Our project requires the following functionality:

Home Assistant should be able to modify fountain schedules (pump and lighting operating times).
The schedules must be stored inside the KC868 controller.
If Home Assistant, MQTT broker, network, or Internet connection fails, the controller must continue operating autonomously according to the last received schedule.

We have already successfully tested:

MQTT integration with Home Assistant
Scene Mode
Custom Protocol (UDP)
Local IFTTT rules
Local Timer rules

Our questions are:

Is there any official API (HTTP, MQTT, TCP, UDP, Custom Protocol, etc.) that allows remote creation, modification, enabling/disabling, or updating of Timer rules from Home Assistant or another external system?
Is it possible to remotely modify Time-based IFTTT rules and save those changes permanently in controller memory?
Is there any documented method to upload a schedule configuration to the controller programmatically?
If this is not supported by KCS v3, what is the recommended KinCony solution for a system where schedules must remain operational after Home Assistant, MQTT, network, or Internet failure?

Another question:
We can't find a way to create a schedule that works as a time range.
For example:

The pump turns ON at 09:00
The pump turns OFF at 23:00

The light turns ON at 18:00
The light turns OFF at 23:00

If KCS has a built-in feature that allows us to create, modify, and activate such schedules programmatically, it would solve most of our requirements.
Another question:
In IFTTT, we can only create a rule such as:

If time is 09:00 → turn pump ON

However, if communication with Home Assistant is lost at 09:05, the 09:00 event has already passed and the rule will not run again.
For example:

Pump schedule: 09:00 ON, 23:00 OFF
Home Assistant fails at 09:05
The controller switches to autonomous mode

Home Assistant should be able to modify fountain schedules (pump and lighting operating times).
The schedules must be stored inside the KC868 controller.

For example:

Pump schedule: 09:00 ON, 23:00 OFF
Home Assistant fails at 09:05
The controller switches to autonomous mode

In this situation, the pump will not turn ON because the 09:00 event was missed.
Could you please explain the recommended way to implement autonomous operating schedules in KCS v3 when Home Assistant may become unavailable, but the controller must continue operating correctly according to its schedule?
We are trying to avoid developing custom firmware and would like to use standard KCS v3 functionality if possible.
Thank you very much for your support.]]> <![CDATA[Wiegand]]> https://www.kincony.com/forum/showthread.php?tid=9479 Sat, 13 Jun 2026 02:48:35 +0800 williemcvillage]]> https://www.kincony.com/forum/showthread.php?tid=9479

I try to integrate 2 Kincony boards ( KC868-A16 an KC868-AP) in Homeassistant by mqtt broker Mosquitto.

For the board kc868-A16 I made the correct settings I think.

Mqtt : enable
broker address : mqtt://192.168.0.157
broker port : 1883
broker username : mqtt
broker password : 123

In the screen ' monitor' : status mqtt : connected.

My problem is the integration in homeassistant. I followed your tutorial, but at step 3, I don't understand how you imported the yaml files of your boards in the file editor.
Is it possible to explain how to import the yaml files for the boards KC868-A16 and KC868-AP ?

Second question : When I connect the secondboard ( KC868-AP), can I use the same settings for the mqtt broker ?

I see many people asking for configuration.yaml for A16, A6..etc.

Every person is spending time, building their own yaml-file.

Could you just provide a complete template for each board (A16, A6), that combines all switches, binary_sensors, ADCs, DACs, Temperature sensors... in one text block, combines as one device (with yaml anchor) ready to copy into Home Assistant configuration.yaml?

I think it would make the boards more attractive, if there is an easier start for integration.

Does anyone want to share their configuration.yaml?

I’m struggling with a Kincony KC868-A16 board (ESP32-based) integrated with ESPHome in Home Assistant. I can see all the entities (switches and binary sensors) in my HA dashboard, but none of the physical relays or digital inputs are responding.
The Hardware:

Board: Kincony KC868-A16 (V1.5 or similar with 4x PCF8574 IO Expanders).
Power: Externally powered with a stable 12V 2A DC supply.
Checked with Multimeter: PCF8574 chips are correctly powered at 3.3V.

The Problem: When I toggle a switch in Home Assistant, the UI icon turns "ON" for a split second and then immediately reverts to "OFF". This suggests an I2C communication timeout or write failure. No physical "click" is heard from the relays, and LEDs don't light up.
ESPHome Logs: The I2C scan successfully finds all 4 chips at the expected addresses:

Code:
Found device at address 0x21
(Inputs)
Code:
Found device at address 0x22
(Inputs)
Code:
Found device at address 0x24
(Outputs/Relays)
Code:
Found device at address 0x25
(Outputs/Relays)

Log output:

Code:
[C][pcf8574:024]: PCF8574: Is PCF8575: NO, Address: 0x24

However, when I trigger a relay, nothing happens physically.

here some .yaml config examples for my digital sensors and outputs:
