We have designed KC868-A32M (ESP32 MOSFET Module) for home automation DIYer. it can easy integrate to home assistant by ESPHome. the hardware have 32CH MOSFET output + 4CH analog input + RS485 + Ethernet + WiFi + Bluetooth + 4G SIM7600 or 2G SIM800L GSM module + DS3231 RTC module + RF433MHz Receiver. We let the the PCB become small size. it will be easy install to power distribution box.
 

Hi

Sorry for the stupid question, 

What is the purpose and way to use (in esphome) the D1 and D2 dry contacts ? 

thank you 

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 ?

Hi...
I am curious about why all of your I/O expander ports are using PCF8574. Why did you choose PCF8574 instead of MCP23XXX series/MCP23017 ? (some more advantages over the pcf8574)
