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 either 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 built-in Wi-Fi and GPIOs to control sensors. As a distance sensor I have used an HC-SR04 Ultrasonic Sensor, because I already had it on hand.

I printed my case using the Prusa I3 MK3. As modeling software I used Fusion360. You can download the 3D model here (Thingiverse).

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}

1. Go to the config directory. Find the path for your OS here.
2. In the aw-qt directory find the aw-qt.ini file.
3. 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-watcher-table"]

[aw-qt-testing]
autostart_modules = ["aw-server", "aw-watcher-afk", "aw-watcher-window", "aw-watcher-table"]

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 pyinstaller.spec

1. Move the aw-watcher-table folder to the Activity Watch installation folder
2. Restart Activity Watch
3. Right click the Activity Watch tray icon. Under Modules find the aw-table-watcher. Check it to start the aw-watcher-table.
