KC868-A8S GSM ESP32 board released!

Posted by: admin - 06-01-2022, 02:43 AM - Forum: News - No Replies

We have designed KC868-A8S esp32 board, many hardware resource for you to use. it support GSM module for SMS, voice call, GPRS communication. Use SMS or call to turn ON/OFF relay will be very easy for home automation DIY. You can write any code by Arduino IDE to ESP32 wifi/bluetooth/ethernet RS485 module. We will supply demo code for different samples. Everyone can modify and change the code for your own smart home automation system project. it support use by ESPHome for home assistant or tasmota firmware for smart home automation DIY.

Lesson28 - How to send command control RS485 curtain motor

Posted by: admin - 06-01-2022, 02:39 AM - Forum: Home automation training courses - No Replies

This is a demo of curtain motor. this motor support TUYA wifi and RS485 modbus protocol.

Open command

start Motor address function Data address CRC16
Send 55 fe fe 03 01 AD 8A
receive 55 fe fe 03 01 AD 8A

Close command

start Motor address function Data address CRC16
Send 55 fe fe 03 02 ED 8B
receive 55 fe fe 03 02 ED 8B

Set any positon command

start Motor address function Data address value CRC16
Send 55 fe fe 03 04 1E C8 E5
receive 55 Fe fe 03 04 FF* 08 AD

Read current positon command

start Motor address function Data address Data length CRC16
Send 55 fe fe 01 02 01 2B 4D
receive 55 fe fe 01 01 FF* AA 3D

Track range: 0x00—0x64 - 0%--100%
