When you can get data from ESP in Node-RED, you can record data into database from node-red after getting data. You can use postgresql or MSSQL database or another, you can vie lirbary in manage pallet@@Jihenguesmi
I was continuously sending data to the Node-RED dashboard in real-time without any reset. You can enhance this by recording the data into a database like PostgreSQL and visualize it on the dashboard based on specific time intervals.
Thank you for the sharing, I have some question about the code. #ifdef ESP8266 #include #else #include #endif #include How do I find those files? (, & ) Or I should include which library?
@@YaserAliHusen Thank you for the information! May I know can I try this with esp32? I just tried it and it can run using Arduino, but cannot run in node red. Is that anything I need to change inside node red? (I had changed the IP address). Or I need to create the TCP server as previous video?
@@yinyenlee109, for ESP32, maybe you can use ESP32. You must check connection between ESP and computer (node-red) you can ping the ESP to check connection. Then in node-red flow, check the IP of ESP as modbus TCP server
@@indrapurnama8659, apakah sudah download file ESP dan node-rednya? ESP dan node-red berkomunikasi menggunakan modbus TCP, jadi pastikan ESP dan node-red dalam jaringan yang sama
@@indrapurnama8659 Apakah sudah mencoba kode dari saya? Pada ESP kita setting modbus TCP Kemudian Node-Red membaca nilai pada modbus di ESP. Silahkan dilihat juga video saya yg lain terkait modbus
Thank you for sharing your knowledge. Is it possible to reset the energy counter?
Yes you can
Or you can record into database
how exactly can i record into database

Thank for your really good video. But how can you reset the data ?

hello i hope u answer me as soon possible , i ve got too many unknown node in ur js project u provided , how to solve this
I use only node-red-contrib-modbus,
The others node is default node.
My flow was not complicated, you can compare in the video

How do I find those files? (, & ) Or I should include which library?
For modbus, you can download from the github and paste into library folder.

@@YaserAliHusen how about the ESP8266wifi.h and wifi.h?
@@yinyenlee109, You can find it in Libary, usually if you choose board ESP8266, will automatically add this library

Maaf pak apakah ada tutorial untuk menghubungkan node rednya perstepnya
bila ada tolong pak
terimakasih
Apakah sudah download filenya?
Seingat saya, saya sudah share juga flow node-rednya, jadi tinggal import saja file jsonnya.
@@YaserAliHusen saya kebingungan untuk menghubungkan esp dengan rednote
Apakah ada tutorial untuk menghubungkan esp dengan rednote seperti video itu
@@indrapurnama8659, apakah sudah download file ESP dan node-rednya?
ESP dan node-red berkomunikasi menggunakan modbus TCP, jadi pastikan ESP dan node-red dalam jaringan yang sama
@@YaserAliHusen apakah itu menggunakan modbus terlebih dahulu agar bisa tersambung pada ip node red?
@@indrapurnama8659 Apakah sudah mencoba kode dari saya?
Pada ESP kita setting modbus TCP
Kemudian Node-Red membaca nilai pada modbus di ESP.
