    ESP8266 to Control Tuya Zigbee Gateway 6 μέρες left
    ΕΠΙΒΕΒΑΙΩΜΕΝΟ

    I connected a Tuya Zigbee Smart Switch with a Tuya Zigbee(3.0) Wireless Gateway through Smart Life App, and it works perfectly with the app (ON/OFF). I need someone to help me to control the same Tuya Smart Switch with my ESP8266 through the Tuya Zigbee Gateway, without using the Smart Life App. (ESP8266 and Tuya Zigbee Gateway are connected to the same wifi network, so there is no need for internet) So the command should go from my ESP8266, to the router, to Tuya Zigbee gateway to the Smart switch, as shown in the attachment. If you do not have the Tuya hardware, you can connect to my Computer using Anydesk to download to my esp8266, then we can check it if it works with Tuya

    You must live in the Western Balkans, Eastern Europe, or in Latin America. I'm looking for a high school student or a university student to help me build an Internet of things (IoT) device using MicroPython on the ESP32. (ESP32 is a microcontroller just like Arduino). You do *not* need to currently possess an ESP32. Why don't you need any experience? I would rather work with someone who is inexperienced yet very intelligent, rather than someone who is experienced yet not very intelligent. You need to be able to work five days each week for one hour each day. You may choose the five days that are convenient for you. You may work at any hour of the day (or night) that you prefer.
