Templogger

Logging and plotting of temperature

Python module for logging temperature and humidity from Xiaomi Humidity and Temperature sensors to an SQLite databise while continuously plotting the data using a Dash server. Works perfectly on a Raspberry Pi.

Components

The module consist of two submodules:

1. logger module, containing:
   • A HTDevicePoller class for sampling the HT devices
   • A HTDataBaseHandler class for accessing the SQLite database
2. A visualiser module containing the HTDataVisualiser class for hosting a local Dash server for visualising the logged data.

The HTDevicePoller creates a thread per HT device for connecting and reading out samples of humidity and temperature with the given interval. When a sample is obtained, it is written to HTDataBaseHandler, which handles serialising access to the database. HTDataVisualiser starts the Dash-server, which with a given interval updates a plot with the historic samples. In the templogger_main.py, an example of how to setup instances of the modules are given, using the contained devices.config-file that can be read with the config-parser provided in utils.
