I get this message when compiling the code. On boards i chose ESP32 Dev Module Documents\Arduino\libraries\WebServer_WT32_ETH01\src/WebServer_WT32_ETH01.h:33:4: error: #error This code is designed to run on ESP32 platform! Please check your Tools->Board setting. 33 | #error This code is designed to run on ESP32 platform! Please check your Tools->Board setting.

Hello, Is it possible to connect with you for a project.

[@YaserAliHusen]

yes, just send me an email

Hi it’s good.....but can u help Schneider conzerv em 6436H energy meter readings taken on node red and I m using PUSR-N520 device converter.....RS485 to Ethernet converter....

Thank you for your comment. Sorry I dont have the device, so I cant try it🙏

Maybe you must copy or install library: ArduinoRS485

[@joachimpaternini3835]

Hello, i get a fault when compiling the project. 'SERIAL_PORT_HARDWARE' was not declared. Can you help please?

[@YaserAliHusen]

Did you install the libraries?

[@joachimpaternini3835]

@@YaserAliHusen yes. I installed ArduinoModbus, ArduinoRS485 and webserver wt32 library

[@JT-os1lf]

Thanks for the tutorial! Do you know, could this also be set up as a client? Or is the ESP32 only available as a Modbus server in the arduino IDE?

[@YaserAliHusen]

Yes you can setup as client, You can check on example code of library

Sorry sir, I want to ask approximately how far the maximum range of relay control via smartphone is?

[@YaserAliHusen]

while on the same network

[@putrihidayahilra6648]

@@YaserAliHusen To configure the network, do you just use the Arduino Ide and Web Node Red applications or do you need additional applications?

[@YaserAliHusen]

@@putrihidayahilra6648, I use Arduino IDE to configure Board IP Address, and from board connect to network using ethernet cable, make sure the IP address is same with local IP configuration

[@alebassi2000]

It's giving library errors, please help me

[@YaserAliHusen]

Did you install libraries same with the video? Do you use device WT32-ETH01?

[@YaserAliHusen]

In Libraries folder, there must be ArduinoRS485 folder inside

[@alebassi2000]

@@YaserAliHusen Yes, the ArduinoModbus and ArduinoRS485 libraries are installed in the libraries folder, however they appear as incompatible with the w32-Eth01 board. I am using the W32-eth01 board. What version of the libraries and installation of the esp32 boards are you using?

[@YaserAliHusen]

@@alebassi2000, version same with video 1.0.9

[@alebassi2000]

@@YaserAliHusen It's the same version of the Arduínomodbus library, but it still doesn't work, can you see the version of the esp32 boards installed on your computer?

Error showing while uploading even though all libraries are fine

[@YaserAliHusen]

Try to unplug all pin when uploading, plug only related pin for uploading

[@shaikhshoaib9189]

Sir please make a course on node red

[@YaserAliHusen]

My videos are indirect courses actually, you can follow the steps. For basic node-red you can find out in youtube or udemy or forum
