Hello. I'm configuring the KC868-A8 board with Esphome and the Tuya license. However, I found some errors and would like to share them for a possible solution. KC868-A8 board esphome + Tuya
It's giving an error that I don't know exactly. error image attached.

Hello,

I have purchased the KC868-ATC V1.4 and want to use the rs232 functionality to control a Heat recovery system.
I use the tuya app to control my house, however i am not sure how to convert this app and KC868-ATC to the full protocol functionallity in the pdf...

Anyone any ideas?

I have a tuya developer account and Arduino IDE, i have created a IDE code, but doesn't work, the connection to tuya is missing i think...

2. KinCony cloud service function:
remote control or monitor sensor state by browser (mobile phone / Windows PC / Apple MAC computer)

3. price of KinCony cloud server:

5usd/year for one board
free 2 years only for KinCony official online shop customer. (shop.kincony.com)

if you buy products from KinCony offical shop. You can send email (web@kincony.com) to us, tell us your "order number" and "order photo" , "board model" and "serial number" or "UID". We will add your board serial number to our cloud server.

how to use KinCony cloud server:

a. login by KinCony cloud server webpage: https://mq.kincony.com/qq/login
b. register user name and password
c. login with your user name and password
d. add your device by SCAN QRcode or INPUT your serial number.

how to generate your QRcode by yourself:
use this STRING https://mq.kincony.com/qq/device/qrcode?did=xxxxx  xxxxx replace
for example your board's serial number is: d3671a7ba2618996a7b56b3c
so you can paste this URL to your web browser: https://mq.kincony.com/qq/device/qrcode?...96a7b56b3c
Then it will create the QRcode photo, you can download, maybe you can print a label, stick on your board.

e. Now you can remote control your board.

I just received the keyboard and i am trying to read button state with modbus. I try to use this: https://www.kincony.com/forum/attachment.php?aid=2240
but it is really unclear to me.

I try coils, inputs reg, and holding with:
1 stop bit, no parity, 9600 baud.

I have 3 others devices that work well on the same modbus line ( with different MB address ).

Can you help me with the correct way to poll button status ? (i will do a request every 1sec).

thank you in advance.

Can anyone tell me if the KC868-AIO supports more than two temp sensors?

From the videos it looks like it has two GPIO ports for temp sensors, but not sure if that means only can use two?
Or can multiple temp sensors be hooked to each port ?

We have a project that needs 4 temp sensors. Would we have to use analog temp sensors if we needed more than 2?

Thanks!

Hello we have a project that will have 25 mag locks.
When you provide 24v the mag lock will engage.
These will lock and unlock wine cabinets.

Each mag lock has two outputs. A door sensor and a mag sensor.
These outputs are dry closes contact.

We will be running 6 conductor wire to each mag lock.

So basically we need 25 relays, and 50 dry contact inputs.

We want to use "home assistant". so the board needs to integrate well with it.

Would the KC868-AIO be the best board for this?

Bonus question - I see I can add temp sensors. Can I only add two? We need 4 total.

Thanks!

i would like to suggest a module like https://shop.kincony.com/products/rs485-...e-by-sht30
It should be modbus, becouse 1wire couses problems for longer distances
For european clients, we use 60mm round flush-mounted box and that product cant fit  there.
Mabye you can just did some KC868-HAv2 additional functionality?

Hi,

Is this possible to control GPIOS between two boards?
I have A32M and A64 and i want to do something like: input1(Board A) -> output1(Board B)
I want to use esphome (i need it for the project) and i dont want to use HA.
Can i do that?


P.S. 
Great work with your boards !

v3.0.1 improvement:

1. fixed bug with ethernet STATIC IP mode.
2. support KinCony NEW Cloud server, remote control and monitor A32 Pro Controller by mobile phone and computer (PC & MAC) via internet by web browser.
3. support "auto discovery" for home assistant by MQTT with zero code config.
4. support Apple HomeKit directly to use.
