KC868-H32BS connecting with external relays / switches

Posted by: fernandobandeira - 02-06-2025, 04:24 AM - Forum: KC868-HxB series Smart Controller - Replies (5)

I currently have 2 panels with some 16a Finder (20.21.9.024.4000) 24v dc relays, these relays controls some lights and blinds, the blinds have a sequencing to it (open, pause, close, pause, open) currently they are being toggled by a switch/interruptor.

I've watched some videos from kincony and looks like I could use the kc868-h32bs, I guess my question is if this is the best option, I basically want to make these relays available on alexa, and it feels like I'd connect the existing switches to the inputs from the kc868-h32bs and then the output would go to the finder relay. is there another way of achieving this? My concern is making sure that the board knows when the relay is on/off as it needs to know if the lights are turned on / off to work properly.

the problem though is that connecting the switch to the board directly would leave it without a backup in case the board has any issues, so it wouldnt be possible to control the lights directly in that case, I wanted to have a backup if possible, I'm not sure if theres a way of the board detecting the relay state otherwise

(Im a software engineer, so not too familliar with hardware, any help is appreciated, I wanna make sure I order the right products for the setup)

KC868-A8M reading Ethernet data

Posted by: MWDH - 02-05-2025, 09:27 PM - Forum: KC868-A8M - Replies (10)

Hello Community,

I want to use the KC868-A8M to do the following:

use it as Wifi AP (Which is easy and I have accomplished) to have access with my phone
read data with the KC868-A8M from a web server from another device via Ethernet (Ethernet is connected to another device which creates the web server)
red data via http get requests

Now the question: Am I able to configure all the get requests in the KCS software and use the answers / data in the IFTTT section? This would make it very easy to program logic to the KC868-A8M.
Or do I need to program my own code in the Arduino IDE to create get requests and react accordingly?

If there is a simple solution, I would be very happy to learn about it, since this will be super helpful in one of my projects.

Thank you very much! [Image: smile.png]

A24 Where DAC?

Posted by: skench - 02-05-2025, 08:52 PM - Forum: KinCony A24 - Replies (6)

Good day, admin, please tell me, do you have a video https://www.youtube.com/watch?v=kLUGJtZg1aQ, the description says the following "how to slove A32 Pro/A24 DAC dimmer"

However, I do not see the inscription on the case as for the A32 PRO DA1 and DA2 in the lower right corner of the case is located on the A32 Pro

So does the KinCony A24 https://aliexpress.ru/item/1005006364867...757axPMWYQ
have dimmer control? If so, where are the inscriptions?

Thanks

I have bought a kincony 868A6. The first time, red led power in on and 6 other red leds are blinking and clicking. I have a 12V power. But now only the red led power is on. No blinking and no clicking for the 6 red leds.
Unpossible to use flashtools. The board is recognized whan i put the usb. But nothing other. Is the board out of order? I try to reset it with the button. Nothing.
What can i do? Send to the seller? thanks for your answer

Help with Bioreactor Automation

Posted by: propag8tor - 02-04-2025, 05:42 AM - Forum: DIY Project - Replies (6)

Seeking Advice: Automating a CO₂-Controlled Bioreactor System with Raspberry Pi & KinCony

Hi everyone,
I’m building a temporary immersion bioreactor system for tissue culturing trees for restoration projects. I want to design a scalable, automated system that integrates CO₂ monitoring, solenoid-controlled gas flow, and light automation—with the ability to log data for future AI optimization.

System Overview:

Bioreactors: 10 shelves, each with 10 bioreactors (total of 100).
Aeration:
- Each bioreactor receives CO₂-enriched air from a pump inside a CO₂ incubator (for sterilization and elevated CO₂ levels).
- I plan to monitor CO₂ levels in 1 vessel per shelf (10 total monitored vessels).
- The CO₂ sensor data will control a solenoid valve (normally closed) to regulate CO₂ for the entire shelf.
Lighting:
- I want automated lighting with control based on PPFD (Photosynthetic Photon Flux Density) or intensity.
Data Logging & AI Integration:
- The system should log all data (CO₂ levels, light intensity, etc.) for future AI-driven optimization.

My Approach & Questions:

I plan to use a Raspberry Pi as the main controller.
I’ve come across KinCony products and believe they could provide a solution. Has anyone used KinCony for similar automation projects?
I’d love suggestions for CO₂ sensors, solenoid controllers, and light intensity sensors that integrate well with a Raspberry Pi & KinCony setup.
I want to allow for future expansion, so modularity and scalability are key.

If anyone can offer suggestions or advice it would be extremely appreciated. I attached an image to help understand what it is I am building.
Thanks

Multiple fan wall project advice

Posted by: coroee - 02-02-2025, 04:39 PM - Forum: DIY Project - Replies (2)

Hello all!

We are working on an art project which consists of 8 walls of server brushless fans that are separated from each other. in each wall there are 30 12v 0.2a fans, and 18 24v 0.5 fans.

We would like to create different cycling programs in each wall that are triggered by a message from a main controller (esp32 / RPi)
The walls are separated from each other so we thought that going wireless should be the cleanest way to build it.

We thought to use a Kincony A6 for each wall, that reads the message through esp-now or controlled by esphome or KCS firmware (can it control several boards?).

I'm a pretty technical guy but making first steps into home automation.. so..

1. Does this setup make sense or is there a more elegant solution?
2. I have some arduino coding knowledge but tempted by the GUI offered through the other solutions - which one of them provides just what I need, including manual on/off triggering of all connected boards + program scheduling?
3. Will the relays bear 6 amps 24v each for several seconds, going on and off for half an hour year (5 days a week, 10 hours per day), or should I opt for SSRs?

Many thanks and a lovely week to come!

Roee.
