These latest reviews got me worried, so I just tested it. The HEX works for me! I have been using this HEX since it first came out on my Fenix 3, and just 1 week ago downloaded both data fields to put on my new Fenix 6x pro. The Hex communicates just fine with both watches, and with the HEX android phone app. (although the phone app is no longer available on Play store, and trying to transfer the app to a different phone brings up a Humon log on screen, which doesn't want to accept my info). When I set up the 6x pro, I had forgotten the steps and incorrectly let the 6x look for a new device. The watch recognized the HEX and displayed data, but the Humon app pages wouldn't work. Doing it the correct way (removing the HEX ID from the Garmin) let the Humon apps work, and they continue to work as of 5 minutes ago. Don't know why it stopped woprking for others, hope it doesn't happen to me. Fantastic device - even showed up an injury that I thought was a muscle tear - until I saw the HEX data. Showed the graphs to the docs and they diagnosed a sport related injury to an artery in the leg! The HEX data was confirmed by MRI and CAT scans!

Confirmed no longer working on 830. As of about late 2019, after Humon went out of business and the iPhone ap stopped working, the device would still sync with my 830 and show the interval and endurance fields. Better than nothing. As of 2021, it will no longer sync. The 830 has been updated several times since then and clearly the Humon IQ field has not so the Garmin can't find the data stream. Oh well.

I've used Humon for several years, both with me and my son. It's a great bit of kit, really gives supporting data for muscle state to overlay on heart rate. Also great for step tests, and having it integrated with Garmin is a real plus. Only problem is that it's now stopped working with Garmin: The flashing light on Humon goes green, but the Fenix 6x just says "searching for Humon". Tried soft reset, no deal. Tried deal... No idea what to do now.

There is an app for HUMON called MOXZONES in the GARMIN store that works with almost all GARMIN cycle computers and watches. (Does not work with FENIX3, Forerunner® 230 or Forerunner® 235 due to low memory) It gives you the data on HUMON and a graph IN REAL TIME. The price of the application is € 6.

No connection with 830

Same issue here with my Edge 830: no connection to Humon, even though it works on my FR935?!

My Edge 830 has trouble finding the sensor for quite awhile. I've tried to uninstall the app and reinstall it back again but no success. I also used it with my Fénix 5X and I have no issues.

Hallo Humon-Team, ich laufe ca. 50 km die Woche und verwende den Humon Hex Sensor jetzt seit über einem Monat. Der Sensor hat mir ein wirklich viel besseres Verständnis für meinen Körper gegeben. Er ist jeden Cent wert. Natürlich gibt es noch Verbesserungspotential: 1. Es würde mir sehr helfen, wenn die Garmin Uhr ein Vibrations- oder/und Akustik-Indikator für einen Farbwechsel hätte. Grade wenn ich versuche in der Gelben-Zone zu laufen, schaue ich nicht alle paar Sekunden auf die Uhr. 2. Eine zusätzliche Farbe für das Einlaufen wäre auch super. 3. Eine Server zu Server Synchronisation mit Garmin-Connect wäre echt Klasse. Macht weiter so, ihr seid auf richtigen Weg :-) Mfg Winniwar Hi Humon Team, I run about 50 km a week and have been using the Humon Hex Sensor for over a month now. The sensor gave me a really much better understanding of my body. He is worth every cent. Of course there is room for improvement: 1. It would help a lot if the Garmin watch had a vibration or / and acoustic indicator for a color change. Whenever I try to run in the yellow zone, I do not look at the clock every few seconds. 2. An additional color for the warm up phase would also be great. 3. A server2server synchronization with Garmin-Connect would be very nice. Keep up the good work; you are on the right track :-) winniwar

I've been trying off and on for over a year now to get this to work on my Garmin 1030. I've installed the IQ Field on my iPhone, synced to the Garmin via Garmin connect, and all I see is "Finding Hex" in the data field. I've tried every possible combination of installing, uninstalling, turning devices on and off, removing the field and restarting garmins, phone, computers, entering the serial number (the long GUID) in upper and lower case), burning sage and dancing by the full moon. It just doesn't work on the Garmin 1030. I've also searched and while many seem to get it to work on the Garmin watches, I've not yet seen anyone demo it on a 1030 or similar. The funny thing is if I use the BSXInsight IQ data field it picks up the Humon's signal instantly. It's just an ANT+ field, so why can't the Humon IQ field pick it up as easily?

My one complaint is that after my activity has been uploaded it does not show the color trends as in the humon app

Hi Robert, We've just added the colored zones to the FIT File recorded by Garmin so that you can import them into your favorite training platform. Thanks, Humon

This data field gives all the info the mobile app gives with the exception of the recent history trend chart (but really, there probably isn't room for that on the watch screen). The recent update showing colors means I can now go for a run and don't have to hold my phone with the screen on to see the data; I can see everything on my watch. It went from an okay data field to a great one with this update. The only thing it's missing is a way to see in Garmin Connect the color zones (so looking back on an activity I could see where I was in recovery / limit / etc in addition to raw numbers), but that may not be doable.

Connected to FR935, it looses the CONNECT IQ connection a lot of times while the SMO2 value, directly obtained from the sensor remains connected. This last value however is not recorded in the fit file. Only the CONNECT IQ value is. Noticed something very interesting today: while riding indoor bike, positioning my pedals on the middle of my foot, the SMO2 values were declining more than positioning my forefoot on the pedal. Heart rate, gear and RPM values remained the same. I think this is because my calves are more activated when placing forefoot on the pedal. Overall I felt it was easier biking putting my forefoot on the pedal.

I am waiting until it will display more data in real time, like HbT and current zone, perfectly in color

when the app works it works well. wasn't made compatible with the VivoActive3, but works on my older VivoactiveHR. it does NOT require the phone to be synced to work on the garmin. After starting Hex (multi flash then red light) double push the power button, and it will go blue, then slow flash green... at this time the vaHR can pick up the data stream. occasionally i have to start run, exit, start run for the stream to be seen. (check its sending data before you hit go) when the data stream records, the data shows on garmin and is quite interested. should you not get the stream to record, even though the hex records 64 hrs of data, there's no current way to get the data out after the fact. a serious amount of potential with this device, and it's amazing how (for me) you can see when your pushing over your limit before you feel it. u can find your sweet spot where supply matches demand, you can see your legs recover after pushing a hill... i'm excited for this device, just need the apps to catch up to it.

Cannot pair with Vivoactive HR, which is listed as being compatible with Hex. The Humon datafield app-file does appear within the list of installed components on the Vivoactive HR, when the list is shown by the IQ Connect Manager. The Vivoactive HR does receive external ANT+ sensors, including a Garmin heartstrap, and a Quark powermeter. The Humon sensor data (SMO2 and THgb) does appear on PerfPro. So I'm wondering if the Humon software add-on (datafield for IQ Connect) is somehow not allowing pairing with Vivoactive HR. I'm really excited about the Hex producing muscle oxymetry on PerfPro!!!

Does what it should, however: * requires the phone for every workout to pair with my Fenix 3 * only saves integer values for SmO2 to the fit file.
