+# Pv router Version 1.3 for ESP32 or TTGO T display 
+
+## TTGO version 
+<img src="./images/routeur.jpg" align="up" height="300"  >
+I created this pv router to separate the power part of the analysis part. 
+After 2 years of working with an ESP8266, I made evolutions to upgrade to an ESP32. ( and visual Studio Code )
+first time I use Oled display and I migrate to a TTGO tdisplay, for an easyer intregration. 
+
+this router use a very simple tech by using phase differences.
+The project can reproduce easily for the electronic board.
+however I made an industrial version of it to make things easier.
+<a href="https://www.helloasso.com/associations/apper/formulaires/4">The board was sold by a French Association ( APPER ) </a>
+
+You only need to by separatly :
+ . A <a href="https://amzn.to/3hVCLpf">TTGO-Tdisplay</a>
+ . A <a href="https://amzn.to/3CtCHqi">SCT-013-30</a>
+ . And an 12V - AC power supply ( Sinus ) you can made it with a modified old 12DC coil transformer. ( see below )
+
+For packaging, I use the box that comes with the TTGO.
+
+# Prerequiement : 
+A circuit board has been created and is available ( tips )

+
+# Installation : 
+## configure Wifi 
+rename the file wifi.json.ori to wifi.json and change SID 
+## upload
+if you know your configuration you can change it on config.json
+
+Upload the firmware and filesystem. the system will start and working
+
+## OTA UPload 
+You can use OTA upload by the web page /update 
+Build firmware of filesystem with VS and upload the .bin
+
+

+## ESP32 Version or DIY version
+connections : 
+** ESP32  ** 
+OLED  : 
+3.3V 
+GND 
+21 SCL
+22 SDA 
+
+SCT013 
+div bridge R/R  between  3.3V and GND
+SCT013  connected at the middle of div bridge and pin 34 ( --> Linky )
+condensator 470uf between GND and the middle of div bridge. ( filter )
+***********
+
+** TTGO ** 
+pin 32 GRID
+pin 33 SCT013
+******** 
+
+The carrier is made with a 12v transformer power supply.
+The bridge rectifier is removed and the wavy part is kept
+There is a divider bridge not to exceed 3.3V and a diode for half alternation.
+
+The assembly as a whole will raise the power and the direction of the current.
+Like the ESP8266 version, it can connect directly to the Wifi dimmer to control the power.

+
+# preparing power: 
+Open the transformer and remove the diode bridge

+
+Close the transformer and verify the voltage. ~12V AC ( 9-16v ) and adjust the divider bridge if needed ( output 3.3V max )
