Need help choosing modules for 32-channel lighting control with Home Assistant

[Karlis_LV]

Hello everyone,
I'm new to KinCony and Home Assistant. I would really appreciate your help.
I want to control my house lighting using Home Assistant, and I need to manage 32+ channels. I’m looking for a solution with the best price/performance.
Important:

• I am not a programmer, so I need a system that works without writing code, just ready firmware like ESPHome or KinCony’s firmware.
  
• I really like KinCony devices, but unfortunately I can't find compact and complete information in one place that explains how to set up a simple lighting project using a few modules.
  
• I prefer using I/O extenders (relay modules) that come in a solid metal case or at least with mechanical protection, not open PCB boards.
  

Could you please help me with:

1. Which modules do I need to build a 32+ channel Home Assistant lighting control system?
   
2. Is there a video or full guide that shows everything: connection, flashing (if needed), and control via Home Assistant?
   
3. Can this setup work without programming knowledge?
   
4. What is the best I/O expander module with relays that includes a metal or protected enclosure?
   
5. Can the system run only on Server16 with CM4 + some simple extender relay board?
   

I want to build a clean and reliable lighting automation system with good enclosure protection and Home Assistant support.
Thank you very much for your help!

1. i suggest you use multi A32Pro smart relay controller. multi controllers just connect to your same router, so that all controller can integrate to one home assistant account.
2. video tour about A32Pro:

A32 Pro introduce: https://youtu.be/yqArOKF5vWc
how to config ESPHome support Tuya module for A32 Pro Controller: https://youtu.be/ERo4x-zoUE4
KCSv3 new functions on A32Pro ESP32-S3 Home Automation Controller: https://youtu.be/6nDQ7tW21us

3. sure, if you download by KCS v3 firmware, just install mqtt broker on your home assistant , it's zero code for config, only need set the mqtt broker. here is KCS v3 online guide: https://www.kincony.com/how-to-use-kcsv3...board.html

4. we not suggest use extend relay way by i2c, because it's not a stable way, just use multi controller connect to router by ethernet cable is best way.

5. Server16 mainly use for install home assistant.

Hi again, thanks for the help!

I haven’t bought any modules yet — still planning. One question: the KC868-A32Pro looks powerful, but for simple ON/OFF lighting control, is it overkill?

Is there a cheaper KinCony module (like KC868-H32BS) that only handles relays, has a protected case, works with Home Assistant (MQTT), and doesn’t require coding?

Thanks again!

it's up to you. just A32Pro use by ESP32, support ESPHome and KCS v3, support multi protocol and many software, voice control by alexa and google home speaker. KC868-H32BS can't do that.

I’m still designing my setup and need a final bit of clarity.

Brain (planned): one Server16 running Home Assistant + MQTT.

Its 16 on-board relays will handle the first lighting circuits.

Expansion need: another 16–32 on/off relay outputs (and dry-contact inputs).

My question:

If all the automation logic, voice control, and MQTT broker will live on the future Server 16, can I attach a simple relay board that does nothing more than listen to MQTT commands and switch on/off
I really don’t understand why every relay-expansion board has to be so complex when my main Server 16 already handles all the logic.

This is why, at the start of the topic, I asked for a single video that explains all the KinCony modules, their types, and the overall system architecture. Unfortunately, KinCony’s YouTube channel contains many great videos, but each one focuses on a single module review and doesn’t provide a complete overview of which modules are required for a straightforward home-automation project.

Yes there are, but in the mid- or long-term you would regret it. 

I went with H32B Pro, and I understood too late that the integrated relays are great for up to 7-8 amps, but anything above can fry them. I had several fried relays I had to replace, because of low-quality LED lights (search for "inrush current" for more info on this forum)

Go with boards that have larger and replaceable relays, such as the F16 or F24, or A32. They will handle high currents and will last longer. For 32 lights, the few dozen extra $$$ will not really matter. Learn from my experience

Because we do not recommend using extended IO solution, such as extend by i2c relay or input board. Because this is not a stable way. Each KinCony controller can work independently, which is more reliable and flxible. if any board broken ,others also can work well.
