An Activity Watch watcher which monitors whether you have set your height-adjustable table to sitting or standing.
Unfortunately my adjustable table doesn't have an API or anything similar. Therefore I need an external device which measures the height of the table. This external device must have internet access and a distance sensor.
I have used an ESP8266 micro controller. It has in-built Wifi and GPIOs to control sensors. As a distance sensor I have used an HC-SR04 Ultrasonic Sensor, because I had it lying around.
I printed my case using the Prusa I3 MK3. As modeling software I used Fusion360. You can download the 3D model here (Thingiverse).
| Name | Price |
|---|---|
| ESP8266 | 6.50€ |
| HC-SR04 | 5.16€ |
| 3D Printed Case | ~0.25€ |
| Total | 11.91€ |
Definitely affordable.
When the hardware is finished and powered on, it should be possible to get the table height via the curl command:
# curl http://192.168.2.4/measure
{"table_height":128}
virtualenv venv # create virtual environment
venv\Scripts\activate # activate virtual environment
poetry install # install required packages
poetry run aw-watcher-table [--testing] [-v] [--verbose]
pyinstaller --clean aw_windows.spec
pyinstaller --clean aw_linux.spec
- Move the aw-watcher-table folder inside the dist folder into the Activity Watch installation location
- Restart Activity Watch
- Right click the Activity Watch tray icon. Under modules you should see the aw-table-watcher. Check it to start the aw-watcher-table.
- Go to the config directory. You can find the path for your OS here.
- In the aw-qt directory you should find a aw-qt.ini file.
- Add the aw-table-watcher to autostart_modules to enable auto-start. It should look like this:
[aw-qt]
autostart_modules = ["aw-server", "aw-watcher-afk", "aw-watcher-window", "aw-table-watcher"]
[aw-qt-testing]
autostart_modules = ["aw-server", "aw-watcher-afk", "aw-watcher-window", "aw-table-watcher"]
