After bttn has performed an action, it shows the result with green (OK) or red (FAIL) LED ring. To change the duration of the result light, do the following:
1. Sign in at http://my.bt.tn
2. Find the bttn you wish to adjust and click "Properties" next to it.
3. Under advanced properties, you can see "Result light indicator" field. Click red "Edit" bttn to change the value.
4. Pick a new value for "RESULT INDICATOR LIGHT DELAY" from drop-down menu and click "save". All done!
Please note that after the green or red result LEDs turn off, there may be a 0,5...1 second delay because before bttn can launch another action, depending on network conditions. If your next press right after the green/red result does nothing, please just try pressing again.
