Get device temperature in smaller intervals (Venu 2)

What you see for internal ia SensoeHistory.getTemperatureHistoy.  What you see for Temp is Sensore.getInfo().temperature.  And this can vary based on specific devices,

I see "--" for Tempe...

So does my Venu 2 just not support this method of getting the internal temperature?

I can't use SensorHistory due to it only outputting one value every 5 minutes...

I forget when this started to work, but probably doesn't work with the venu 2

So I can't get the temperature in intervals smaller than what's provided by SensorHistory?

Seems you can't on a venu2..  On a fr570, it works as I described,

Venu2 doesn't have a built in thermometer: https://www.garmin.com/en-US/p/707538/#specs

Thermometer	yes (tempe sensor required)

I bought a new Tempe a year ago. I had to comb the whole internet, and this was probably one of the few remaining new items in Europe at any retailer.

As for knowing the temperature: as far as I understand there's no really accurate way to know either the air temperature or the skin temperature using the built-in thermometer, because it is not designed for either of these. It's part of the barometer (which kind of implies that it measures air temperature) but it's also affected by your heat, and probably more importantly by your watch's heat.

There are other external devices, like Core, that are made to measure your core temperature.

I developed a couple for simple sensors that pass on ambient temp over BLE.  One using a raspberry pi and the other. and ESP32 for a cost in the $25us range, and right now with a battery life of about 4 hours.  This might work based on the applicaion, and if steady power is available.
