Use your Apple Watch as a heart rate monitor with your Wahoo ELEMNT — no chest strap, no extra hardware. This guide covers first-time pairing and the per-ride connection procedure.

What You'll Need

  • •Apple Watch (watchOS 10 or later)
  • •iPhone (iOS 15 or later)
  • •HRM app installed on both Apple Watch and iPhone — download here
  • •A compatible Wahoo ELEMNT (see compatibility below)

  • ELEMNT ACE
  • ELEMNT ROAM V1 / V2 / V3
  • ELEMNT BOLT V1 / V2 / V3

One Phone App at a Time

Wahoo only allows one Bluetooth app connected to your iPhone simultaneously. The Wahoo app must be closed before HRM can connect. This is the most common reason it doesn't work.

Initial Setup

  1. 1 Terminate the Wahoo app fully on your iPhone. Swipe it away in the app switcher.
  2. 2
    Open HRM on your iPhone and Apple Watch, then press Start on the Watch. Bring your iPhone close to the ELEMNT.

    Wahoo only discovers sensors broadcasting a plausible heart rate (above ~60 BPM). Make sure your Watch is actively measuring before proceeding.

  3. 3 On your Wahoo: go to Settings → Add Sensor. The sensor with the highest signal strength will appear — this should be your iPhone running HRM.
  4. 4 Select Add, then Save to complete pairing.

Setup for Every Ride

  1. 1 Terminate the Wahoo app on your iPhone.
  2. 2 Open HRM on iPhone and Apple Watch, press Start on the Watch.
  3. 3 Power on your Wahoo ELEMNT. HRM connects automatically.
  4. 4 Ride.
  5. 5 After your ride: press Stop on the Watch, terminate HRM, then open the Wahoo app to sync.

If the Connection Drops

Re-pair to Reconnect

If the connection drops mid-ride, Wahoo won't automatically reconnect to the sensor in the same session. You'll need to delete and re-pair. The process takes about 30 seconds once you know the steps.

  1. 1 On your Wahoo: delete the existing HRM App sensor from your sensor list.
  2. 2 Re-pair following the Initial Setup steps above.
