KCS v3 - Remote modification of Timer/IFTTT rules from Home Assistant

[vsadnik11]

Hello KinCony Team,
We are using a KC868-A16 controller with KCS v3 firmware and Home Assistant integration.
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:

1. 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?
   
2. Is it possible to remotely modify Time-based IFTTT rules and save those changes permanently in controller memory?
   
3. Is there any documented method to upload a schedule configuration to the controller programmatically?
   
4. 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
  

or

• 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
  

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.
