Monitoring LYWSD03MMC devices in various rooms in my house. Storing room temperature and humidity as well as the device's battery level.
It has been observed that these devices sometime fail to connect even when the battery level is still sufficient. Therefore the app also tries to assess the state of the device based on Bluetooth information (notably connection failures). All collected data is stored locally.
Designed and tested to work on Raspberry Pi (DietPi).
To install run: kimnaty --install.
Use kimnaty --uninstall to uninstall.
The app uses rclone to upload the local database to a private dropbox account for
disaster recovery purposes.
The app uses pylywsdxx which in turn
needs bluepy3. Both are automagically installed during the installation
of the app together with any Bluetooth support needed.
User can set defaults for trending graphs in ~.local/kimnaty.json as follows:
{
"trend": {"hours": 25,
"months": 25,
"days": 14}
}
All entries are case-sensitive(!) and optional. The application will use default values for options that are not present.

As of September 2024 pylywsdxx is distributed under AGPL-3.0-or-later.
