Hello. This board is exactly what i need... but....
is there a way to really isolate optocoupers input ? 
if same as (very good) 868-a16, the input are powered by same power supply as all the board.
then if someone put voltage (not contact) at input, it will burn all board.
is it possible to cut/separate/disconnect 12V and GND for optocoupers input ? (then use external power supply for this) ?
on a16, no jumper for this, but all 12V on opto in are on a single track. than you can Cut to isolate (and use own gnd)
is it also possible on 868-ai ? it depend of the routing (one track or different tracks, ...)
thanks for you help and you fantastics cards.

dear Admin,

using M30 on 240 VAC I get Power factor values outside the range (0-100), for example 190 or 3000

I use the ARM firmware: M30_V10_241107Res249Unsign.bin
here's the config:
    platform: modbus_controller
    modbus_controller_id: modbus_hub_m30
    address: 1166
    register_type: holding
    name: pf1
    id: m30_1_pf
    accuracy_decimals: 1
    value_type: U_DWORD_R
    filters:
      - multiply: 0.000011921

Hello!

I have a Kincony A6 V 1.4Sp motherboard.
I collect pulses from water meters on the Digital input and process them with domoticz.
These operate with reed sensors and there is noise in them.

Can I count on firmware that handles de-bounce? I would need a value of 1000ms.

Is there any input on the device in ESPeasy where a pulse counter can be recognized via GPIO?

Thank you!

Hello,
I am planning to use about 15 KC868-HA-V21 modules behind 6-gang momentary switches throughout my whole house and connect them to the KC868-AP dimmer board. The LED strips I am using are 24V.
Can I also use this 24V supply to power the KC868-HA-V21 modules? The documentation states that it is supported, but I want to make sure it is a safe and reliable choice. Or, would it be better to use a separate 12V power supply for the modules?
Thank you for your advice!

Hello,
is possible to use DM4 with ESPHome and Tuya ? B8M works fine, but DM4 has some trouble in tuya_wifi_mcu_light_output.cpp

Here is the log:

Hello,

I am planning a project based on the KC868-A16 v3.1 (REV:1.6) board. My peripheral types include 5V digital sensors (TTL/CMOS) and low-power 5V loads.

Could you please help me with the following technical questions:

1. LO0 and LO1 with 5V: The official documentation specifies 12V/24V for the LO0 and LO1 power supply. Is it safe and functionally possible to apply a 5V external voltage to these specific channels instead?
   
2. Onboard 5V VCC Usage for LO0 and LO1: Can I use the internal 5V VCC rail from the board to power the LO0 and LO1 loads? The total load current will be under 1A, which is within the XL1509-5 regulator capacity. Are there any internal limitations preventing this?
   
3. 16 Digital Inputs with 5V logic: How can I modify all 16 Digital Inputs (INPUT1 and INPUT2) to safely and accurately read active 5V digital signals (TTL/CMOS)? What is the exact hardware modification procedure for the PCB?
