Hello,
I recently bought KC868-A16 unit and just installed that in my electric box. I supplied 12V, connected the USB cable and tried to program it with ESPHOME firmware.
The problem I'm facing is that the unit is not showing up as COM port in Windows. Steps I took to enter the programming mode I guess should be:
1. connect USB-C to the computer
2. press and hold S2
3. connect 12V power
This should make the unit switching to upload, shouldn't it?
I tried also alternative path. I connected the unit through ethernet (on WiFi there is no custom KC868-like network so I guess maybe through ethernet it should work). The unit got assigned an IP address (checked it on the router) and can be pinged properly.
When trying to open http://units-ip/ page nothing shows up. I also guess there should be some standard firmware UI accessible under this address, shouldn't it?
How do I proceed? Please support.
