Created a temperature sensor system that can generate alerts whenever temperature or humidity goes above or below a limit configured by the admin portal. Along with Elasticsearch and Kibana graphs can be generated and also data can be seen on top of the floor plan to understand hot and cold spots in a building.

The repository below contains code and instructions on how to setup the Raspberry Pi device to report temperature/humidity data along with manual alerts to the server: https://github.com/ankurp/thermostat-sensor

The server code where data is received and saved, notifications are sent, and the entire system configured via the admin portal is here: https://github.com/ankurp/thermostat
