dft200-go

Quick and dirty Go CLI for the Sportstech DFT200 standing desk treadmill.

Requires a running bluetoothd and Go 1.11+.

Inspired by https://github.com/machinekoder/deskfit.

Using a treadmill is dangerous. A few notes by a fellow DFT200 owner:

• The Bluetooth feature is unauthenticated. Anyone in range can control your treadmill.

• I haven't figured out the right command for emergency stop, and I found no references while reverse engineering the Android application. Always keep the hardware remote control close to you, especially at higher speeds - pressing the start button twice will trigger an emergency stop.

• Be careful when playing with the Bluetooth interface, you might brick your treadmill. There are commands for reading and (presumably) writing the EEPROM.

• Do not install the Android application - it requests tons of dangerous permissions for no good reason, and at least one variant of it is packed by a APK packer commonly used by malware. The DFT200 manual recommends to install the APK from their website, which is generally a bad idea™.

Setup

Install bluetoothd via your distro package manager and start it:

systemctl enable bluetooth.service
systemctl start bluetooth.service

Find MAC address using bluetoothctl:

scan on
devices
connect <mac>

Alternatively, you can use a bluetoothd GUI like Gnome's native applet, blueberry (GTK) or bluedevil (KDE).

Install to $GOPATH/bin:

go install github.com/leoluk/dft200-go/cmd/dft-cli

Usage

Start treadmill (or continue, if paused):

dft-cli -addr <mac> -start

Pause treadmill:

dft-cli -addr <mac> -pause

Stop treadmill (you don't usually need this, it will stop after you leave it paused for a few minutes):

dft-cli -addr <mac> -stop

Set speed (10-80 for levels 1-8):

dft-cli -addr <mac> -speed <n>

Example i3 config

set $tmMac <mac>

bindsym $mod+Ctrl+1 exec ~/go/bin/dft-cli -addr $tmMac -speed 10
bindsym $mod+Ctrl+2 exec ~/go/bin/dft-cli -addr $tmMac -speed 20
bindsym $mod+Ctrl+3 exec ~/go/bin/dft-cli -addr $tmMac -speed 30
bindsym $mod+Ctrl+4 exec ~/go/bin/dft-cli -addr $tmMac -speed 40
bindsym $mod+Ctrl+5 exec ~/go/bin/dft-cli -addr $tmMac -speed 50
bindsym $mod+Ctrl+6 exec ~/go/bin/dft-cli -addr $tmMac -speed 60
bindsym $mod+Ctrl+7 exec ~/go/bin/dft-cli -addr $tmMac -speed 70
bindsym $mod+Ctrl+8 exec ~/go/bin/dft-cli -addr $tmMac -speed 80
bindsym $mod+Ctrl+BackSpace exec ~/go/bin/dft-cli -addr $tmMac -pause
bindsym $mod+Ctrl+Return exec ~/go/bin/dft-cli -addr $tmMac -start
