  4-20mA Scale for IFTTT is not Precise
Posted by: job-systems - 11-08-2023, 01:12 AM - Forum: KC868-A4 - Replies (3)

Hi everyone, I am new to Kincony products, and have liked them very much until now. 

I have 12x KC868-A4 boards and 24x Dwyer DM-200 Differential Pressure Transmitters connected to the A4 boards on the A1 and A2 inputs that are 4-20mA. (Please refer to enclosed file: Dwyer DM-200).

The DM-200 Transmitter has a range (measured and confirmed) of 4mA = 0 Pascal (Pa) and 20mA = 62.21 Pa (Please refer to enclosed file: Instrument Scale), therefore, I assumed that Custom Value 1 is 0 Pa and Custom Value 2 is 62.21 Pa (Please refer to enclosed file: 4-20mA Scale).

When we go to "Monitor" icon to see what values Kincony is reading live at around 37 Pa on Dwyer, Kincony is showing 35 Pa, and at 0 Pa on Dwyer, Kincony is showing around 8 Pa. The 4-20mA signal is clearly arriving to Kincony, we checked the values of the signal and we get 4mA and around 12 to 14 mA when values of 30 and up Pascal. 

Thinking we where doing something wrong, we put: Custom Value 1 to "-15.56" Pa and Custom Value 2 to 62.21 Pa, like Instrument Scale picture, and values were also not coincident. 

We think there is a problem with scaling inside the KCS_KC868_A4_V2.1.9 firmware. 

Can you check? And let me know?

Thank you.

  Multiple I2C PORTs.
Posted by: djconcept - 11-07-2023, 08:51 PM - Forum: KinCony Server-Mini / Server-16 Raspberry Pi4 relay module - Replies (2)

Hello, I would like to understand the logic, on the board, I find 3 I2C ports:

I2C-0
I2C-1
I2C-10

When i make this: 

Code:
ls /dev/*i2c*

I receive this
Code:
/dev/i2c-1  /dev/i2c-20  /dev/i2c-21

what exactly is the link?

Thank you in advance for your support.

Posted by: jeremy80 - 11-05-2023, 04:20 PM - Forum: "KCS" firmware system - Replies (3)

Hello,

I am trying to send pushover notification from KCS firmware input pin change.

In protocol custom we can make HTTP post but what to fill in field Message and URL so it work with pushover API that is documented below

https://pushover.net/api

Does anyone had already a similar integration to send notification on input change ?
