Garmin Tempe - accuracy?

SMICKF

Hi,

I've recently bought a Garmin Tempe to go with my Montana and it works well. It was easy to pair up and the unit is neat and small. I'm very pleased with it. I'm well aware of the limitations of siting a thermometer and how you need to put it so it's not going to be influenced by heat/cold sources so it only samples the ambient air temperature.

My query is really out of interest rather than worry.

What is the accuracy of the Garmin Tempe?

I understand that the figures aren't published. I wondered if anyone had any comparative evidence of the Tempe's accuracy? Has anyone ever compared the Tempe to a recognised accurate temperature?

I'm just a normal chap in a normal domestic environment, and I don't have access to a decent accurate thermometer, but someone has one somewhere. Has anyone every checked the Tempe?

Has Garmin ever checked them?
If so, surely they must know something.

Regards,
Mick

    According to the information found here, the Tempe is only accurate, if paired to a watch with barometric altimeter, which is recalibrated every 10 minutes. Which watches have a barometric altimeter which can be autocalibrated? There is no information about this, in the review about the Tempe mentioned above.

    This is NOT true!!!

    According to the description above it is true, and also according to my own little personal experience it is also true. GPS off, unstable temperature readings, GPS on, stable temperature readings, when paired to a Fenix 6 and barometric pressure sensor is set to autocalibrate.

    How do you explain that the tempe works perfectly with devices that do not have a barometric altimeter at all? What kind of laws of physics are applied, that make a simple temperature sensor change its reading when another totally unrelated sensor is calibrated? How can presence or lack of information about altitude influence temperature measurement? Can you point me to any other thermometer, that needs to know altitude to show correct temperature? What would be the point of making such a device? Do you know how these things work? Do you know the details of the ANT+ profile the tempe uses for communication with devices? Are you aware, that this is a one-way communication only, and that the tempe does not receive ANY data from ANY external source?

    My tests where emirical data which I cannot explain. But since I found out that it is possible to have an ECG sensor connected to a Rasperri with sends the data to an MQTT brocker in Home Assistant, my interest in the Tempe and it s options is gone. It is possible to repace the ECG sensor in the above setup by a temperature sensor, than we can use it as a Tempe replacement and as a Core temperature sensor replacement, which do not require these kind of discussions.

    We published the missing information from the Garmin costumer service which was posted here which someone removed recently from this thread here. For all those who want to get the maximal accuracy of the Tempe, and for all those who want to advice costumers how to use the Tempe in an optimal way:
