Tuya MQTT protocol provides various turnkey protocol specifications to help you quickly implement the required features, including device models, sending and receiving data to and from the cloud, topology, OTA update, timer, remote configuration, file transfer, and Network Time Protocol (NTP). Stay tuned for more features.

Standard functions lower the bar for IoT project development, improve efficiency, and reduce the lead time.

This topic describes the publish topics and subscribe topics.

Publish topics

An IoT device can publish messages to the following topics for sending data or requests to the Tuya IoT Development Platform.

Feature	Message type	Topic
Get the model	The device requests the definition of the device model.	tylink/${deviceId}/thing/model/get
Report property values	The device positively reports its properties.	tylink/${deviceId}/thing/property/report
Send property values	The device responds to the property setting.	tylink/${deviceId}/thing/property/set_response
Report property values in bulk	The device reports its property updates or those of the sub-devices in bulk.	tylink/${deviceId}/thing/data/batch_report
Report events	The device reports event-triggered messages.	tylink/${deviceId}/thing/event/trigger
Perform actions	The device returns the result of the operation.	tylink/${deviceId}/thing/action/execute_response
Get online and offline	The gateway reports the online status of its connected sub-devices.	tylink/${deviceId}/device/sub/login
Get online and offline	The gateway reports the offline status of its connected sub-devices.	tylink/${deviceId}/device/sub/logout
Bind sub-devices	The gateway requests activating the discovered sub-device and establishing a topological relationship.	tylink/${deviceId}/device/sub/bind
Establish topological relationship	The gateway adds the device topology.	tylink/${deviceId}/device/topo/add
Delete topological relationship	The gateway deletes the device topology.	tylink/${deviceId}/device/topo/delete
Query topological relationship	The gateway queries the topological relationship from the cloud.	tylink/${deviceId}/device/topo/get
Update firmware via OTA	The device reports the firmware version information.	tylink/${deviceId}/ota/firmware/report
Update firmware via OTA	The device requests information about silent updates.	tylink/${deviceId}/ota/get
Update firmware via OTA	The device reports the status and progress of the update.	tylink/${deviceId}/ota/progress/report
Network time protocol (NTP) service	The device requests to sync time with the NTP server.	tylink/${deviceId}/ext/time/request
Daylight saving time (DST) service	The device requests the DST service.	tylink/${deviceId}/ext/time/request
Upload files	The device requests the presigned URL to upload a file.	tylink/${deviceId}/ext/file/upload/request
Download files	The device requests the URL to download a file.	tylink/${deviceId}/ext/file/download/request
Send the configuration file remotely	A device gets the latest configuration file.	tylink/${deviceId}/ext/config/get
Report custom format data	The device sends custom format data to the cloud.	tylink/${deviceId}/channel/raw/up
