  Ethernet static address
Posted by: MattMueller - 07-16-2026, 01:42 AM - Forum: KC868-A series and Uair Smart Controller - Replies (7)

I use a Board KC868-A16 Rev1.6.3 with tasmota firmware-en-a16.bin from here. After installation I have two ip-addresses (via dhcp) one for wifi and one for ethernet.
In the console I can change the wifi adress to a static address with the command ipaddress1 xxx.xxx.xxx.xxx , that works fine. 
But how can I change the ethernet-address to a static one?

  KCS firmware wishlist
Posted by: D2K - 07-15-2026, 12:31 PM - Forum: "KCS" v2 firmware system - Replies (3)

Good afternoon,
I'm using the KC868-A6v2, KC868-A16v2, and KC868-A16v3 boards on KCS, which completely meets my needs.
I like the functionality and practicality of these boards,
but the firmware is inconvenient:
1. The lack of a backup mechanism and external editing of IFTTT rules when updating the version or moving to another board.
2. The lack of double-tap and hold inputs in the MQTT protocol.
I understand that these implementations can be implemented on esphome, but I would like to see them developed for KCS as well.
Thank you for your product.

  Request for Type A Project
Posted by: kyutimong - 07-14-2026, 04:19 AM - Forum: Apply for free sample product - No Replies

Hello, I'm Mifta from UPN Jakarta in Indonesia. I would love to develop KC868-A4 for my final project in my campus. The project is about control two shuttle from joystick at the same time It would be very helpful if you could share the sample project for me (In this case, I request sample project for Type A). The previous project i only use 3 ESP32 for controlling 2 shuttle and 1 trolly to move synchronously. If you could share the sample project i will give you updates about my project that maybe can be a new application for KC868-A4


You can reach me through my email: miftahul.jannah@upnvj.ac.id
