# Device Overview

### Introduction

* The Yobiiq iQ Opentherm device is a ready-to-use radio transmitter for transparently sending/receiving opentherm communication.
* The device issues data periodically, alarms (absence of mains power, button operations) are send immediately after occurence.
* The LoRaWAN join procedure can be re-initiated by a push button.
* The user can access the configuration remotely and send opentherm communication via the LoRaWAN downlinks.
* The iQ Opentherm device requires a 24VDC power supply.
* The iQ Opentherm device is compatible with the IQ Platform and Application.

🛠 The iQ Opentherm device is delivered by default with the OTAA join procedure so the user can connect the device to a LoRaWAN operator of choice.

### Features

Below is a list of the most common features, for more details check the operational overview.

* **Opentherm transparent:** the iQ Opentherm by default is a transparent gateway for Opentherm, it forwards data between the boiler and thermostat, if configured the iQ Opentherm can actively modify setpoints and operations from the boiler.
* **Class C**: The device operates in Class C based on LoRaWAN Protocol version 1.0.4.
* **External Power**: The device is requires an external power supply
* **Temperature Sensor**: The device has a built-in temperature / rv sensor.
* **Reset Button:** A button to reset any alarms and (re)join a LoRaWAN network.
* **LED Status**: LED indication for Power, LoRaWAN Network Status and Opentherm TX/RX.
* **Relay / 0-10V:** the iQ Opentherm optionally comes with a relay and 0-10v input to interface with a Building Management System.
