The library does not support esp8266

[15670941101]

Is there any way to use this library directly on esp8266?

I'm not sure. Have you tried it? Does it work? If not, what errors do you get?

[15670941101]

我不知道。你试过吗？它有效吗？如果没有，你会得到什么错误？

Yes, I tried, and the result is 0

It still work, i'm using Wemos D1 Mini and D1 Mini Pro, both works fine. But i can't find correct value with int32

It works for my esp32 lolin32; there is a debug option that gives you the raw RS485 traffic, that should help in debugging.

You need to update your Arduino ESP8266 board package via the Board Manager to get the latest SoftwareSerial driver. Package V3.0.2 works fine with SensorModbusMaster, V2.6.3 does not.
