1.0.4

Beta

Part of the code is optimized to avoid the loss of NVM3 in some special cases, which will lead to the failure of pairing

The thread transmit power is optimized.

When the factory Settings are restored successfully, the led bar will blink 3x red for reminder

1.0.2

Beta

Switch cluster :add "Initial Press" (0x01), "Short Release" (0x03), and "MultiPressOngoing" (0x05) events report

When the device is removed by all gateways, it will automatically restore the factory Settings (ps: apple home is invalid, because when the device joins the apple home, it will join two thread networks, and only one will be removed when it is removed).

Level Cluster :fixed incorrect on-Level minimum
