What you need to run Sentinel

The plan, the phone, the wearable and the health permissions Sentinel needs before a session can read anything.

Same on every platform Updated

What this does

Sentinel monitors physiology, not trading activity, so the setup is hardware first. Four things have to be in place before a session reads anything: the plan, a phone with the VEXA app, something on your body that measures heart rate, and permission for VEXA to read that measurement.

Before you start

The plan. Sentinel is Pro. Your first week of Full Access opens it to everyone, and after that it needs Pro.

The phone. Heart rate reaches VEXA through the iPhone or Android app. The phone talks to your watch or your Bluetooth strap and writes the readings to your account. The web dashboard is a display and a control panel: it can start and stop a session and it shows every vital live, but it never measures anything itself.

The wearable. Seven devices are supported in total, and any one platform offers six of them. Some send beat-to-beat data, which is what heart rate variability is calculated from, and some do not. See Which heart rate devices work.

The permission. iPhone asks through Apple Health. Android asks through Health Connect. The two are set up differently and are covered in their own articles.

Where a session can be started. Web, iPhone and Android phone. iPad cannot start one, it mirrors a session running on your phone. On an Android tablet the start control is on screen because the tablet reuses the phone’s card, but the tablet has no heart rate source of its own, so start your session on the phone. See Sentinel on iPad and Android tablet.

Steps

  1. Open VEXA Sentinel from the sidebar.
  2. Open the Settings tab.
  3. Under Wearable Source, pick the device you own.
  4. Follow the setup steps in the modal that opens, then close it.
  5. Open the VEXA app on your phone and leave it running, with your watch or strap on.
  1. Open Home, then tap Sentinel.
  2. If the screen asks you to connect Apple Health, tap Connect HealthKit and allow every category. See Connect Apple Health.
  3. Tap the gear icon, then Sentinel Settings.
  4. Under Wearable Source, pick your device and follow the Set up link next to it.
  5. Put the watch or strap on and return to the Sentinel screen.
  1. Open Sentinel from the sidebar to confirm the screen is there.
  2. Do the rest of the setup on your iPhone or Android phone. iPad has no health access of its own and cannot start a session.
  1. Open Home, then tap Sentinel.
  2. Tap the gear icon (Settings), then Sentinel Settings.
  3. Under Wearable source, pick your device and follow the setup sheet.
  4. Grant the Health Connect permissions if you are using a Wear OS watch. See Connect Health Connect.
  5. Put the watch or strap on and return to the Sentinel screen.
  1. Open Sentinel from the sidebar to confirm the screen is there.
  2. Do the rest of the setup on your phone. The tablet’s Health Connect row opens a pane, but the button on it does not open Health Connect.

What you should see

On the Sentinel screen, your chosen device named next to the live badge once a session starts, and a beats-per-minute figure that changes every few seconds.

In settings, the wearable section shows Connected rather than Not Connected after a successful pair.

The baseline card reads “0 / 20 sessions” until you have run some sessions. That is expected on day one and Sentinel still works, on safe starting thresholds.

If it doesn’t work

The Sentinel page is a locked preview. Your plan does not include it. See Why a feature is locked.

The session runs but the heart rate stays blank. The phone is not connected to the wearable, or the wearable is being held by another app. Chest straps pair with one app at a time. See Which heart rate devices work.

iPhone never asked for Apple Health access. iOS only asks once. If you declined, it will not ask again and you have to grant it in the iOS Settings app. See Connect Apple Health.
