We have designed KC868-AP. It is a ESP32 16 channel PWM dimmer board. It use PCA9685. The PCA9685 component represents a PCA9685 12-bit PWM driver. It uses I²C Bus for communication. every channel output have MAX 3A driver chip. KC868-AP support use by ESPHome in home assistant. It also have digital input and relay output.

Hi!

I'm in the process of researching to build a house and have a centralised place to control lights, blinds, etc.

Needs & Goals

1. Have ESPHome Ethernet boards with relays I can control using regular light switches (momentary switches too) or through home assistants automation. This could be used for lights, blind motors, etc. Won’t need more than 16A per relay
   
2. Have ESPHome Ethernet boards with PWM dimming capability for 24V analog LEDs with 3/4A Per channel. I created 1 channel mosfet board as a proof of concept dimmer with LEDC component from ESPHome and it works okay.
   

1. As I understand relay boards will work with switches, but Would relay boards work also with temporary switches / push button?
   
2. Are these board 0 delay when activating the relays? My main goal is to have an immediate response from the moment the switch or the command is triggered to when the relay turns on. I have seen some videos where a lot of relays are turned on at the same time and they seem slow.
   
3. Is there any video of relay and dimmer board using ESPHome to see the speed? What’s the max Amp per mosfet channel?
   
4. I’m honestly VERY lost on the product line. I have seen KC868-A8 could be a good fit (at least to do an initial test). A 16 relay version doesn’t seem to exist?. KC868-E16S seems another interesting one but it goes really high on price so I will need to be 100% sure about speed
   
5. I’m still in research phase but I’m assuming a house will need at least 32 relays, and might or might not be all boards in the same placement. So I’m thinking it might not be a good idea to pick one big board but maybe several smaller ones?
   
6. What products do you guys would recommend?
   

You can use this network tool update KC868-H32B Pro controller by ethernet cable.

Welcome everyone

Please advise me what is the appropriate system for car parking in the basement
What are the proposed devices for the system, and what are the ideas of automation that are suitable for car parking in the basement, for example, motion sensors to control lighting, and what are the other proposed sensors, controllers, and .............

I hope that you will provide me with all the suitable ideas and proposed devices for the implementation of the parking lots in the basement floor

Hi

I have a situation when Home Assistant starts all my entities from 2 COLB modules have 'unknown' values. That's because the COLB modules are note sending periodic state messages ore they have no availability topic.   They are sending data only on state changes. That's could be critical in some situations like climate control. 
Example:
Turning on or off the heating in some rooms based on windows states. If a window in a room is closed then turn on the heating in that specific room. Now When HA starts the state of the window will be unknown so the heating won't start. That's only a banal example but in some critical scenes this could be an issue.
Proposed solution:
Make COLB to periodically (ex: every second) send stats data or when HA starts make some request to COLB topic to provide current sensor states.

This could massive improve the device reliability. Is it possible? Thank you.

Hi Team

In Lesson 3 - of Home Automation Power distribution Box - below is the link

New tab (kincony.com)

Kindly confirm the What is the "Amps " used for ( 12V DC contactor) in Hardware lists ?



Thanks & Regards,

KC828-Server has two ethernet
I installed Debian on CM4 with ipV4 192.168.1.128
another ipV4 is 192.168.1.129, work mode MQTT

My problem is KC828-Server can be pinged from 192.168.1.128 to 192.168.1.129, but unable to respond mqtt command, neither to login until I do a restart then everything works fine.
This happens many times in a day, and I can't figure out how to solve it other than restarting the module.
Please advise.
