Stop Vive Controller auto turn-off

Hi guys,

I'm working on a mixed reality application and therefore am using 3 vive controllers - one of which is strapped to a stand motionless. As there is no movement, the controller turns off frequently which can disrupt the process.

Is there a way to override this and keep the SteamVR controllers on permanently until forced off (holding the application button for 5 seconds).

Thank you
