What is a Cloud Dialler?

A cloud dialler uses a server in a data centre to send SMS message and make telephone calls. The main advantage of using a cloud dialler over a traditional dialler is the ability for the system to communicate even when there is a problem with the dialler or your account. For example, if your traditional SIM based dialler runs out of SMS or call credit, it is no longer able to tell you. If the signal is too low it can’t tell you. If it disappears from the network it can’t tell you. A cloud dialler can as it’s the computers in a data centre that do the communication and they’re able to discover any potential faults.

Other useful features of a cloud dialler include

  • Can read out your alarm message in a call
  • Can make all calls and send all message at once
  • Easily programmed using a PC or Smart Phone

 

We offer both WiFi and GSM diallers on our website here

IoT Product Development

We have a number of web-enabled product that we have developed ourselves or for third party companies. We have quite a wide range of code that we can re-use in development of your products in order to rapidly assist you on getting your products connected. This can significantly reduce the cost and lead time on product development.

How it works

Our IoT PCBs connect to our servers permanently. We use a proper IoT SIM which can use any network and is expected to maintain a data connection. They don’t send SMS messages or make calls however. Our servers have to do this so we use an Amazon Web Services Cloud server for reliability. If the PCB can’t connect it will retry every 2-4 minutes. Standard SIMs are not reliable.

The PCBs upload a data string with input data either on a timer or when prompted by something external. We have standard strings with voltages, signal strength, output settings etc… We also have some customised strings that the server recognises for various products. Some of these products are ours and some are for other companies we have developed products for.

The PCB server puts these strings in a file in a folder on the web-server so they can be accessed by a browser. They are normally stored as a php file so you have to be logged in to open them or a txt file if it doesn’t matter.

The web-pages will have a JavaScript section that reads these files and fills in the data on the page.

The above unit sends a string that the server knows to store as pmData.php in the individual unit’s own folder. The web-page keeps reading this page every second and updates the dials and charts with new data. There is a time stamp on this data so it knows if the data stops coming.

Turning to the PCB, we have common firmware across our products. 7.01 is the current GSM only firmware 7.05 is the combined WiFi and GSM firmware. We have an area in the code just for each product’s specific needs. We have firmware for I2C pressure, humidity and temperature sensors. We have SPI RAM storage and SPI sensors. We can read-in UART, RS-232 and RS485 data.

All of the sensor or UART/RS232 data can be sent directly to the web-page files as described above or stored in a log file. Additionally, we can read that data on the chip and look for specific words and raise events.

An event is used to trigger an email or SMS (or even call). For example, if an input voltage goes over a certain voltage it can create an event thus triggering a message. Similarly, if a certain string of characters are read in through the UART input then this can trigger an event to send a message.

We can also send data in reverse from a web-page. For example, you can change something on a Raspberry Pi through the UART command line interface via a remote web-page.

Our chips can be flashed remotely.

Current firmware versions 02/09/2019

The current security product firmware version by product are as follows:

C5S v7.01R29

Honeywell ADE v7.01R28

If you don’t want your device to use data you should make sure it’s up to date and then send:

web disable

If you want emails to work, you should send:

web enable

If your unit is out of date please get in touch with the number and network for an update.
