Frequently Asked Questions

Setup

How do I set up my new gateway?

Gateway set up is very straightforward. There are a few pointers to help you get started when it arrives. You can find them on the gateway set up page.

SensorPush G1 WiFi Gateway


How do I set up my new sensor?

  • Go to sensorpush.com/apps from your iOS or Android device and install the SensorPush app.
  • Open the app. Click the Add Sensor button at the top right corner of the screen.
  • Hold your sensor against the screen and keep it over the moving image.
  • After a few moments, the app will connect and move to the next screen. There you can give the sensor a name (e.g. "Attic" or "Wine Cellar"). You can also set up alerts if you like. Don't worry! You can easily return to this screen at any time to change these settings.

I tried that and nothing's happening. Now what?

We're really sorry you're having trouble. The following steps will almost certainly get the system up and running though.

  • Turn Bluetooth off in your phone's settings, wait a moment and then turn it back on.
  • Then retry the setup process. Be sure that you go back to the main screen of the app and click "Add Sensor" again to fully restart the process when you try again.
  • If that fails, completely exit the app and reboot your phone. Then start over, making sure that you begin from the home screen of the app.

If none of the above has worked and you have a Gateway device that you have already paired, it is possible that the Bluetooth is switched off in the SensorPush app itself. That gets turned off after you start using a Gateway. To turn it temporarily back on for pairing do the following:

  • Open the app, and from the main screen (the screen with the word "Devices" at the top) select the button in the top left to open app settings.
  • Once in app settings you'll notice a section called "Configuration" with a switch for Bluetooth. Switch it ON (you can turn it off again once all new devices are paired).

If you're still having trouble, please contact us at support@sensorpush.com for more assistance.

Connectivity

Does this sensor connect via WiFi and push alerts to my phone when I'm away, or do I have to be at home and connected via Bluetooth

The sensor itself connects via Bluetooth. However, now you can add the SensorPush G1 WiFi Gateway which will relay the data from any in-range sensors to our included cloud service for access from anywhere!

Storage

How much data (time) can the unit store? I'd like to intermittently monitor a wine cellar not near my home.

It holds at least 20 days of data. In a stable environment like a wine cellar, the storage would last even longer because it only stores when data changes, but you can count on a minimum of 20 days.

Alerts

How do I configure alerts?

Alert settings are found on the sensor settings page in the app. To access sensor settings, tap a sensor in the main list and then tap the button in the upper-right corner of the sensor details page.

You'll see two sliders, one for temperature and one for humidity. Each slider has two handles. The area between these two handles is the desired range of conditions. If the "Alert Me" toggle is enabled, you'll be notified whenever conditions leave this zone.

Here are a few examples:

Alert above 110°F

Alert below 32°F

Alert over 110f 68e189adddef9c0e97d8e2e382d079ec56b6010a4dc1850db70be19eb348647e Alert below 32f d1e899fd1c3e1030d68d18686fc18fa1587591a3dfc1e022181623c90d18438a

Alert when humidity is below 40% or above 60%

Alert when temperature is below 65°F or above 75°F and when humidity is below 40% or above 60%

Calibration

Can I calibrate my SensorPush? How?

Yes.

First you will need an accurate reference for temperature and/or humidity. Each value is calibrated separately and you can choose to calibrate one, both or neither as necessary. Accuracy of the uncalibrated sensor can be found in the full specifications.

Calibration is only intended to correct for small variations (typically up to a few degrees or around 5% relative humidity). If you're seeing a bigger discrepancy than that while calibrating, please contact us, as that would indicate that there's a problem with either the calibration process or your sensor. We'll be happy to help sort it out.

With a Reference Device

If you have a trusted thermometer or hygrometer that you know to be very accurate, you can use it as a reference. Simply place it next to the SensorPush in a stable environment, let them sit for at least 30 minutes to acclimate to each other, be sure you have an updated reading and then use the calibration controls (shown below) to adjust the SensorPush to match the reference. The sensor settings page can be accessed by tapping the button in the top right corner of the graph screen.

Temperature

If you don't have a reference device, you can still calibrate your sensor. Ice water makes a great temperature reference. Just mix up a bowl of ice water, with a good even mixture of ice and water. Give it a good stir and let it sit while you seal your SensorPush in a zip-top baggie. Get as much air out of the bag as possible. Place the SensorPush (inside the baggie) into the ice water mixture. It's best to leave the zip top out of the water, just in case it doesn't seal entirely.

Give the SensorPush at least 30 minutes to acclimate, be sure you have an updated reading and then adjust the calibration controls so the value reads exactly 32.0°F (0.0°C)

Humidity

For calibrating humidity, the "salt test" is quite popular, and instructions can be found readily on the Internet. The chemical principle is sound and it can work quite well, but we find it to be difficult to execute consistently and accurately.

Calibrating to an inaccurate reference can be worse than not calibrating at all, so we prefer the Boveda One-Step Hygrometer Calibration Kit, available for less than $10 on Amazon.

Just open the baggie, seal your SensorPush inside and place it at room temperature in a location with minimal temperature variations. Let it sit undisturbed for at least 24-36 hours, be sure you have an updated reading and then adjust the calibration controls to read exactly 75.0% humidity. Keep the calibration kit sealed and you can use it multiple times for at least 3 months after the initial test.

Battery

How long will the battery last?

Typical battery life is 1-2 years; more in warm conditions and less in extreme cold.

Is the battery replaceable?

Yes.

How can I replace the battery?

The battery in your SensorPush sensor will last over a year in typical conditions. When it's time to change it, the process is quick and easy. Just follow these simple instructions.

The easiest way to open the case is with an old credit card or similar plastic card. Hold the sensor with the back facing you (the side with the seam) and with the text upright. Using a corner of the credit card, slide back and forth along the top seam pushing inward until the card penetrates slightly (squeezing the left and right sides of the sensor can help).

Then slide the card along the top edge to the left side and pry outward and the back cover will come off. The circuit board will then come out on its own. It's positioned by two plastic pegs but is only held in by the back cover. The battery is on the back of the board. It's a CR2477 lithium coin cell. The + side of the battery should face away from the circuit board.

Reassembly is the reverse, with one trick: it's easier to replace the back cover if you put the top side in first, as the bottom has two smaller pegs that are designed to snap in more easily.
