Aruba & DEUTA Controls Sensor data via
EnOcean wireless technology with Wi-Fi access points from Aruba
Whenever you are already using WLAN components from the manufacturer Aruba, such as In hotels or public buildings, you can now upgrade an EnOcean network by retrofitting / connecting an EnOcean USB stick to the USB port of the access point.
Connect the EnOcean USB stick to the Aruba AP
Simply retrofit the Aruba access point on the USB port of the device (on the upper side of the device) with an EnOcean USB stick (our item no. 11227). No further hardware changes are required.
Set up Aruba AP
It only takes a few steps to set up on the Aruba AP. All you have to do is to add the IoT service and the IP address of our control system as the destination for the received EnOcean data, e.g. the VL-700 BASE.
Evaluate data with our system and / or send it to the cloud
Our ECS application on the VL-700 BASE now makes it possible to first enter the characteristics of the EnOcean sensors via a simple dialog (EnOcean ID + EEP).
The data is then already available for building automation and transmission to the cloud.
Mixed operation with the EnoDisc
For our controls like the VL-700 BASE, it doesn’t matter whether the EnOcean data comes from an Aruba Accesspoint or an EnoDisc. The evaluation is identical. Any combination of system is possible, depending on the application.
The application of ECS – explained in detail
Sensors based on EnOcean are generally energy self-sufficient and provide you with data and measured values from your environment in a resource-saving and environmentally friendly way. The sensors generate the energy required to send the data from light, heat or kinetic energy.
The multitude of different sensors deliver your data according to device profiles, the so-called EEP’s (EnOcean Equipment Profiles).
These data are received via aruba access points with USB sticks or EnoDiscs and are initially available on the Ethernet in the form of what is known as ESP3 (EnOcean Serial Protocols Version 3).
These data cannot be used for an application without precise knowledge of the respective EEP and the meaning of the individual data bytes.
On the basis of the DBA (DEUTA driver for Building Automation), however, you can convert the data into already interpreted and scaled values by specifying the EnOcean ID and EEP in plain text, such as Temperature [° C], rel. Air humidity [%] or illuminance [lx].
In the following we present our standard application, the ECS.
The current version of the ECS allows you to send sensor data to the cloud using simple entries in the user interface using a predefined JSON string via MQTT.
We can adapt the format and content of the string to your requirements in almost any way you want. Just get in touch with us.
The user interface of the current version offers the following essential functions:
- Setting of the assigned EnoDiscs (0..31), such as IP address and name
- Setting of the sensors (0..499): EnOcean ID, EEP, trigger mask, name
- Backup of the settings, locally or on a USB stick
- Graphic demo evaluations for certain sensors
- Display of the last generated JSON string to support system integration
EnoDisc Setup Page (not required with Aruba Access Point)
When you call up the page you will see the entries for up to 8 EnoDiscs. You can access the entries for all others using the arrow keys on the lower left edge of the screen.
To change the IP address and name, press the “EDIT” button in the respective line on the right-hand side of the screen.
Enter the IP address of the EnoDisc using the on-screen keyboard and confirm.
If the EnoDisc can be reached and is delivering data, the indicator light to the right of the IP address appears green, otherwise red.
Sensor Setup Page
When you call up the page, you will see the entries for up to 8 EnOcean sensors. You can access the entries for all others using the arrow keys on the lower left edge of the screen.
To change the name, EnOcean ID, EEP and trigger mask, press the “EDIT” button on the right edge of the screen in the respective line.
First enter the EnOcean ID of the sensor in the associated field using the screen keyboard.
Enter the associated EEP in plain text in the “EEP” field.
Is the EEP e.g. D2-14-41, please enter “D21441” without a hyphen and confirm.
In the future, you can enter the bit mask in the “JSON Trigger mask” field to determine the data change when a message is to be transmitted to the cloud. A 1 at the respective bit position of the 4 data bytes leads to data transmission.
The “Friendly Name” is the name of the sensor, which is also sent to the cloud in the JSON string.
JSON string to the cloud
On the start page you can display the last transmitted JSON string.
Application example / DEMO evaluation
On the VL-700 BASE 1 or one of the control units from the VL-SMART or VL-STYLE series, in addition to the actual ECS, you can of course also integrate other functions into the application or have them integrated by us.
In the ECS, for example, we have a page for the evaluation of a multi-sensor STM550 angleget, which visualizes the user data and also graphically shows the values of temperature and humidity in the form of two trends.
Choosing the cloud
In JMobile, depending on the project, you can make the settings for data transfer with the cloud. The screenshot shows the area for MQTT. Overall, JMobile offers the following cloud solutions to choose from:
- Generic MQTT Broker
- Microsoft Azure
- Amazon AWS
- IBM Cloud
Devices and accessories
The above example shows the current version of the ECS. Basically, we can adapt this version exactly to your project requirements on the basis of JMobile. Compared to other solutions, you have at least the following advantages:
Two-stage solution, consisting of EnoDisc as receiving and transmitting unit (Ethernet, PoE) and central computer for cloud coupling via GSM / LTE / LAN
Intelligent evaluation of the ESP3 data according to EEP (EnOcean Equipment Profile) by the DBA
Local provision of all EnOcean data for the integration and connection of the building automation, such as Individual room control
Almost any scalable solution (evaluation of up to 500 sensors on up to 32 EnoDiscs per DBA instance, e.g. a VL-700 BASE 1 or a VL-7xx STYLE)
