网络继电器--Modbus

Jaing

剛好最近在研究 HA -> 485
提供 Progs Pont 寫的流程 https://www.youtube.com/watch?v=hw3m3GAoCeM
Modbus RTU to Home Assistant with TTL to RS485 electronic card and ESP01 Relay (Soft and Hard)

簡要內容, 準備 ESP01_單Relay , TTL->RS485 轉換板.... 連接 TTL -> ESP01
ESPHOME 建立 MODBUS by 8266
儲存下面code 並安裝
(logger:
  baud_rate: 0
及MODBUS 固定IP位址)
