Ozeki Smart Device Server

If you wish to operate a network of smart devices, you need a centeral computer/server to manage them. Ozeki Smart Device Server is exactly this. It allows you to maintain a list of the devices and it makes it easy for you to communicate with them. It can be scaled up very quickly from small device networks to very large device networks. To sum up what Ozeki can do in one sentence: It makes it possible to communicate with devices using messagrs.

Application areas

Control a building, a plant, a city or a country wide network by reading smart meters remotely and controlling them from a centeral location. This system is compatible with many smart electricity, gas, water and other meters.


- Remote readings over SMS
- Remote readings over Internet
- Local readings over LAN
- Local readings using Radio
- Local readings using Modbus
- Local readings using MBus
- Local readings using Serial


- Collect meter readings
- Scheduled meter readings
- On-demand meter readings
- Log meter online/offline status
- Remote error detection
- SMS notifications for customers
- SMS notifications for employees

Application backend

- Save readings into SQL database
- Save readings into text files
- Pass readings using HTTP API
- Example client in C#.Net
- Example client in Java
- Example client in Java

Robots and embedded systems

Robots and smart autonomous devices, such as vacuums cleaners, smart coffee machines contain a small built in PC. In most cases the CPU is ARM based and the built in PC runs Linux. Ozeki can be installed on such embedded Linux systems and it allows the device to communicate with the sensors and actuators.

- MBus electricity meters
- Electricity impulse counters
- Using cameras for electricity meters


- SMS capable gas meters
- Internet capable gas meters
- Modbus / RS485 gas meters
- MBus gas meters
- Impulse counters for gas meters
- Using cameras for gas meters


- SMS capable water meters
- Internet capable water meters

Local communication hub for device networks

Ozeki can be used to control a local network of devices through radio or through a wired communication network. For example if you use radio, you can controll power outlets, window shades, radio controled lighting, garage doors or anything that comes with a radio remote controller. If you think about wired networks, think about ModBus or Ethernet networks, that can be used in Building automation, to control doors, read data from smart electricity meters, or control thermostats.

Device cloud communication server

If you operate a large array of devices, you will want to use the Internet or the mobile network to communicate with them and to control them. In this setup you may install Ozeki into a cloud service (such as Amazon AWS or Microsoft Azure), or you may install it on a Server in your office. In both cases you can login to Ozeki using your webbrowser, and see which devices in the network are on-line and you can exchange messages/files with them.

Voice calls

Ozeki 10 has a built in IVR system, that allows the engineers on the field to make a voice calls to query the status, registration number and other details of smart meters on the field. They can use the DTMF keypad of ther mobile phone to perform various tasks. The built in IVR can be customized to act according to the requirements of the backend application.


The engineers on the field can perform various tasks using SMS messages. SMS messages are a good option for areas, where mobile internet coverage is not available. Engineers can send various commands in SMS, and the system will automatically respond to them.

Smart phone app

Ozeki offers an easy to use chat based smartphone app, that allows your engineers on the field and login to perform various tasks. It uses the same messages, that are available in SMS or through the IVR system. This App can be used when mobile internet coverage is available.
