Friends,

I've saved the original content from my FM25Q16 flash.
You can find it here.

Yep, I've read your program and everything seems to be understandable. You've made a fantastic work!! I'll share my software on github, I've already forked yours. I've checked the power supply of the system and it's not isolated. So this idea to add an ESP32 with SD Card is a bad idea because ground ...

I'm looking to fit an ESP32 instead of this ESP8266 in order to store those datas and host a small web page. For the moment I just need a stand alone energy meter. In the future, I will mix everything together with a node-red server in order to adjust water heating and car charging according to ...

Inside the metal case of the wifi module, there is a ESP8266EX and a FM25Q16 16Mb serial Flash Memory. Why so much flash inside??
Could we store historic datas in this flash?

I think YES!

What do you think about this?

EDIT :
I made a mistake it's a 16Mbits so only 2Mbytes... :/

I'll try to backup the ESP8266 with Esptool https://github.com/espressif/esptool
And spy the RS232 transmission between MCU and ESP.

In order to make a webpage displaying historic and actual power value.

This is the content of my 24G04




G80F924 has a JTAG connection available. Some pins seems to be shared with the LCD.

Bad news...
I've got DataMan, SuperPro and LabTool but none of them is able to read the content of the G80F924...
Does someone has a good idea?

OK so the main MCU is especially made for energy measurement. It's based on a 8051 µC. I've got some programmers like superpro, labtool... I'll try to read it and 24G04. https://i.ibb.co/XttFP4h/IMG-4656.jpg https://i.ibb.co/Y87kYDh/IMG-4657.jpg https://i.ibb.co/YL3Kmrc/IMG-4658.jpg https://i.ibb.co/ ...

Hi guys, I've opened it. Behind LCD there is a G80F924 I think that everything is made here... You can find a chinese datasheet here: http://www.dycmcu.com/data/upload/201506/111111471.pdf Close to it you can find a Soic 8 marked with 4G04. Regarding the wiring it looks like and I2C EEPROM. BR24G04 ...

I don't remember exactly what the manual tells but it's the same way to connect this wifi module than ITEAD SONOFF modules. And they are running with an ESP8266 too.

Toulon7559. 1) If switched on AND PRESS LONG ON WIFI BUTTON, the device is a Wifi Access Point 2) you make contact with that Access Point by means of your Smartphone (or comparable) and tell to which destination-LAN it should go by giving Wifi Identification&Password 3) after completion of the ...

Hello Guys, I've bought the same smart meter with wifi connection. I've opened it and YES it's works on ESP8266. I'm not able to find the source files and I, first, had the project to add an ESP32 to the RS485 ModBus in order to retrieve datas. For me, Wisen software works great but no power history ...
