Iām looking at getting a new watch, been using Watch for years but TR wonāt work with Apple Watch or Apple Health.
At the moment the only way I can write to Health is running a Workout on the Watch or running Zwift at the same time, which can take HR from a Watch and write to Health.
Is there a watch that can send (over Bluetooth) HR to TR, and will also write the workout to Apple Health?
Iām thinking a Garmin might?
Not a watch, but a external optical HRM
Scoscheās Rhythm+ 2.0
(get the second generation)
you can even use it for full IM!
I meanā¦ you have 24 hours to finish, but i think you have that covered!
I have a Fenix 6X but personally donāt use the Health App. I just checked - you can add data from garmin connect to health. It seems as it will sync all the metrics garmin connect gathers from the watch such as hr, rhr, sleep, weight, steps, weight, workouts of course and other metrics.
I broadcast HR from my garmin fenix 5s to TR.
Iād forget about an optical HR sensor for TR and go for a HR strap. For health data, Iām sure youāll get better than it, but I use a vivioactive 3, mainly because I like the aesthetics of it.
and Strava app on Watch: https://support.strava.com/hc/en-us/articles/115000161184-Strava-Apple-Watch-App however I donāt think Stravaās Watch app will track swimming.
I use a Garmin 745 and sync it to health. I donāt use health for anything other than a data collection point (my Oura picks up activities from there) but it all works well.
I had high hopes for Health but IMHO it is not a good repository. On the other hand Health is ok for (limited) data exchange. TrainingPeaks (the free edition) does a great job at archiving all the original data files with whatever was collected at the time (e.g. GPS tracks, HR, etc.).
Health is just a health repository so it works well for that, it just doesnāt do performance which is fine by me. Iām working with TrainingPeaks and TR for performance.
I may have forgotten the all important āit must be bluetoothā 
I only use iPhone, iPad and Apple TV
Edit:
Ive found that they added bluetooth broadcasting to the 6 last summer
Ask apple to create a HRM?
Just get the strap or ohrmā¦ you will be happy with itā¦
thats what I use on apple devicesā¦
Personal preference - because TR fails to collect temperature, HRV within a ride, and left/right power to name the big ones, my primary recording device when doing indoor workouts on the trainer is my Garmin bike computer.
If I was a triathlete, Iād likely go with a high-end Garmin watch for running/swimming and Edge for cycling. Garmin syncs to Health.
I agree with thisā¦
I have a 935ā¦ works greatā¦ I also have a cheap (ish) garmin bike computer for outdoor rides (used as a mirror of the 935).
Garmin is about to release the 955, and it will probably have everything you will ever needā¦ (except an accurate OHRM)ā¦
Is there an ETA?
not that I am awareā¦ but they release the 9 line every 2 yearsā¦
945 was 2 years agoā¦
935 was around this time 4 years agoā¦
Will see how the pandemic have affect their plansā¦
Apparently rumor is one model will have LTEā¦ thatās a cool featureā¦
It is not the watch but TrainerRoad that needs to get data into Apple Health.
In essence there is no real easy way of doing it without doing as you have been doing; running something else that does write data to Apple Health.
Yes a Garmin watch will put a workout into Apple Health but just as the Apple Watch you will need to run a workout on the Garmin whilst also running TrainerRoad.
My only hope is that all the adaptive training talk will prompt TrainerRoad into linking into Apple Health for a more complete dataset.
My current workaround is with a Wahoo Rival and a Tickr. Just connect the watch to the Kickr, Tickr and power meter. Then run an āindoor bikeā session to record to add into Apple Health.
Farming for everything, Fenix+810+v3+connect App, nothing better. The data you get for free from the Connect App itself blows everything out of the water, and I have an Apple Watch and Suunto.
Why do I find this annoying? 
I donāt want two workouts, I want one! I have been running Apple workout simultaneously this year but inevitably sometimes forget.
My quest to simplify things always seems to complicate things. I donāt really need HR data after all, I just want to inform SkyNet really.
Hey @bbarrera, what way do you run this setup? Iām getting tired of my Garmin telling me Iām unproductive the whole time as itās not accounting for my TR ridesš . Connect TR to app via BT and record to Garmin with Ant+?
Easiest and also if you love the TR app is to do something like what I did:
Alternative is to sync TR outdoor workouts to your Garmin, and only use Garmin for the workout. Eventually I did this to test out using resistance mode instead of Erg, and now prefer this for a couple reasons.
