# Wemos D1 mini and Wemos32 mini shield
-   Installation of file: Copy and replace file in wled00 directory
-   For BME280 sensor use usermod_bme280.cpp. Copy to wled00 and rename to usermod.cpp
-   Added third choice of controller Heltec WiFi-Kit-8. Totally DIY but with OLED display.

### Platformio requirements

For Dallas sensor uncomment `U8g2@~2.27.3`,`DallasTemperature@~3.8.0`,`OneWire@~2.3.5 under` `[common]` section in `platformio.ini`:
```ini
# platformio.ini
...
[platformio]
...
; default_envs = esp07
default_envs = d1_mini
...
[common]
...
lib_deps_external =
  ...
  #For use SSD1306 OLED display uncomment following
  U8g2@~2.27.3
  #For Dallas sensor uncomment following 2 lines
  DallasTemperature@~3.8.0
  OneWire@~2.3.5
...
```

For BME280 sensor uncomment `U8g2@~2.27.3`,`BME280@~3.0.0 under` `[common]` section in `platformio.ini`:
```ini
# platformio.ini
...
[platformio]
...
; default_envs = esp07
default_envs = d1_mini
...
[common]
...
lib_deps_external =
  ...
  #For use SSD1306 OLED display uncomment following
  U8g2@~2.27.3
  #For BME280 sensor uncomment following
  BME280@~3.0.0
