Zigbee Subdevice Error Code

Last Updated on：2024-02-18 06:46:22

Tuya Zigbee sub-devices will record abnormal behaviors and report the recorded anomalies to the gateway after networking and during regular network timing.

The following table lists the supported error codes:

Error code ID	Description
0-15	Original hardware built-in Reset sources1: Unknown error2: FIB reboot3: Upgrade reboot4: External IO abnormal reboot5: Low voltage reboot6: Watchdog reboot7: Software initiated reboot8: Software Crash reboot9: Flash abnormal reboot10: Irrecoverable hardware abnormal reboot11: Hardware internal CPU access error12: Power-off reboot
16	Reboot: Sub-device abnormal reboot
17	Disconnection: Sub-device lost connection with the parent node
18	Active disconnection: Sub-device business layer logic triggered the device to disconnect itself
19	Passive disconnection: Sub-device disconnected after receiving a remote disconnection command
20	IO exception: Device IO remains in a latched state for an extended period (e.g., button continuously pressed)
21	Memory leak: Memory not released causing insufficient SDK resources, etc.
22	Short address change
23	Received ZCL_RESET_TO_FACTORY_DEFAULTS_COMMAND_ID command
24	Received gateway F0 command
25	Wake-up time too long (low power device wake-up monitoring)
26	Received gateway's abnormal factory reset command
27	Device self-recovery failure
28	Device group upgrade failure

Error codes are in string format, with every 5 bytes representing one error code data. The first 4 bytes are a little-endian timestamp starting from 2000.1.1 00:00:00, and the last byte is the event ID.

Adding 946656000 to this timestamp gives the UTC time, which means the above error code event indicates a remote disconnection event occurred at 2023.12.12 14:33:13.

When the sub-device has not successfully synchronized the time, the timestamp carried by the error code data is all zeros.
