachable all lights are controlled with on/off function like traditional lights.

I'm running ESPhome in board  

16-channel relay board is basic 12Vdc voltage board what can be found everywhere like from Amazon or Aliexpress. To able control relays I had to add pcf8575 16 channel I2C IO extender card to relay board and wire it to KC868-A16 board I2C pins. Also couple of other modifications needed to get board fitted to same enclosure than  KC868-A16. Those were to move large electrolytic capacitor, power connector and pins headers to bottom side of circuit board. note in a picture power connector is still in original place
Also KC868-A16 enclosure got some modification, like trimming a skirt, adding slot for the board and slots to reach connector screws from top. Need to add some finishing touch to enclosure for sure

she might not won beauty contest but she rock!

edit: thank you for uploading images.

I am embarrassed to ask this and have flashed many ESP32s with far more complicated code but I am just trying to load one of the demo sketches provided by KinCony just to test my 868-A6. 
 I get this:

I am using "cu.usbserial 14620" drivers and they work with my ESP32's. Can anyone tell me what might be wrong?

How can the power be calculated for the SMART control system, considering the use of a 12 volt DC source for the following components, all of which operate on 12 volts DC and 
HOW calculat the total current ?

number  4  of KC868-E16V2            ( total 64relay )
number  2  ofof H32B PRO              ( total 64relay )
number  2 switch module boards      ( total 64 switch ) 
number  3 contactor 45A 12v dc )

I tryed to use this configuration for tasmota

https://templates.blakadder.com/kincony_...3e5fOFiJP6

But it does not work for me

I did configure a IR receiver on GPIO 32 and it seems to receive something when I press a button on my remote control.
However it also receive with an UNKNOWN protocol when I do not press anything.

I also have a RF remote control, and I cannot receive anything from this one.

Is the GPIO32 the one for IR Receive ?
What is the GPIO Number for RF send and RF receive ?
