- the next alarm.

Enable:
- step counter
- double click
- tilt
- display of step counter
The stepcounter value is published to gadgetbridge automatically if bluetooth is enabled. The frequency of publication is driven by gadgetbridge. Initially, it is on a 30 minutes frequency. When the realtime tab of gadgetbridge is selected, the frequency is set to every 5 seconds. If the watch lost contact with gadgetbridge for more than 30 minutes, the stepcounter is also refreshed when bluetooth is reconnected.
The bluetooth notification work with gadgetbridge very well. But keep in mind, bluetooth in standby reduces the battery runtime.

This application let you download community based watch faces. Browse watch face with left/right button. Clic on the icon when you find yours.
Here you can find an overview of all watchfaces on github.
Note that the information are downloaded in real time (remember to activate WiFi):
- The list of watchfaces.
- The preview of each watch.
A long press in the middle centers the map to the current gps position.
In connection with OsmAnd the watch can also be used for navigation. Please use the osmand app, otherwise a lot of messages will be displayed.
gps tracker that generates .gpx files. Only works properly with watches that have GPS. A long press on the crosshairs starts and stops the logging. The .gpx files can be downloaded via FTP and imported directly into e.g. GoogleMaps or OSM. The trash icon deletes all files to save space.
Get realtime data from a powermeter over mqtt.
The activity tracker let you check your activity.
In the settings, set your step length and your goals in step and meters.
When associated to Gadgetbrige, activity is reported regularly. If you need to ensure a synchronization, for example at the beginning of an activity or at the end, you can use the refresh button. It will force a synchronization.
The trash can button allows to reset step counter. Useful when starting a new activity an keeping exact track of it.

A simple calculator. Beware that the button C/CE has two functions. A short touch uses CE, which clears only the recent input. A longer touch uses C, which clears all inputs and basically resets the calculator.
A remote for controlling Kodi. Includes a player tile and a tile for a remote control.
A simple MQTT player. I personally used it to control the Phoniebox of our little one, if needed. Phoniebox brings a small extension to expose attributes and commands into MQTT. But I implemented it configurable, so that it can be used with other players exposed through MQTT.
A configurable MQTT Control board. You can add labels that show formatted values, buttons that just publish something or switches that basically subscribe to and publish an on/off state. In my case, I can switch on/off my printer, see some battery values of different devices and make a random noise on a buzzer in a specific project.

A simple Pong game using the Accelerometer of the T-Watch 2020. It also has some nostalgic sound.
An app to view the state and progress of my 3D Printer. Uses G-Codes over WiFi to communicate.
A Bluetooth mouse using the Accelerometer of the T-Watch 2020, that you can connect to your PC or even your android device. Getting it to connect can be hard on some devices, but should work fine on most.
A very specific app for my needs, as I have two ESP32 powered Weatherstations and wanted to show some raw values of them. Might not be the prettiest app, but it does its job.

Press the button for 2 seconds, after that an quickmenu appears. Here you can select the tiny camera icon to take a screenshot. This can be downloaded via the built-in FTP server (binary and passive mode, username: TTWatch and password: passord), if activated. The file name is screen.png.
Or the other way:
The firmware has an integrated webserver. Over this a screenshot can be triggered. The image store as png and can be read with gimp. From bash it look like this
wget x.x.x.x/shot ; wget x.x.x.x/screen.pngPro-tipp:
lgrossard! made a little Python script to generate and download the screenshots from the t-watch here.
You can change background in the display settings.
If you want to use your own background image, simply upload a PNG with a resolution of 240x240 pixels via ftp to the Watch and name it bg.png and set it in the display settings page 2.
