Get Temperature & Relative Humidity ++

Created to get data for a thermostat app, mostly for learning and experimenting. Runs a for-ever loop and outputs json file, temperature celcius and relative humidity. Feel free to comment :)

TODO:

• Handle 203 - Deprecated: Add warning (currently dies)
• Handle 429 - Throttling: Limit traffic / request frequency (currently dies)
• Randomize interval? (Expires header + for loop already adds some time variation)
• Reduce timeout (currently transport default)
• Remove json file in/out or make optional
• Status lookup if errors
• Storage: bson, mongo ? time series db ? graphana (historical data available..)
• Compare RH at different temperatures (for other proj)
• Sometimes gives 304, even with Expires check. Is Expires not always precise?
