This script does the following using a Raspberry Pi:
- Retrieves temperature, humidity and pressure data from a BME280 sensor.
- Retrieves Honeywell thermostat information from Honeywell's online portal.
- Runs two relays which turn on the humidifier when humidity is too low and also turns on the furnace fan at the same time.
- All of this is uploaded to Thingspeak and to a local Mysql server.
