I have tried to get the ETH working on my KC868-A8S. I have tried the following:
Binary that shipped with the board - ETH not working.
LAN8720_UDP.ino using static address 192.168.1.200 - debug says connected but it does NOT appear on LAN
KC868-A8S_Digital_input_Web_Server-ETH.ino -using DHCP settings - returns IP address 0.0.0.0 and the following:

Arduino IDE can't seem to find it.

Is there a quick how to for this board with Arduino? I just need to write the sensor data to MQTT.

Hello,
Is there a way to use the KC868-A16 Board to directly control an LED using PWM or are all mosfets only controllable using the PCF8574 I/O Expander? 
Thank you!

I order a number of I2C connectors intending to use them on the 868-A6 board but none of them are the correct size. Can anyone provide the specifications for the female connectors or refer me to a site/s that has the specific connectors, please? I would appreciate a specific part or part number. 

Thanks

Hello everyone ! especially Hifikat!  We recently connected a long-range antenna to the LoRa - SX1278 module, this cable passed near the RTC module of the KC868-A6 module, on occasions when we put the backup battery in the RTC Socket, our finger when making contact with the battery and being near the crystal, we have noticed that the RTC readings are beginning to fail, so we thought about placing a metal casing to protect this part of the circuit, we also thought about grounding the negative of the module to ground, is it okay to do this? What other recommendations could you give us for this situation? In advance thank you very much for your attention !

Dear Community,

I would like to confirm something please.

Do I need an additional Kincony / ESP enabled server if I have 10 x K868 E16S on the same via ESP Home / Home Assistant local network?

6 x K868 E16S in ground floor DB and 4 x K868 E16S in 2nd floor DB using local LAN to each device.

No wifi switches or devices, all hard wired.  

Note: replacement for circa 2007 VIPA 200 PLC system in a large residential home.

I may also need a separate AI and DO 24v on each floor.

Regards,

Keith

improvement:
   
1. support use Tuya app for remote control OUTPUT and monitor INPUT state.
2. support TCP Server, TCP Client, UDP, MQTT, Tuya different protocol at the same time by ethernet.
such as you can use Home assistant (by mqtt) in local LAN network and Tuya app for remote monitor by internet.
3. add "MQTT send all" option. if "enabled" , MQTT state message will feedback all channel's information. if "disabled" , MQTT state message will feedback single channel's information.
4. support control by KC868-AK keyboard.

how to order tuya licence:

here is Tuya licence for "H32BS,H32B,COLB" firmware , it can let your board remote control by internet.

1:telll us your email, we will send the licence to your email

2:tell us your area(choose from :China/Westen US/Eastern US/Central Europe/Western Europe/India)

IMPORTANT: check for your tuya account, which REGION you have registered.

Check in your tuya or smart life mobile phone app: Me -- Settings -- Account and Security -- Region

according to the "Region" visit here (https://developer.tuya.com/en/docs/iot/o...i0ku9l07qb) to check your server location.

           

if you really don't know how to check, just send us your tuya or smart life app account name, we will check for you.


3:tell us you model(choose from Kincony A4/A6/A8/A8S/A16/A32/A64/A128/E16S/AI/AK/H32BS/H32B/COLB)

4: The license has no time limit, and the tuya platform provides corresponding services and guarantees

5:Once sold, it cannot be returned or refund

6:One licence only for one product


Tuya internet cloud server locate in 6 positon in the world:
Location-A: China
Location-B: Western US
Location-C: Eastern US
Location-D: Central Europe
Location-E: Western Europe
Location-F: India

please tell us which server location your app account used. such as if your account is "Western Europe" ,tell us "Location-E: Western Europe".

if you want to order, please contact with us, you can pay by PayPal or Bank account.

I have connected up a dimmable led light bulb with a solid state relay from analogue 1 on the A4Sbut i seem to be getting the following problems.

1: when the relays are off from the color LED-1 in Home assistant the bulb is still on but very dim. when i switch it on it goes full brightness but when i switch off the bulb does not go out it goes back to very dim.
2: i set up a automation to use a momentry input switch to increase brightness and another input to dicrease brightness, again the bulb is still on when off but now i have to keep pressing the button several times to increase brightness instead of just holding the button. I also notice that the bulb starts to flicker at certain increases. can you explain whats going wrong please.
3: i have attached the photos to make sure it is all wired correctly.

I am using this template {"NAME":"KC868-A4","GPIO":[32,0,227,0,224,225,0,0,0,1312,1,226,0,0,480,1152,0,1120,1056,1088,0,1,1,1,0,0,0,0,4706,4707,4704,4705],"FLAG":0,"BASE":1} ("https://blakadder.com/kincony-KC868-A4/").
 I am using everything except the 4 analogs; instead, I would like to use the digital inputs to connect 4 float switches ("https://www.amazon.es/-/pt/dp/B089VTDG7P/ref=asc_df_B089VTDG7P/?tag=ptgogshpadde-21&linkCode=df0&hvadid=634424762838&hvpos=&hvnetw=g&hvrand=12299730209074816985&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=20876&hvtargid=pla-943952460943&th=1").
