When a sensor is renamed or alert settings are changed, the updates are reflected on all connected devices within moments. When you add new sensors, just pair them with one device. The gateway and all other devices will automatically import them and begin monitoring right away. The HTP.xw Temperature / Humidity / Barometric Pressure Smart Sensor is perfect for monitoring weather conditions, your home, greenhouses, musical instruments, wine, cigars, art and keepsake collections and much more.

To read data, write any 32-bit value to the characteristic (e.g. 0x01000000). This triggers a sensor read. Once the read is complete (typically less than 100ms later), the data will be available to read, in hundredths of degrees Celsius (e.g. 21.34 degrees C will read 2134). These steps are in accordance with the oAuth2 specifications such that if any of the three tokens are lost, the tokens eventually expire, thus securing the account once again.

About PyPI

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. Identifies the type of sensor and its capabilities. Currently the only available 2nd generation model is the HTP.xw, which is identified by the value 0. This read will also populate the relative humidity data, so if desired, it can be read immediately after without the need for a separate read command. Stability of temperature and humidity over time is often the most important factor to avoid costly and irreparable damage. SensorPush makes it easy to see changes to help determine and take the proper course of action when necessary or rest easy when all is well. SensorPush was created by Cousins & Sears Creative Technologists The 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.

Verify that your WiFi network is using 2.4GHz or is in "dual band" mode (both 2.4GHz and 5GHz). 2.4GHz is the most common type of WiFi, so if you are unsure, you likely already have 2.4GHz. The apps had to be extraordinarily well-designed. They needed to offer insightful ways to view and analyze data, current and past. Once in app settings you'll notice a section called "Configuration" with a switch for Bluetooth access. 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). In the Graph view, sensors are listed and can be toggled on/off by using the switch to the right of the sensor's name. Once toggled on, that sensor's data appears in one of two viewing options: "Layers" or "Streams."SensorPush is the answer. Our Smart Sensors are compact and easy to use. They work with painstakingly designed mobile apps that not only make you love using them, but also require as little use as possible. It takes just a few moments to install our free app and pair your first sensor. After that, it's up to you. Verify that your WiFi router is set to 2.4GHz or "dual band" mode. 2.4GHz is the most common default setting for WiFi routers, so if you haven't changed that specifically, it's likely okay as it is and probably doesn't need adjusted. You should now be able to monitor your sensors over the internet. You can test this by turning the Bluetooth off on your mobile device. Provided all of the sensors are in range to the Gateway, you should be able to see them update in the app roughly once per minute. A small icon shaped like the Gateway will appear to the right of the sensor's name if the sensor is communicating via the Gateway. You can also verify that the information is up to date by looking at the "Last seen" time right beneath the sensor's name on the list of devices in the main screen of the app. readings should be within the last couple of minutes of the current time if the sensor is communicating normally through the Gateway. 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.

Even when you're away, the Smart Sensor will continue to monitor conditions and upon your return the data will be seamlessly pushed to your Android device which will notify you of problematic conditions so you can take action. Wireless Range: 100 meters line of sight under ideal conditions with no obstructions. Because of the way radio signals work, obstructions or interference can reduce the effective range substantially. Every situation is different, but by way of example, one of our test cases is a wood-framed 2,600 square foot, 2-story home. Sensors can be read virtually anywhere in, or immediately outside, the home. This was the moment we really, truly started to care about temperature and relative humidity. We wanted our new baby to be comfortable. And, since he can’t really tell us himself we needed to collect some data. A Simple Digital Thermometer “Works” a Wireless Thermometer / Hygrometer is Better. In the dashboard UI, there are two primary modes (selected in upper left). They are the "Graph" and the "Status" modes. Graph mode is the time series data from sensors. Status mode is the current conditions, the signal strength, the last reading, and other details for your sensors. In this view, red indicates that the sensor's last reading is out of date. This is particularly useful for accounts with large numbers of sensors. You can also connect via Ethernet. Just plug in the Ethernet cable (DHCP is required) and wait for the "Connected via Ethernet" message to appear.Open the app, and from the main "Devices" screen and select the button in the top left to open app settings. 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. If the sensor was working previously, sometimes performing the add sensor process again can effectively "reboot" the sensor and get it working again. If you are able to physically access the sensor, this is a good next step. To do this, you do not need to remove or delete the sensor from the app, as this will delete all of your data and settings. With the sensor within reach, just tap the add device button in the upper right corner of the main screen in the app and select "Add Sensor" and follow the prompts. The authorization token is used to request two additional tokens: access and refresh tokens. The access token authorizes the user to begin using the API. This token is valid for 30 minutes, at which time the client must request a new access token using the refresh token. Once the settings are correct, it's worth rebooting the phone. Modern mobile devices' Bluetooth systems are increasingly complex and under demand from a wide variety of applications, even ones that you don't specifically think of as using Bluetooth. Because of this, it's not uncommon for them to begin to malfunction in unpredictable ways. A reboot helps make sure that the SensorPush app has a known good state to work with and eliminates a variety of variables and possible issues.

Permissions: Read-only (In GATT terms, this field is read/write for internal purposes, however, attempting to write to this field is not allowed and will result in immediate disconnection from the device, so consider it to be read-only)

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. In the screen that appears, tap “Write new value.” Enter the value 01000000 and tap Done. This tells the SensorPush device to read the temperature and update this characteristic with the new temperature value. Their work has supported global brands such as Nike and FedEx. Their data visualization work has been published in mainstream media outlets like The New York Times Magazine and Popular Mechanics. They have been featured at events from TED to the Sundance Film Festival.
