Each sensor in the SensorPush app shows the time of its most recent reading, labeled LAST READING, on the main "Devices" screen. If the app hasn't received a new reading from a sensor for more than 15 minutes, that label turns red and an exclamation point (!) appears next to it. It's the app's way of telling you that what you're seeing may be out of date.
The good news is that this usually has a simple cause. The steps below will help you figure out where the readings are getting held up.
First, Refresh the App
When you open the app, it can take a few moments to fetch the latest data. To force an update, go to the main "Devices" screen, scroll to the top of the list and pull downward, the same way you'd check for new messages in an email app. Give it a few seconds to finish.
How Readings Reach Your App
Your sensors take a reading every minute and store them in their own memory. Those readings reach the app in one of two ways:
- Directly over Bluetooth, when your phone or tablet is within range of the sensor (usually the same room or a nearby room). This only happens when Bluetooth is switched on in the SensorPush app's settings (from the main "Devices" screen, tap the button in the top left, then look under "Configuration").
- Through a SensorPush WiFi Gateway, which picks up sensors within its range and sends their readings to the SensorPush cloud, so your app can show them from anywhere.
If you don't use a gateway, it's normal for readings to stop updating while you're away from the sensor. Nothing is lost: the sensor keeps recording, and the app downloads the missed readings the next time you open it nearby. The HT1 stores about 20 days of readings, the HTP.xw about 30 days and the HT.w about 45 days.
Check Where the Last Reading Came From
Tap the sensor to open its detail screen and scroll down below the graphs to the Summary section (shown as "SUMMARY" on iPhone and iPad).
- If a gateway has heard the sensor in the last 15 minutes, you'll see Connected via Gateway, followed by the gateway's name, its signal strength and how long ago it last heard the sensor.
- If not, you'll see Last seen with the date and time the sensor was last heard from, and Last seen strength showing its signal strength at that time.
If You Use a Gateway
- Check that the gateway is online. Find your gateway in the main "Devices" list. If it shows as OFFLINE, start with My gateway is offline / cannot access the internet. (It's normal for a gateway to show as offline for a moment right after you open the app. Here's why.)
- If the gateway is online but one sensor is stale, the sensor is most likely too far from the gateway or blocked by walls, metal or a refrigerator or freezer. Try moving the sensor next to the gateway for a few minutes. If it starts updating, it's a range issue, and this article explains how to improve the connection.
- If all of your sensors stopped at the same time, the gateway is the likely cause. Unplug it, wait about 10 seconds and plug it back in.
If You Use Bluetooth Only
- Bring your phone within a few feet of the sensor and open the app.
- Make sure Bluetooth is turned on in your phone's settings, and also inside the SensorPush app: from the main "Devices" screen, tap the button in the top left to open app settings, and under "Configuration," switch Bluetooth ON.
- On Android, keep the app running reliably in the background by following these steps to turn off battery optimization.
If the Sensor Still Isn't Updating
If the sensor isn't heard by your phone or your gateway even up close, the battery is the most common cause. Check the battery voltage in the Summary section, and if the battery has recently been changed, see Why is my sensor not working after I changed the battery? For more steps, see My sensor isn't working. Help!
