 ## How to use
 
-1. Change your credentials in `wifisetup.h`.
-1. (Optional) In `smartMeterLogger-esp32.ino` uncomment `#define SH1106_OLED` if you compile for sh1106 instead of ssd1306 and set the i2c pins (and address) for your oled screen.<br>If you do not use a oled you can leave this setting as it is.
-3. Save all files and flash the sketch to your esp32.
-4. Connect your esp32 to the smart meter.<br>Take note that to read from the smartmeter the `DATA` signal has to be [inverted and level shifted](#level-shifter--inverter).
-5. Switch on the esp32. If you added a ssd1306/sh1106 oled screen, the ip address (or an error) will be visible on the screen.<br>If there is no oled you can check the ip address on the serial port in the Arduino IDE.
-6. Browse to the ip address of your esp32 to see your current energy use.

 ### ESP32: LilyGo TTGO T7 with external antenna
 
-SmartMeterLogger is developed on LilyGo TTGO T7 boards. The LilyGo TTGO T7 has an external antenna connector and a decent 3.3v LDO.<br>Without an external antenna the WiFi signal tends to be too poor to be of any use over longer distances and/or through several walls. The board will have to modified slightly to enable the external antenna.

 Below you can see how to enable the external antenna. Move the zero ohm resistor from position 1-2 to position 3-4. Or remove the resistor and solder position 3-4 closed.
+<br>Another nice thing with an external antenna is that the current needed to operate the logger drops below 250mA so the logger can be powered by the smartmeter.
