Our recommendations for best practice usage scenario when collecting data from the Stages Power meter on a Garmin Edge 810. Many of these tips also apply to the older model, Edge 800, which uses the same pairing steps and many of the same settings.
Preface: Head unit set up can affect the quality of the data captured from your Stages Power meter. These are the recommended settings used by Stages Power meter staff and athletes. We’ve also compiled known issues affecting this particular head unit, as well as our best recommendations to deal with these problems.
General set up recommendations:
Overview: These recommendations come from our daily usage of the Garmin Edge 810 head unit. They are our best recommendations to get the best possible data capture from your head unit, with the least possible chance for lost connections, data, and general connectivity between your Stages Power meter and Garmin Edge 810 head unit.
Key areas of focus: Manually enter ANT+ ID; Set data collection to once-per-second; Update head unit firmware
There are two ways to pair a power meter to your Garmin Edge 810. The more common way is to ‘search’ for it, which we strongly advise against. Our reasoning is that if your previously ‘searched’ sensor is not available the head unit will go back into search mode and either find another power meter sensor in close proximity or revert to ‘0’ for a device ID.
If you manually enter the ANT+ ID for your personal Stages Power meter, your Garmin Edge 810 will only look for the meter with the ID you’ve input.
To manually enter your ANT+ ID follow this key path:
Turn on head unit > Press ‘Tools’ icon (screwdriver and wrench on the main screen), to get to the main menu and then follow this key path: Bike Profiles > Bike 1 (or whatever bike you’re working on) > Barbell Icon (ANT+ Power) > Sensor Details > Sensor ID (Enter) > check icon (Done)
Note: Garmin offers space for and ANT+ ID with up to 7 digits, if your ANT+ ID is less than 7 digits, you must start by entering 0s, to account for digit discrepancy, before entering your unique Stages Power ANT+ ID.
You must zero reset your Stages Power meter after installation, and we recommend zero resetting once-per-week to keep your meter reading with maximal consistency.
To Zero Reset using your Edge 810:
Rotate your Stages Power one full revolution to wake the meter, then orient it in the 6 o’clock position, click the ‘Calibrate’ function in the Garmin’s ANT+ Power profile page.
The ‘Calibrate’ Zero Reset function can be found through this key path:
Press ‘Tools’ icon (screwdriver and wrench on the main screen), to get to the main menu and then follow this key path: Bike Profiles> Bike 1 (or whatever bike you’re working on)>Barbell Icon (ANT+ Power)>Calibrate>Calibrate (again)
Your Garmin Edge 810 head unit will then return a Zero Reset (Calibration) value of 890 +/- 50 counts.
Once-per-second recording. The Garmin Edge 810 head unit has two data recording options. The function ‘smart recording’ purposefully drops data packets when the information looks the same in order to save memory space. This is a hold over from when Garmin was building units during a time when on-board memory was much more expensive. The Edge 810 has a 22mb of on board data storage. This is enough to store 1 month to 6 months of ride data, depending on ride frequency and duration, when using the once-per-second recording option. We absolutely recommend recording at once-per-second and downloading more frequently.
To set once-per-second recording, follow this key path:
Press ‘Tools’ icon (screwdriver and wrench on the main screen), to get to the main menu and then follow this key path: Down Arrow > System > Data Recording > Recording Interval > Every Second
While you’re in this screen of ‘Data Rec’ you may also be interested to consider Zero or Non-Zero Avg for your Cadence and Power averages; this is a personal preference and one you may run by your coach. Non-Zero averaging doesn’t count the 0s produced by not pedaling, whereas Zero averaging counts those Zeros in the overall average as presented by your head unit.
Much like our ability to better the performance periodically by continually working to improve our Stages Power meter firmware, Garmin works hard to keep even its older head units in top working condition. With regards to this we strongly recommend checking and updating your Garmin Head Unit firmware monthly (if available).
To update your head unit firmware:
Download Garmin WebUpdater: Garmin WebUpdater
Connect device to PC, follow prompts in Garmin Web Updater application.
ANT+ signal interruption due to orientation, shrouding, water, or rider mass interference
Cause: the Stages Power meter puts out a signal capable of spanning distances of 10-15 feet, so long as the receiving radio is properly oriented. Putting a head unit in a rider’s pocket, wrist, or mounting it within any sort of aero shroud, or on top of a bar mounted water bottle will cause signal interference and data loss.
Effect: signal drops and data loss.
Solution: make sure the Garmin head unit is in the open with reasonably clear line of sight to the Stages Power meter.
Further recommendations: do not use bar mounted combo bottle/head unit mounts. Do not cover the front of the Garmin head unit with plastic, carbon fiber or other material.
Firmware bug causing 810 head unit to intermittently halve the recorded power value
Cause: Firmware installed at launch of new Edge 510 and 810 devices prevented accurate collection of otherwise normal data packet transmission from sensor.
Effect: lower than normal power reading, by about half the expected wattage
Solution: update Edge 810 device to most current firmware
Further recommendations: It is best practice to check for new firmware for both your Garmin head unit and Stages Power meter once per month.
If you still have additional questions about setting up your new power meter, please feel free to open up a support ticket with Stages Cycling or Stages Cycling EU to get help with your power meter and head unit.
