    The objective of the project is to create a device using a microcontroller (Arduino) with a NFC device capable of communicating with a 1st Android Phone. The microcontroller with the NFC device will send a message to the 1st Android Phone and will receive a message from the 1st Android Phone. The microcontroller with the NFC will then send the 2 stored messages to a 2nd Android Phone. The sending and receiving of the messages will be done through the NFC device to be connected to the Microcontroller and the NFC devices of the Mobile Phones. The preferred NFC device to be connected to the Microcontroller is the PN532 and the preferred Microcontroller is the Mega.

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
