# MClimate HT Display lite

## General Information

MClimate HT Display lite LoRaWAN is a stand-alone HT sensor powered entirely by solar energy using an organic solar panel. The device features a 1.54" e-ink screen, temperature, humidity and LUX sensor. The user can see the current levels of temperature, humidity and light intensity, as well as a historical trend. The device sends an uplink periodically, or when the "Check" button is pressed. The data from the HT Display can be used in any LoRaWAN-compatible system, incl. Building Management Systems to control demand-based ventilation. Sensor information can be exposed as datapoints in Modbus, BACnet and KNX systems through the use of a special gateway.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.mclimate.eu/mclimate-lorawan-devices/devices/mclimate-ht-display-lite.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
