[arduino code examples for F24]-02 Read digital input ports state

Posted by: admin - 11-28-2024, 11:41 AM - Forum: F24 - No Replies

Code:
/*

 * Made by KinCony IoT: https://www.kincony.com

 *

 * Description:

 * This Arduino program reads the state of two 16-channel PCF8575 I/O expanders

 * and prints the state of all input pins (1-24) to the Serial Monitor. The state of 

 * each pin is represented as a bit in a 24-bit value, where each bit corresponds 

 * to an input pin. The program prints the input state in binary format.

 *

 * Pin Definitions:

 * - SDA: GPIO 8

 * - SCL: GPIO 18

 * - PCF8575 I2C Address: 0x24 for inputs 1-16, 0x26 for inputs 17-24

	Hello, can I configure settings for your presence sensor in esphome: https://www.aliexpress.com/item/1005006030673158.html Or should I configure using remote? Also, which presence sensor component does it use? LD2410? Thank you.

	Hi Admin, I came across your lesson about ''How to decode IR signal by ESPHome'' which i found extremely helpful and straightforward. https://www.kincony.com/forum/showthread.php?tid=1220 I want to know whether it is possible to use an IR receiver like the VS1838B on the KC868-A6 or the KC868-16 and if possible, how to wire it.

Suitable CT clamps for M30

Posted by: sumnerboy - 11-27-2024, 08:33 PM - Forum: KC868-M16 / M1 / MB / M30 - Replies (23)

	Hi, I am very interested in getting an M30 for monitoring the various circuits in my home. Some circuits only draw a 1-2A, some 8-10A, some 20-24A. Can you please provide a list of suitable CT clamps that will work with the M30 for a various range of currents? Ideally model numbers and specifications so we can source them directly if required. Many thanks, Ben

KC868-A4S for heating controll

Posted by: tadam - 11-27-2024, 01:05 PM - Forum: KC868-A4S - Replies (9)

Hello there,

I am looking for confirmation before purchase that I can use this board as I plannig to. Smile
So my plan is to use this board for central heating management. I attached a picture how does the setup looks so far.
I will use Home assistant and esphome.
As you can see I have
- 4 24V AC valve.
- 5 temperature sensor (ds18B20)
- analog pressure sensor (SEN0257)
- leak sensor (just a basic contact sensor)
- opentherm adapter (this one)
- for network connection I will use ethernet

Do I need an additonal power supply (9-24V DC) to power my board? Or it can be power from 5V?

4x 24V AC valve: This is easy, They can go to the 4 relay. I think I will use the normaly closed terminals, in case of a board issue, the heating should not be affected. There is a separate 24V AC power supply, which only responsible for powering these valves.

5 temperature sensor (ds18B20): As far as I know these sensors has uniq id and can use the same pin, with one wire protocol. I can use the 3.3V output and ground from the board, and GPIO01 for the onewire.

analog pressure sensor (SEN0257): This sensor needs 5V can I get 5V out of this board? The output of this sensor is analog, so I can use AI1 for that.

leak sensor: This is just a digital sensor this is trivial too, it can go DI1 and ground.

opentherm adapter: This board need 3.3V, this I can get from the board. But also needs 2 free IO. Is there an IO I can repurpose in this case? There is only one free "bare" gpio left which is this case GPIO2. All other looks like has a special purpose.

I am really excited for this project and looking forward for responses. Thanks in advance.
