Repurposing Trimble LiveSign Pro Panel

Hello
I’ve got a Trimble LiveSign Pro panel which I believe runs Android. I’m not sure what version yet.

I would like to use one to run the HASS UI and use it as a control panel for my installation.

Is anyone familiar with these and whether they are locked down etc? I haven’t been able to login to mine as I don’t know the default password.

Thanks in advance
