Overview:

Inside and outside weather stats are shown on a 2.0" TFT display by an Adafruit Feather ESP32-S3 microcontroller and are stored on a micro SD drive.
Outside stats and forecast are performed once (in Setup) and then every 60 minutes in Loop. Content extracted from these visits is saved as global variables for offline use.

This minimizes the number of site queries to OpenWeatherMap.org which are limited to 1000/month.
Whenever the PIR detects motion a series of applications will run.

Screen brightness is mediated by LDR and PWM backlight of the display.

In the demo above, you see both STATS and FORECAST on red backgrounds. They indicate that the info has been pulled down from the website and stored in local variables.

You will not see this reoccur until the 60 minute timer has expired.

API calls for the current weather are made to http://api.OpenWeatherMap.org/data/2.5/weather? for the following current data, but many more parameters are available.

All measurements are metric.

- Date & time

- Temperature, humidity, barometric pressure

- Wind

- Wind chill / humidex

- Daily temp maximum, temp minimum

- Sunrise, sunset times

- Current conditions, e.g., mist, cloudy, etc.

API calls for forecasts are made to http://api.openweathermap.org/data/2.5/forecast?...

Displays: 8-pin 2.0" IPS TFT display module or 11-pin Adafruit 2.0" IPS TFT display module #4311 with built-in SD

Arduino Code: Inside-Outside_Feather-ESP32S3_5.ino You will need to sign up for a free API key. You will also need your WiFi network's credentials.

                            These have been blanked out in the Arduino code.

ESP32 Forget:

If your ESP32's cache of WiFi MAC addresses seems corrupt, run this file to hopefully clean it up: ESP32-C3_Super_Mini_Forget_Cache.ino

If your ESP32 misbehaves, remember to press and hold RESET, press and hold BOOT, release RESET and then release BOOT, in that specific order.
