(Disclosure: I work for Microsoft, but this project is in no way sponsored or endorsed by the company.)\n\nFeature planning \u0026 roadmaps will be maintained in this repo's Issues.\n\n# Requirements\n\n* Firmware: [CircuitPython v8.x for ESP32-S3 TFT PSRAM](https://circuitpython.org/board/adafruit_feather_esp32s3_tft/) (currently in alpha)\n* Python Libraries:\n    * [Adafruit CircuitPython library bundle for v8.x](https://circuitpython.org/libraries) (currently in alpha)\n    * [Adafruit_CircuitPython_AzureIoT library](https://docs.circuitpython.org/projects/azureiot/en/latest/)\n\n# Software Configuration\n\nConfigure the device's behavior by modifying the variables under the `# Configuration` comment immediately following the `import` statements.\n\n|Variable|Description|\n|--------|-----------|\n|delay|The amount of time to wait between sensor readings, in seconds|\n|temp_warning_c|The minimum temperature, in Celcius, at which a warning status will be triggered. Values less than this number will be considered OK. When the temperature is in a warning status, both the Celcius and Fahrenheit will be displayed in yellow.|\n|temp_critical_c|The minimum temperature, in Celcius, which should be considered critical. When the temperature is in a critical status, both the Celcius and Fahrenheit will be displayed in red.|\n|humid_warning|The minimum relative humidity at which a warning status will be triggered. Values less than this number will be considered OK. When the humidity is in a warning status, the relative humidity will be displayed in yellow.|\n|humid_critical|The minimum relative humidity which should be considered critical. When the humidity is in a critical status, the relative humidity will be displayed in red.|\n\n# Secret Configuration\n\nWifi connection code uses CircuitPython's `secrets.py` convention, as shown in [this project](https://learn.adafruit.com/mqtt-in-circuitpython/circuitpython-wifi-usage). To avoid accidentally saving credentials in GitHub, I've added the file to `.gitignore`.\n\nCreate your own `secrets.py` file in the root of the file system. It needs to contain a dictionary with the SSID. Copy the code below into your new file and populate it with the correct values for your environment.\n\n\u003e **Note:** If you want to use the device in offline-only mode, create the `secrets.py` file with an empty dictionary or comment out the line that sets `ssid`.\n\n```python\nsecrets = {\n    'ssid' : 'your-ssid-here',\n    'password' : 'your-password-here'\n}\n```\n\n# Status LED\n\nThe onboard NeoPixel is used as an indicator of overall status.\n\n|Color|Indication|\n|-----|----------|\n|Red|One or both sensor values are in a Critical status.|\n|Yellow|One or both sensor values are in a Warning status|\n|Green|All sensor values are OK|\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbwyatt%2Ffeather-th-azure-iot","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbwyatt%2Ffeather-th-azure-iot","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbwyatt%2Ffeather-th-azure-iot/lists"}
