Getting fed up with the feeling that the temperature around here is ever changing, I created this little sketch to log the temperature and humidity to my InfluxDB server. Using a Grafana instance to display the data.
Having a Wemos D1 and a AM2301 roaming around the bench, this was used to create this data logger.
For an excelent guide to get InfluxDB up and running on your server, see https://docs.influxdata.com/influxdb/v1.3/introduction/installation/.
Note: I am running InfluxDB behind a reverse proxy, you will need to adjust the port number in the sketch.
Likewise for Grafana there is a excellent setup guide: http://docs.grafana.org/installation/
Afterwards upload the grafana-dashboad.json file to get your temperature dashboard started.
Enter your WiFi, InfluxDB and DHT sensor type/pin as constants in the sketch, upload and you should be ready to go!
