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

Hello everyone, I would like to know if there is any way to control 2 more relays, in addition to the 4 that already exist on the board.

Thank you very much in advance.

if you want replace your old distribution box with a smart distribution box. you need tell us these information:

1. power incoming : 1 phase or 3 phase? if 1 phase, AC220v? if 3 phase, AC380V?
2. every output channel voltage: AC220v? every breaker amp, such as 16A? 20A?
3. how many channel of breaker? such as :
  8 channel: 16A
  8 channel: 25A

4. what software you want to use ? such as home assistant? tuya app?
A:home assitant use in local network, work without internet.
B:tuya app use by cloud server, remote control your device by internet.
C: A and B work at the same time.

Hi,
what are the maximum voltage and current that the inputs of the KC868-M16v2 accepts?
I wish to know in order to select the most suitable CT-clamps for my power distribution box.
If this is specified somewhere, I didn't find it. If so, where is the spec sheet that mentions these values?
Thanks in advance

Hello engineer 

I want to ask about  the RS485 switch panel KC868-HA
- must connect power for all wall panels separated or can make one lope as KNX
- When yes one lope. how many can connect in one lope to avoid problems with less power? What is the cable size can enough 
- Also, RS485 cable can also make it one lope?  when yes how many in one lope 
- what type of cable is suitable and also the size 
   

Hi there, 
I am hoping i can easily adapt the alexa seral module by kincony for adapting my PIP inverter into home assistant.
Please can I have the schematics  or other help to help achieve this successfully
