Get device temperature in smaller intervals (Venu 2)

Why are you doing it in the background? What app type? How do you get it now?

I have an app of type Watch App that should log the device temperature for a longer period of time (usually up to 30 minutes) during which the app can't be constantly kept open due to the device screen turning off after some time...

I am currently doing it retrospectively when the logging ends (saving Start and End timestamp using a Menu, then using SensorHistory to get the values, saving it in CSV format to a Settings property and calculating min/max) but SensorHistory only gives one value every ~5 minutes...

You mean if you read Sensor.getInfo().temperature every 30 seconds, it only ever changes in 5 minute intervals?

I currently use the sensor history to get the values after the logging ends, so no Sensor.getInfo involved as I can't keep the app running....

The values returned by the SensorHistory only have an interval of 5 minutes....

Why can't you keep the watch-app running? My app keeps running for hours.

How would I do that?

Just set a periodic timer that runs Sensor.getInfo and appends time and value to an array?

Yeah, start with that. Or even just display it + the time it was read, and then you can see if it changes when you get it out from your fridge and put it under the sun.

Try it on a real device,  with some newer devices,  you should see the internal temp.

Try my temps app and if you don't have a tempe sensor you'll see Sensor.getInfo().temperature.

With your app, I can see the internal temperature in the top field ("internal"). Does that mean I can just run Sensor.getInfo().temperature on my real device and it will work even if it didn't work in the sim?
