What is it?

The Portal Media Bluetooth TPMS module lets you monitor tire pressure wirelessly via Bluetooth.

The Verdict:

Portal Media's Bluetooth TPMS improves on the last generation of devices by allowing wireless communication via Bluetooth. The module is sleeker and reception appears improved. Once the kinks are worked out of the Android app, the Bluetooth TPMS module will be an awesome addition to any compatible car.


Description:

Quite a few years ago at mp3Car's first national car PC meet, I was lucky enough to win a prize for having as many as 19 USB devices connected to my car PC. The prize received was USB number 20, a car PC connected tire pressure monitoring system (TPMS) from Portal Media. Many years and several dead sensor batteries later, the device had served me well, but it was time for an upgrade. Luckily, the guys at Portal Media have been busy at work improving on their existing technology. For years it's seemed that the Bluetooth variant of their TPMS devices was simply an idea in our mp3Car forum, but the time has arrived, and the device really exists. I've been privileged to spend the last few weeks testing this new device out and getting to see if the wireless abilities actually improved the experience.


Let's get the obvious information out of the way first. The tire sensors required for the Bluetooth TPMS device must be professionally installed, so be sure to account for the cost of installation when considering this purchase. My cost was roughly $30/tire, but yours can vary. Also, as if this review, there is no Apple or Windows application that will work with the Bluetooth TPMS module. It's unknown whether this will be created by Portal Media in the near future, but as the mp3Car community is founded on the idea of tinkering and fitting square pegs in round holes, I'm sure solutions will exist shortly. Once the sensors are installed in the tires, the rest of the process of setting the system up is a breeze. The TPMS module is smaller and sleeker this time around, so it's easy to plug into any available 12v source and slide in a glove box or other compartment. It's recommended to install the device in a centralized location in relation to the tire sensors, but I've had far more success with reception despite installation location in comparison to the USB unit. Once the device is mounted and powered, the Android application will need to be downloaded from the Play Store. Once the app is installed, its time to begin the process of synchronizing the tire sensors to the Bluetooth module. Check out the video below on the steps required here.


The Android application for the Bluetooth TPMS is very easy to use. The user interface is very simple, and once the sensors are learned, it will quickly and accurately report sensor information. In the app settings, there are a large number of variables which control sensor alert notifications and display preferences. The app is not without faults though. I have the application installed on three of my Android devices; A Samsung tablet with QHD resolution, a Samsung smartphone with HD resolution, and the ODROID X-2 Android low resolution head unit. Each instance gives me a different take on the app. The smartphone displays the perfect scaling of text, buttons, and images. On the tablet, the buttons are very small and often a chore to press, and the vehicle image and text does not scale to make use of the added real estate. The ODROID's low resolution allows for the buttons and images to display correctly, but the text is too large for the bubble window it's presented in. Portal Media has acknowledged some of the drawbacks of the app, and is aggressively working to correct the issues.




Ultimately, the experience of being free of the installed car PC screen when dealing with my tire pressure is a much needed improvement. Rather than having to run back and forth between tires and the monitor to check pressure levels, I can take my tablet with me to each tire. I'll still receive alert notifications through my Android car PC, but the flexibility to use an additional screen when I choose is awesome.

The Positive:

Module has a sleeker and smaller profile
Tire sensor reception seems improved
Android ability allows for cross-device usage
Easy learning and setup process



The Negative:

No current iPod or Windows support
Android app is functional, but will need work



The Verdict:

Portal Media's Bluetooth TPMS improves on the last generation of devices by allowing wireless communication via Bluetooth. The module is sleeker and reception appears improved. Once the kinks are worked out of the Android app, the Bluetooth TPMS module will be an awesome addition to any compatible car.

FYI the device was not available at the time of this review, and I've received no word as to where it can be found now. I'll contact the developer and reply soon.
Since that blog post gave me the idea of monitoring tire pressure from my android head unit installation, I found an equivalent (perhaps better) setup: the Steelmate TPMS-8886.
It has external module and a bluetooth enabled cigarette lighter receiver. You can connect via iphone or android smartphones and monitoring in real-time tire pressure and temperature.
After a night of insane googling I found the best price in an online netherland shop, navco.nl, selling it for 139 euros with only 9,95 euros shipping to Italy.
GB friends can use steel-mate.co.uk (ships only to GB and Ireland) pricing it 118 (about 159 euros); rest of the world, I found the best price at aliexpress at 218 USD, free shipping.

Don't know if it's already known at the forum, I'm away for a long time..
Not sure if Portal media is still going, website is non existent, only old links to youtube videos showing off carpc with CF 2. Maybe Sonicxtacy02 can shed some light on the subject and maybe provide a new link to them. SNO
