Hello
I'm very happy to be using your KC868-A6 card,
but I have a question: Is it possible to use the NVRAM memory of the RTC DS1307 to record information?
I can't use it with the RTClib Adafruit library.
Sincerely

Hi, I'm Anthony from PH and currently focused on Hospitality business resort and hostels.

I'm from Philippines and I want to start a business in automation specialty in resort management (Engineering and Maintenance)

Implementations:

1. Resort with 3km beach front

a. Automate water pumps (Done with DIY ESP32 WIFI Based sensors due to the distance) 300m distance each pumps to water tanks. We have 9 water pumps with 4 water tanks
b. Automate all lights within property (timer based) more than 300 lights
c. 5 Kitchen automation for exhaust fans and other temp monitoring
d. 20 Villas automation, I want to automate all switches for lights, AC, curtains, electric fans and main switch if not booked.
e. Power meter
f. water usage

2. Buildings

a. automate room all switches for lights, AC, curtains, electric fans and main switch if not booked.
b. automate lights in common areas
c. Power meter
d. water usage

Please contact me on viber or whatsapp +639620556065

Thank you!

Hi there. I'm really liking your products and i will be starting a large DIY project sometime in the future so i'm creating a list of products to use. One thing i can't find are wall scene switches that would work by connecting them to digital inputs using RJ45 cable. I know you offer some but i'm aiming at something more customizable like: https://buyriteelectric.com/cdn/shop/fil...1705342406
So multiple push buttons (no touch) that could send a signal to digital inputs.
I'm from EU so i feel like my options are limited. I'm also open to suggestions if you know of another way to achieve this.

Thank you!

Hello. Can I use digital input for 24v AC signals? I want to receive signals from google nest thermostat. On the datasheet I see an optocoupler with two diodes. Does it mean that it can be used for alternating current? But it is signed as EL357. In the datasheet for the EL357 I see one diode. And can be used for DC-DC conversion. Can you help me figure it out? Thank you in advance.

Hi

I emailed hificat@163.com and asked the following question.

I am locking for a control board that has the following

ESP32 WiFi which can be connected to Home Assistant

Has 6 relay outputs which can be controlled via Home Assistant

Has 6 inputs who state changes are passed onto Home Assistant

Has 2 inputs which I can connect Wiegand RFID/Keypads so when a code is enter or a tag is read it is passed onto Home Assistant

Do yo have such a board as I am looking for 2 such boards ?

The response I got was 

KC868-A6 suitable for you.  



here is details:  https://www.kincony.com/esp32-6-channel-...68-a6.html

My response was 

Thanks for the info.

but that on has one serial interface on the board or can I use that for one Wiegand keypad and the 9pin D for the other Wiegand keypad as I need to connect 2 to each board 

then I got this response.

see this photo:
https://www.kincony.com/images/KC868-A6/KC868-A6-1_05.jpg

there are IO1 and IO2 use for Wiegand keypad.

Which I understand but I then asked this question

So I connect the first keypad to IO1 & IO2 and connect the second keypad to the serial port outlined in the diagram.

Or can I only connect one keypad ?

The then told the told me to ask my question on here. So here I am

So my main question is how I connect 2 Wiegand Keypads to KC868-A6

Thanks

Hello!
Is it possible to connect two or more DS18B20 temperature sensors with the current KC868-A4 firmware? How can this be done?

Hi,

Would also be interested in new M30 board.

But looking for some details:

- What type of CT clamps are needed?  The M16v2 works with SCT013 with 3.5 mm jack, but what type is needed here ?

- Can you post details about the accuracy and especially if it can do stable readings of low power usage values like only a couple of watts. I would like to measure the real power usage of some electronic devices.

- Does M30 measure active power, so taking into account the power factor / cos phi ?

Regards,

Can install diferent firmware an use same time?

I have H32B which I bought few years ago. I was using it only by "shorting" contacts and everything works, but now I need to add it to HA. I that case I need to update firmware to enable MQTT (I am thinking so). Connecting directly by IP does not work, I hope it will work after update.

Connecting via NET REMOTE IAP works, I connect in 5 seconds after rebooting, ping is successfully returned, but when I choose firmware nothing happens. I have tried different versions of firmware but I am stuck on same result. As I do not know what processor I have, I have tried versions <5.x and >4.4

   

I have a problem. I have KC868-H32B Pro, KC868-AK ESP32 Programmable Keyboard, KC868-HA V2. How to connect them together? In Home Assistant, KC868-H32B Pro works with MQTT normally, but I can't connect KC868-HA V2 additionally.
