You can also use the button in the top right corner of the LightBlue app to have it perform the hex to decimal conversion for you. Just select the “4 Byte Signed Int Little Endian” option.

The valid range is 32 – 32767. The value 0xFEEF is a special value that disables advertising altogether, rendering the device unconnectable until the battery is removed and reinstalled. It is used internally for device testing and should not be used under normal circumstances. Lastly, broadcast/reception range is an important consideration whether you use a G1 WiFi Gateway or not with your sensors. We have an article about range thatThe sensor devices communicate via Bluetooth Low Energy, also known as BLE or Bluetooth 4.x. On iOS the system-provided SDK is CoreBluetooth, while on Android, BluetoothGatt can be used. On Linux systems, the nodejs library noble is a good option. Similar libraries are commonly available for other development environments. prolonged exposure to > 80% RH may create an offset of up to +3% in the readings. This effect gradually reverses after return to < 80% RH conditions) We should point out that the Sensorpush isn’t technically a Wi-Fi device. The individual sensors transmit via Bluetooth. We had no problems with data transmission while using it. But, it would be nice to have a true Wi-Fi wireless thermometer for times when we’re away from home. Even at the maximum value of +5dBm, battery life is quite long (over two years depending upon the operation mode and conditions), so this is the value we typically recommend to reduce signal issues. Valid values are: -21, -18, -15, -12, -9, -6, -3, 0, 1, 2, 3, 4, 5 Learn more about changing batteries. Also, if your sensor doesn't respond immediately after changing the battery, here's something you can try.

Client / Master: The device you are using to access the sensor (mobile device, desktop computer, etc)Request a list of gateways. Add the header "Authorization: " using the accesstoken returned in the OAuth Access step. copy to clipboard curl -X POST "https://api.sensorpush.com/api/v1/devices/gateways" -H "accept: application/json" -H "Authorization: " -d @- < curl -X POST "https://api.sensorpush.com/api/v1/devices/gateways" \

Scroll to the bottom of the following screen (this is the screen with the time graph). You should see "Battery Voltage." Open the SensorPush app to the main screen (the main screen says "Devices" at the top) and tap the Add button. This is the same button previously used to add sensors. Now it will present you with a choice to add a sensor or a gateway. Tap the Add Gateway option.Second, the gateway reads the Bluetooth signals from the sensors through its external antenna. The antenna helps improve the signal fidelity, so this range is slightly better than what you would get from a smartphone or tablet communicating directly with a sensor. As you might guess, the gateway also uses the external antenna to communicate with your WiFi router.

Open the app, and from the main "Devices" screen and select the button in the top left to open app settings. Now the phone will form a temporary connection to the gateway. This might take a minute or two. If it takes longer than that, please try restarting the phone and gateway and trying again. If you still cannot connect, let us know and we'll be happy to help. Of course, as much as you care about your home, musical instruments, family heirlooms, art or wine collections and other prized possessions, you don't need yet another chore: continually monitoring their thermometer and hygrometer readings. This is why we created a streamlined interface to configure desired conditions and enable alerts. 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) Whether you are using a SensorPush sensor on its own, or in conjunction with the G1 WiFi Gateway, the initial setup (a.k.a. pairing) process is the same.If you’re curious or interested in perfecting conditions inside your home or office, give one a try. We own neither a boat nor an RV, so this is purely speculative. But it is based on experiences of friends and family. And so, everything from the sensor firmware to the apps themselves has been hand-crafted line by line. We believe the extra effort shows in the end result. The Future
