Does anyone use OBD Gauge for monitoring RPM and water temperature?

I use a ScanGauge. It works well, and uses very little sleep power when the car is off.

Water temperature is a number I usually have on the display. RPM isn't. I had it displayed for a while out of curiosity when I first got the ScanGauge, but it's just not that interesting in a Prius; the engine is always being managed by the car, it does what it does, and after that initial curiosity, the urge to hover and second-guess it sort of fades.

 

On my 2026 LE, I use the OBD Fusion or Car Scanner app, both of which display on the infotainment screen via CarPlay.

 

P10 for years monitoring engine temp and aux battery. Has user set alarm limits.

 

Interesting! Does a 2026 LE have an engine oil temperature sensor, then?

I wonder why it would be that much cooler than the coolant.

 

I use a V-gate vLinker FS Bluetooth OBD2 Scanner with the Torque Pro and AATorque app on Android Auto.
This allows you to display lots of parameters on the central display with Android Auto including, RPM, coolant temp, oil temp, Volts, SOC, speed, LTFT1, AFR, MAF, timing Adv, etc...
There are hundreds of parameters displayable on up to 10 panels with dial or digital display.
I wouldn't do without it anymore, since I use it continuously.

 

I've been in iPhone world for a relatively short time, but I've got no experience with Android Auto.

Car Scanner has a profile for Gen5 "Primes" that provides hybrid-type data.
No dials on CarPlay.
