Description

BS440 listens for information from a Medisana BS410/BS430/BS440/BS444 or compatible bluetooth scale. When received, it passes the information to all found data processors found in the plugin folder.

Preferences

Before using this app, copy BS440.example.ini to BS440.ini and personalize your settings. This file contains the general parameters for communicating with the scale, and which plugins to use.

Automatically start

Copy the right files from the dist/init directory.

For generic linux with SystemD support:

cp dist/init/linux-systemd/bs440.service /etc/systemd/system/
systemctl daemon-reload   # tell SystemD to detect new service files
systemctl start bs440     # start the service now
systemctl enable bs440    # start the service at boot
journalctl -l -f -u bs440 # show + tail the logs of bs440

Attention: the systemd service file assumes you copied the contents of this repo to /opt/BS440

Plugins

Currenly these plugins are available:

BS440mail: Mail the last 3 stored sets of data to the user
BS440csv: Store results locally in csv and graph results through webserver
BS440domoticz: Store data in virtual sensors of Domoticz home control system
BS440google: Store data to Google Fit account
BS440runalizel: Store data to local Runalyze database
BS440mqtt: Send collected data via MQTT to Home Assistant for excample
BS440influxdb: Store collected data into InfluxDB time series database for easy graphing using Grafana

Plugins are found in the plugin folder and named BS440pluginname.py. Each plugin uses its private .ini file named BS440pluginname.ini To enable a plugin, add it to the plugins key in BS440.ini.

Directions on how to install prerequisites, configure and use a specific plugin is found in the Wiki

BS440mail

Maintainer: Keptenkurk

Last 3 results are mailed to the user mail adress as configured in BS440mail.ini

BS440csv

Maintainer: DjZU

Data is added to a local CSV file. Data is presented by running plotBS440.py which starts a webserver and serves graphs to the user. You can use any web server to serve a static site based on the csv files. You can find a working example using the Caddy webserver in dist/caddy/.

BS440mqtt

Maintainer: jinnerbichler

Send collected data via MQTT (e.g. to Home Assistant)

BS440influxdb

Maintainer: qistoph

Store collected data in InlfuxDB (e.g. for Grafana)

Domoticz

Maintainer: Tristan79 - Status: Testing

Configure the Domoticz and user details in BS440domoticz.ini. When data is received, the sensors will be automatically generated. That easy!

The optional option hardware_name is the name of the dummy hardware to you can use, if you leave it empty or commented it out, it uses Medisana as default.

After a first run BS440domoticz.ini is updated. In which you can override the ids to use (if necessary). Note that the weight sensors are identified by ID and Unit while the other sensors are identified by idx in BS440domoticz.ini.

BS440google

maintainer: managementboy / Keptenkurk

BS440google updates weight and fat parameters in Google fit (http://fit.google.com) For creating an account and authentication file please see the Wiki for this repository.(https://github.com/keptenkurk/BS440/wiki/How-to-use-Google-Fit)

BS440runalizel

maintainer: jovandeginste This plugin stores data to local Runalyze database. Runalyze is a performance analyzer for atlethes which goes far beyond the performance trackers like runkeeper and runtastic.
