A24 pro 24v compatible?

Sat, 09 Aug 2025 23:30:21 +0800

Due the lack of 63amp contactors in 12v. It's possible to use a power supply with 24v for the a24pro? Not for the relay.. to the unit itself? Thanks a lot!

A24 + power socket

Sat, 08 Feb 2025 09:40:39 +0800

Good day, I drew the diagram using the site https://app.diagrams.net/

Dear friend, please tell me if I understand the diagram for connecting the power socket pcorrectly?

Is it possible to do without a contactor and use only a machine?

Settup heated floor

Sat, 08 Feb 2025 01:28:05 +0800

Dear friend, can you please make a video on how to set up and connect a thermostat and heated floor on the A24 board, perhaps you have already done something similar before, I think many will be interested in how to do this, thank you

A24 Where DAC?

Thu, 06 Feb 2025 04:52:43 +0800

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

Anybody use DMX on Kincony A24's RS485 on EspHome in Home Assistant?

Wed, 16 Oct 2024 07:29:56 +0800

Good day. Has anybody set up DMX on Kincony A24's RS485 in EspHome in Home Assistant? I tried installing the Github add-in at https://github.com/andyboeh/esphome-dmx512, but I'm a beginner and haven't gotten it to work so far. The Kincony's input and outputs work fine, but I don't know how to proceed. I've put this in the Kincony's Yaml file, and the logger reports the value being sent to DMX_1, but my fixture's DMX indicator doesn't come on, so I don't even know if I wired it correctly. Anyway, here are the Yaml settings:

uart:
id: uart_bus
tx_pin:
number: 33
allow_other_uses: true # For ESPHome >= 2023.12.0
baud_rate: 250000
stop_bits: 2

dmx512:
id: dmx
uart_id: uart_bus
tx_pin:
number: 33
allow_other_uses: true # For ESPHome >= 2023.12.0
uart_num: 1
periodic_update: true
update_interval: 500

output:
- platform: dmx512
channel: 1
universe: dmx
id: dmx_1

light:
- platform: monochromatic
name: "Test Lights"
output: dmx_7
id: light_test

A24 Display options

Is there any possibility to connect a display to the A24 panel? I do not use the gsm connection, nor the K-thermometers.
