如何將 SONOFF TX Ultimate 接入 Home Assistant：刷機指南

開始裝潢新家，為了讓智能開關接入 Home Assistant 系統，而展開的刷機之路…

T5 1C 2C 3C 通通有

事前準備

1. USB UART

2. 杜邦線

接線圖

3.3V <---> 3.3V

RXD <---> TX

TXD <---> RX

GND <---> GND

拆解步驟

1. 用一字將底座打開

2. 解開底板螺絲

3. 從旁邊翹開拿下底板 (箭頭方向字一字翹起，或是從左右側翹起)

接上線後，就可以開始刷機了

剛打開時，會是進入 Cycle Mode (燈的顏色一直循環) ，這時候要短路 Boot 與 GND 進入刷機模式 (燈的顏色停止循環)

name_add_mac_suffix 是因為我有大量的 TX Ultimate 需要處理

經緯度是因為有日照時間，可以進入 Night Mode
