About the Palamoa Cloud

The Querx network sensors feature a web interface that allows users to access data very easily. It is not generally required to connect the sensors to a cloud service on the web.

Certain conditions that are not always easily established or preexisting are required to access the sensors’ data via the internet, when one is not connected to the local network. Some keywords are static IP-address, dynamic DNS, VPN, NAT and port forwarding.

Many clients would also like to be able to view the data measured by multiple sensors that are located in different places on a single web site.

A cloud offers an alternative that can be configured easily. Querx will periodically send its tracked data to a web server that saves and visualizes the data. Querx has already supported some cloud services, such as Xively, ThingSpeak and dweet.io for a while. Unfortunately, we have had problems with cloud operators changing their service or closing it down entirely in the past. The sale of Xively to Google and displaying data from dweet.io via Freeboard are examples of such issues. Beginning with firmware version 4.2, we have taken a more open approach to cloud integration, supporting the transfer of data to external cloud services that are not directly implemented in the firmware.

Additionally, we envisage a free, independent cloud service provided by egnite. This service is now available and goes by the name Palamoa. The current version is still in its infancy, but already indicates the direction we are headed in. One main focus is customizability without making the configuration too complicated.

The following tutorial is intended to demonstrate that only a few minutes are required to connect Querx network sensors to the Palamoa cloud.

Tutorial: Palamoa Cloud

This tutorial demonstrates how to connect Querx WLAN TH to the service. In general, however, any Querx network sensor can be used with Palamoa. The only differences are to be found in the configuration of the individual sensors. The device should ideally be updated to the current firmware, but at least needs to be running version 4.2.12.

Querx sensors require an active internet connection, in order to transfer their data to the cloud. Should you not be sure whether this connection is operable, please read the first two sections of the tutorial E-Mail.

The current version of Palamoa can already save transmitted data. It is, however, not yet possible to retrieve the stored data. As of now, Palamoa is only able to display the latest data it has received. The web interface is not always updated correctly. Therefore, it is sometimes necessary to refresh the page.

Configuring the Device

 

After creating an account you will see the blank dashboard.

Click the button Add Device, in order to configure a new device.

Tutorial: Cloud Palamoa 2

The header will display a new device without a name or sensor.

Click Unnamed Device.

Tutorial: Cloud Palamoa 3

An input field that lets you configure the device opens.

Enter a name for the device.

Tutorial: Cloud Palamoa 4

Click the tab API-Key in order to receive the key for the device.

Copy the URL with the key into your cache.

Tutorial: Cloud Palamoa 5

Open the Querx web interface in a new browser window and navigate to the page Configuration / HTTP Push.

Copy the URL from the cache into the corresponding input field. Be sure to enter the URL without the initial http://. Fill in the other input fields as displayed in the screenshot and click Save.

Querx will now send a set of data to Palamoa once per minute.

Configuring sensors

 

Back to Palamoa: A first set of data sent by Querx should appear in the dark field after one minute.

Once the data is displayed, click Add Sensor, in order to enter a sensor.

Type the sensor’s name into the input field.

Palamoa is highly flexible, making it able to read various data formats. We need to tell the cloud where the corresponding data is located within the data set. We do this by clicking on the input field Value, thus activating it. We then need to click the temperature value within the data set.

Repeat this procedure for the unit by clicking the input field Unit and then selecting °C in the data set.

Palamoa now knows where to find the data that is required to display the temperature.

When configuring a Querx TH or THP sensor, you can add further sensors.

Click the green bar once all sensors are configured, thus closing the dialog box.

Tutorial: Cloud Palamoa 8

Back on the dashboard, the device appears with the configured sensors.

In the current version it might be necessary to refresh the page for the changes to be displayed correctly.

Tutorial: Cloud Palamoa 9

Pull a text widget from the left border into the dashboard area with your cursor.

Tutorial: Cloud Palamoa 10

Connect the widget and the sensor.

Use your cursor to pull the device’s sensor onto the widget.

Tutorial: Cloud Palamoa 11

The device’s name, along with the sensor’s name and the most recent value appears in the widget. Congratulations, you have configured your first Palamoa dashboard.


 

Tutorial: Cloud Palamoa 12

You can now add further devices, sensors and widgets in the same way, in order to further extend your dashboard.
