Sleep skin temperature not working, what's the problem?

Same here. T8 47mm. "--" displayed

I’m in the same boat. I contacted Garmin; and, I spoke to David. He mentioned that I’m the eighth caller to have the problem of the skin temperature not working on my Tactix 8 Applied Ballistics Elite (Solar).

David mentioned his team is creating a firmware update, and it is slated to be released in May 2025, which will resolve this issue.

I recommend you contact Garmin Support so they know there is more than eight users experiencing this problem.

Today, 19-March-2025, I reset my Tactix 8 Applied Ballistics Elite; and, I also reset the Garmin Connect application on my iPhone; and, I will see if the skin temperature works after three sleep-nights.

Check 6!

Not working for me either

My 51mm AMOLED Standard doesn't show skin temperature either.

How is “we know there is a problem, we’ll fix it in May” an acceptable solution for a $1,000+ watch that’s available for sale? 

This is a good question. I have no idea for this long long way to fix. 

I'm happy that there is a response from Garmin. This watch has been solid with only the skin temp not working for me. I'm willing to wait for a solid update that doesn't introduce new bugs. 

I found the "Core (Body) Temperature" app on Connect IQ as an alternative while we are waiting for a fix.  It gives a nightly temperature during sleep.
