各位老师，厂家自定义报文如何接入homeassistant

chenxiaowei

我的一个mppt光伏控制器，有rs485接口，我想通过汉枫EW11的dtu设备（支持tcp、udp、mqtt、ali等）将报文传输到homeassistant上并解析，采集PV电压、电流、电瓶电压等数据，因为厂家的不是modbus协议，有什么方法能实现吗？之前通过EW11自动发查询报文，报文自动上传过阿里云，这个与aliyun有没有类似的方式，谢谢

自己用python写脚本，或者用nodered

我尝试用chatgpt写下脚本

这个是是国内的mppt,钰辉，聚源可能都是这样子。带有脚本，协议文件。闲鱼有人卖Nodered的，我见过有人写过脚本，成esphome.

感谢回复，能在这个地方写成教程吗？
我有个朋友在闲鱼买了Nodered方案的，忽略协议文件。万分感谢。
