I’m pretty Meh on it, TBH. I got it years ago, struggled to get it working and it has been sitting ever since. The support from Garmin and Wahoo just wasn’t there when I got it.
I just got it functioning this week so that is literally some of the first data I have seen from it.
For this specific use, it is fine…I am using a Garmin watch to view data real-time and the above data is from the Core app. From what I can tell, the temp data does not export with the Garmin files, though.
Thanks for info…I actually love riding in the hot weather. I thrive while others wilt…but growing up in DC will do that for you! 
I’m mostly doing this just to see if I can blunt the edge of altitude at SBT GRVL…IIRC, Jonathan and Chad both said it could have some beneit, but nowhere near as much as actually acclimatizing at altitude. Since I can’t spend 3 weeks in Steamboat ahead of the race, this is my best option, I guess…
