The LTE rele5–DINW is designed to be mounted on a DIN rail into a switchboard. LTE rele5 can control two independent electrical circuits in a building e.g. circuit of an accumulator stove and circuit for garage gate control. LTE rele5 uses GSM network and WiFi network. If both connections are available, then WiFi is preferred. The control is made via SMS messages or by ringing. After installation into an electrical box insert a SIM card of any GSM operator and the device is ready to operate.

LTE rele5 has 2 galvanically isolated logical outputs with a semiconductor switch, which can control directly low power circuits up to 230 VAC/90 mA. It’s possible to directly control e.g. a thermoregulator circuit of a gas boiler or a coil of one phase contactor 230 VAC. The contact of this contactor can control either one phase high power appliance (e.g. electrical radiator) or a coil of three phase contactor of an accumulation stove.

LTE rele5 has also 2 analog inputs for temperature measuring and 2 logical inputsLTE rele5 has built in automatic regulator which uses analog inputs from temperature sensors to maintain preset temperature. The temperature on sensors can be readout via SMS. There is an internal built in Li-Ion accumulator which enables to send an SMS in case of a power failure and to restore the output status after a power failure. It’s also possible to monitor the status of inputs and temperatures via SMS during 230 V power failure.


  • Houses, bungalows – remote control of heating, water heating, air conditioning, gate opening
  • Event SMS – e.g. 230 VAC failure, doors or Windows are opened, signal from the alarm unit
  • temperature regulation – automatically switch ON / OFF the connected heating unit
  •  Watching the temperature drop under the limit – the temperature is measured by temperature sensor
  •  Record of entrance and exit cars from parking place or garage (up to 200 users)
  •  Reset for servers and control systems
  • Swith ON / OFF  for boiler, radiator, air conditio
  • Time schedule – creating actions according to the time schedule CRON. Periodical sending SMS or GPRS information about the state to the mobile phone or to Google chart in Internet

Setup and monitoring (configuration and monitoring sw)

The program SeaConfigurator is used for configuration. This software for PC provides connection either using USB cable or remotely using GPRS. The software is free to download and without any restrictions.

Controlling from your phone

Android and iOS applications

For the functionality of the CML application, it is necessary to have an activated data tariff on the SIM card, which is inserted in the device. Transferred data can be charged by the operator according to the tariff agreed by you.



To simplify and conveniently manage your devices from a range of GSM applications, we have developed an application for Android smartphones and iOS (Apple). This application is free of charge.

This app only serves to simplify control. It is not a condition for control. If you do not have an Android phone, you can control the device via SMS or ringing.

You can download this application from  Google Play or Apple Store for free, type into search „CML SEA“. After installing the application, make the first registration, take a photo of the QR code of the device into the “paring code”. The QR code you find in the LTE relepackage.



On-line Data on a website

You can monitor the measured values, including the history, and display them clearly on the website. You can also control the outputs or set up e-mails with alarm messages directly from the website.



Analog measured values, input / output changes and SMS messages are regularly stored in the device according to the configuration settings. Data can be downloaded from LTE-R5-DIN via GPRS connection.
