Hi,

I have my KC868-AIO connected to KC868-E16-V2.
It is connected via Ethernet to Home Assistant server.

It was working smoothly, was working fine after many power off situations at home.
Today I had to reset all electricity power at home off and after couple of seconds on and I lost my KC868-AIO - its ethernet does not work (based on the lights on the ethernet plug). It does not have any IP, scanned all the IPs in the local network, probably the ESP32 board died?

I do not know how to debug my KC868-AIO to see any error messages and to see if the ethernet board on KC868-AIO is broken?
Or do you have any experience what might be the issue? Could it just resetted to factory settings? In the factory settings it would not have ethernet output working?

Do you know how to debug it via USB? What tool to use to see the logs? What tool to see the errors? And check if ESP32 is alive?

The smallest RS485 IO Module -- KC868-HAv2 module. size 3cm*3cm. let your switch panel and dry contact sensor convert to RS485. KC868-HA RS485 INPUT & OUTPUT plugin for ESPHome, easy integrate to home assistant. You can add everyone KC868-HA board with 6 digital input ports and 6 digital output ports to home assistant by RS485.

Hello,  I am new to the forum and new to DIY. Hopefully I can get some guidance from the seasoned DIYers and Kincony admins.

I am building 2 houses that are coming up soon for electrical wiring. I am considering Kincony products instead of the wiifi router for home automation, but I have some questions that I hope something in this forum can help with.
 
The houses are fully 100% off-grid solar, and battery power as they are being built not very close to any grid power.
 
I am considering Kincony products and some Zigbee devices for home automation.
 
First, how does Kincony work with dumb light switches? Ex. Can Kincony turn off a light using automation and the light be turned back on via switch?
Second, what happens after a power loss? Does the system come back with everything working?
Third, if used in conjunction with ZigBee devices, does the devices need to be reprogram when using Kincony to control the down stream device? Ex. Kincony controls a device circuit like a light switch, in between the Kincony hub and the device is a ZigBee device, does this device loses power and require program?
Fourth, will wireless connected devices lose programming if controlled with Kincony?
Fifth, how does Kincony interact with other smart devices or technology such as wireless, Bluetooth, Zwave, ZigBee, etc.?

House:
·         65+ lights control by dumb light switches
·         4 mini split ac conditioning – automated to work only during solar power
·         A series of motion/pir sensors
·         Motorized blinds
·         Dimmable lights
·         Multiway light switch
·         Water level monitor
·          
I want voice control (Alexa, Google, and local), app control, browser control using tablets, using Home Assistant.


I am considering these products
KC868-Server, KC868-E8, MCB breaker, and other components.
 
Am I missing anything? Can Kincony do all this without any issues?
 

Hello, I have a KC868-E16S board and installed the firmware KCS V2.1.9 on it. I connected a water level sensor that operates in the range of 0 to 5 volts and 0 to 0.7 meters.

I tested the sensor by placing it in a water tank with an actual height of 41 cm. 

I noticed that the sensor reads up to 35 cm and the reading seems to remain constant even when the water level increases or decreases. For example, when I lowered the water level to 15 cm, the sensor did not register the change and the reading remained at 35 cm.

Similarly, when I increased the water level to 42 cm, the sensor reading did not change.

Can you help me solve this problem?

Hi,  please can you link to a guide that describes how to flash KC868-A16 using idf.py or similar Linux CLI tool ?

I think reading the forum that the source for "firmware 2.1.9" is not available - please advise if I got this wrong.

thanks!

Good Morning , 
I have purchased KC868-A16 and i am trying to use it through Home Assistant.
Unable to turn on Output from Home Assistant.

i used same code in this thred https://www.kincony.com/forum/showthread.php?tid=1628

kindly share me working yaml file

Good evening, I have not purchased the product yet, but I am very interested. I have some doubts about the KC868-A16 model, namely:

How many relay expansions does it support connected to the bus?
How many relay expansions does it support connected via Ethernet cable?

I ask you this because I have to install them in different places in my house.

Thanks in advance.

Hi,

Do you plan to implement MQTT LWT/availability topics in your firmware?

This is actually crucial functionality in IoT for the broker to be informed of disconnections and state changes on reconnection made by other means when the device is offline.

Say you have your board in Home Assistant, you lose connection and then change the state of a relay with a physical switch. On reconnection Home Assistant doesn’t know about the state change and displays the previously set one until the state changes again and appropriate message gets sent to the MQTT broker.

As a bonus, with LWT implemented, your broker knows the availability topic stopped getting messages and displays the device as offline.

I’m pretty surprised this wasn’t implemented from the beginning.

Anyway, thanks for the otherwise nice product. Documentation is somewhat lacking, but I eventually managed to connect my KC868-A8 to Home Assistant with your KCS firmware. Unfortunately, I can’t deploy it in my scenario without LWT.

I refuse to put Tasmota on the board. Tried it and it was flakey, and their support is user hostile. ESPHome is also not an option for me.

Dear Sir/Madam
 Am Nowfal Ibrahim from india, am working at IPCS GLOBAL and we are Leading Automation Trainer in india.
curranty we are planning to start free training for the people who like/work in electrical/home automation  field, i would like to give training with kincony products. so please provide us free sample of products and we can purchase more after getting knowledge about your products

thanks and regards
Nowfal Ibrahim
