Getting data from Garmin Zumo Tire Pressure Monitor Sensor (TPMS)

I have a project where we need to monitor tire pressure. We bought a Garmin Zumo Tire Pressure Monitor Sensor (TPMS).

https://buy.garmin.com/en-US/US/p/131744

I downloaded Simulant and Antware ii, and bought an Ant USB-m stick.
The USB-m stick connects well with Simulant. I can pick the device type to simulate from the Simulant dropdown and turn it on (great). But I've tried every sort of Display Device or Remote Control there is on the list. The message shows up "searching for master device...." then it gives the message "Search Timeout!" and "Channel closed."

I haven't gone through enough Ant Basics to know why I can't connect to the Tire Pressure Sensor. But for starters, I see that this Garmin sensor is not listed int he Ant directory https://www.thisisant.com/directory
I see lot of other Garmin products listed along with their profile category. The Tire Pressure Sensor is not there, and there isn't any profile that would seemingly match what such a sensor would be.

So my understanding is the reason why I can't connect to the Tire Pressure Sensor is because there is no device I can choose that would match such a thing.

Any tips on using Python or C++ or using some other tool to connect directly to the USB-m and display all Ant devices it sees? Then be able to pair with it and get data from it?

It would be very nice to be able to use this sensor in our project because it is so small and compact and the battery life is about 2 months, and most importantly is off the shelf and easy to replace.

Hi Andre,

While the Garmin TPMS product does use ANT technology, it does not use an ANT+ standard protocol of communication. Therefore, our toolsets do not support this protocol, nor do we have documentation covering its design, or how to connect to it.

To connect to a Garmin TPMS sensor, please contact Garmin directly, asking for the ANT communication protocol for Garmin TPMS.

Hi Andre, did you get any further with the Garmin TPMS? I am trying to monitor it's output too.
