5.3.1 Configure Data Source

This section introduces the data source selection for this device.

Introduction

It is necessary for the thermostat to know the ambient temperature and humidity to display on the screen and achieve the accurate control. The thermostat supports the following data sources:

Embedded (Default): Use thermostat internal temperature and humidity sensors.
LoRa: Receive temperature and humidity data from LoRaWAN^® network server.
D2D: Receive temperature and humidity data from Milesight sensors via Milesight D2D transmission.

When to change the data source

By default, the thermostat uses internal temperature and humidity sensors that suits most applications. However, if one of the following scenarios occurs, you may choose to use other data sources:

The accuracy of the internal sensors does not match the requirement;
There are unavoidable temperature influences at target installation location of the thermostat;
The target installation location of the thermostat is not representative.

Configure by Downlink

Select the data source.
- JSON Command: temperature_source_config, temperature_humidity_source
- BACnet: Temperature Humidity Source
- Raw Hex Command: Data Source + Timeout, Data Source
Configure the data source details.
If the data source is LoRa, send commands from LNS.
- JSON Command: temperature, humidity
- Raw Hex Command: Temperature, Humidity
If the data source is D2D, enable D2D Data Receiving Settings and configure the related parameters.
(Optional) Configure the offline mode if the data source is LoRa or D2D. By default, the thermostat will keep the current control status if it does not receive temperature data for preset timeout (10 minutes by default).
- JSON Command: offline_control_mode
- Raw Hex Command: Offline Control Mode
