[Arduino demo source code for KC868-A4]-15 internet control by ESP Rainmaker

[Ali Hamza]

this is a simple demo source code for KC868-A4 remote control relay by ESP RainMaker.


1. install arduino IDE with "Additional Boards Manager URLs": https://raw.githubusercontent.com/espres...index.json
2. Arduino IDE "Board" chose: ESP32 DEV Module
3. Arduino IDE "Tools" -- "Partition Scheme" -- chose: "RainMaker"
4. Download code
5. Scan QRcode to add device.

In the YouTube you show the procedure.. But I'm not sure about the board. That's the board is connected to wifi or what?

by wifi.

[Ali Hamza]

If the board can connect it self to wifi.This means it can be used from outside the house... Like IOT projects?

[admin]

sure

This error is coming... While compiling.?
What to do.

sorry, i don't know the details, we not suggest to use Rainmaker, Tuya solution is better.

[Ali Hamza]

So can  we connect GVA to tuya , or can tuya aap work like a iot like rainmaker ?

sorry, i don't know the details, we not suggest to use Rainmaker, Tuya solution is better.

suggest you use our KCS v2 firmware, maybe all functions for your needs is enough.

Hi everyone, 
When i give 12v, 2amp pawer supply the all Relay turn  (normally open) close but only one relay remain open... Why
And also please confirme me when there is no firmware and i give 12v  to board will all relay turn on?

yes, you need download firmware firstly. now no firmware in ESP32.
