Hello,

at first i want to point out that i already have some of your boards used in my automation but not for the dimming.

The goal is to be able to dim these lights:
- 1 LED ceiling lamp, which is actually LED panel inside and it can work with 230V, or 24V DC but this lamp needs 100W power supply. It is dimmable with PMW(12/24V DC).
  https://shop.ledco.sk/loxone-svietidla-2...-2700k-65/  - you can check it here
- 4 LED ceiling lamp which are basically the same as the previous one but smaller and hence it needs only 60W power supply.
- 20 LED spot light GU10, 24V DC and needs 5W power supply.
- also a few LED strips will be there but those are irrelevant for now

When i was checking your boards only KC868-AP looked like a match but i was not sure if it can handle what i described. KC868-D16 is no go because it is without ESP32 and i want to be able to ESPHOME to be able to configure momentary switches clicks as i want.

Also i saw that you mentioned that you are developing a new board as ESP32 dimmer.

Can you please help me with this? What could work with the lights which i described?

Thanks in advance

hello engneer 
now i will start my project.Its villa buldig.
I already get the material from aliexpress
so when i try to test first H32bs .when connect tcp server the connection still 4 or 5 minuts  then  loss onnection
can you help me

And tell me how to write a config for the A64 board for the new mqtt ?
