Using OBD for dashboard display?

Does anyone have experience linking an OBD plug (bluetooth or hardwired) to a dashboard display (either resembling gauges or as a 'head up' display)? It seems a simple way of having live information on things like oil and water temperature; volts and amps. If fault code deciphering were included that would be a bonus, but not our main interest. I assume plugged-ins (as opposed to bluetooth to phone) are USB powered, and that an auto-cut-off is essential so that it it does not drain the battery. All and any insights and intelligence welcome!

I use dash command app and a blue tooth obd, but do not leave plugged in when not using as the 12v supply to the obd is a permanent supply.

Perhaps this past topic will be of interest

Interestingly on my van a water cooled bay. If it's plugged in before starting the van the immobilizer is permanently activated until the odb device is removed. I assume this is an anti theft protection.

Does not happen on mine i can leave it plugged in but the power red light on front of obd on all time

I'm going to follow this, as I'm interested in getting more info from the engine - the dashboard on Juniper is very lacking in information!
