Goodnight,

I'm having trouble using the codes to use the PCF8574 of the KC868 A8, using the same code for input and output, I noticed that it already comes with the standard Digital Input 1 > Turn on > Digital Output 1, does anyone have this code so I can work above him?

Thank you very much in advance

Please help me choose the materials required for the building consisting of two floors


first floor
1- Lighting circuits 51
2- ventilation circuits 4
3- Air conditioner circuit 10
4- The number of motion sensors is 10

second floor
1- Lighting circuits 54
2- The number of curtains is 14 with 28 circles
3 - ventilation circuits 3
4 - Air conditioner circuit 10
5- Heater circuits 3
6- The number of motion sensors is 10

I will use HOMEASSISTANT and want use Switch contains a feedback lamp

What happened to the Amazon online store? Everything says unavailable.

Hello, this year i was finished installation of my new boiler room with 3 boilers, 16 pumps, 16 electric valves, one pellet burner... Now i need to make automation of all components. I was test some process with sonoff TH16 and 4CH pro devices and home assistant, only to see what exactly need and can to controll, and the main problem is that i need a lot of temperature sensors, pressure sensors, ultrasonic sensors, relays, contactors etc.

The best solution is to use home assistant, but if you have some suggestions, i am open

In text bellow i will try to explain what i plan to do, and it would be great that you suggest me components for my automation

1. Measure temperature from -25 to 100 C on 42 places, and to have a possibility to controll devices (relays) by that temperature
   
2. Measure water pressure in whole heating system on 10-12 places, and to controll electric valves for water and air accordingly measured pressure
   
3. Measure water level in vertical expansion tank of 1200 lit, and controll electric valves for water.
   
4. Measure level of pellet in pellet tank of 1800 kg (2000 mm height)
   
5. Connect one smoke and fire sensor to controll fan in case of smoke
   
6. Relay output on/off or no/nc for control pumps, burner, electric actuators, lights. Relay for pumps, burner, electric actuators will be controled by measured temperature. All relay outputs will controll electric contactor with 24vac coils.
   

How can I add ZigBee gateway to the homeassant ? please

How can I learn the IR remote for air conditioners of an unknown brand to use the Homassetant
Can you make a video tutorial ? please

I think I might have already asked this, but will the H32BS OR the kc868-server work with KC868-A16?

Hello Kincony,

I really enjoy both my KC868-A4 and KC868-A8 units. They work very well! I currently use Tasmota which I find excellent (10.0.0.3 for A8 and 12.2.1 for A4).

I have started to do more intensive use of the A4 board and I went to connect the second TEMP connection shown on circuit to find it was not connected. I can see why it was changed - to add 3V3 which is important however I do not have an up to date circuit diagram.

The circuit diagram I have for A4 is: https://www.kincony.com/download/KC868-A4-schematic.pdf

I would like an updated drawing if possible.

Thank you in advance

Adam

I have now home  i want used  will use home assistant

thank you

I have 2 sensor and the output for communication is RS485. Kincony only have 1 RS485. Can Kincony support 2 sensor at same RS485?
