Introducing TLab IoT Platform

An IoT Platform for Enterprises

Our new multi-purpose, low-code IoT platform that requires no programming skills and minimal time to create custom IoT applications. 's platform not only runs with all major LoRaWAN network servers, it also provides you with templates for the most popular devices.

Next to deep LoRaWAN Integration you can connect your IoT Devices using the following Integrations:


Connect your brokers and subscribe to any topic. Includes payload decoders and downlinks for your MQTT devices.


Send data to your devices on Datacake via webhook. Payload decoders for HTTP requests are also available here.


Using GraphQL API, write metrics or automate the entire platform as well as the deployment of your devices.

Welcome to Τ!

The first community in Greece, dedicated in research and development on state of the art technologies in sectors of IoT, Networks, DevOps and embedded devices


We do have a worldwide coverage IoT network

While people are waiting for 5G connectivity, LoRaWAN Networks like or Helium have worldwide coverage and it's free for anyone to use...

Try our new IoT Plaform for free and Connect Any Device using Any LoRaWAN network!

We have teamed up to bring together people interested in Embedded systems, Hardware and software programming and create IoT related projects.

Connect with us to deploy the first IoT network in Greece! Join former Arduino Meetup and WiFi city-wide Community organizers and all of their members which are embraced here. Share your tech love and experience!
