求助，关于esphome接modbus 传感器的配置文件写法

sss190

手上弄了一个modbus-rtu协议的传感器，打算用esphome刷esp-c3-13u接入ha。该设备为单线上有两个设备一个设备的地址为01一个设备的地址为15H
写配置文件时遇到一些问题，协议如下图

配置文件如下

目前碰到的问题是当前配置文件生成固件写入后可以读取地址为15H的设备的数据，但地址为1的设备的数据无法读取。谢谢

01设备的数据无法读取，设备的日志如下：

直接使用modbus转wifi是可以在ha里读取全部数据

zkxa

直接用HA就可以啊。还用esphome转一下做啥

为了一起接入其他的传感器。用wifi网关没有esphome灵活

通过查询esphome的文档解决了问题
- platform: modbus_controller
    modbus_controller_id: nh193_WDSP_modbus_controller
    id: nh193_WDSP_wind_speed
    name: "windspeed"
    address:  16
    #register_count: 2
    unit_of_measurement: "m/s"
    register_type: holding
    value_type: U_WORD
    accuracy_decimals: 1
    filters:
    - multiply: 0.1

问题出在红字部分register_type，功能码03，register_type应该为holding
另外address是说明书提供的地址10H转为10进制的值16

zkxa

还有一个地址呢

问个问题  HA上的modbus address:是十进制，不是十六进制了？

jjcs

文档写的很清楚

这个是esphome的配置文件。不是ha的

我也碰到同样的问题，一个ESP32s读取address: 0xd6 或者address: 0xd7 着两个同一总线上的两个不同地址设备，读取任意一个都没有问题但是读取两个设备ESP直接挂了连接不上API那位大神帮忙看看那里出问题了！
