Hiding data from the display

In this page you will learn how to show/hide specific data from the display of the device. Even though the data is hidden from the display, you still receive it in the keepalive.

Hiding/showing spеcific readings on the display

Measured temperature

SET

Byte index	Hex value – Meaning
0	40 – The command code.
1	00 – Hide the measured temperature; 01 – Show the measured temperature. Default state.

Example downlink: 0x4000 – Hide the measured temperature.

GET

Byte index	Sent request	Received response
0	41 – Command code	41 – Command code
1		00 - The measured temperature is hidden; 01 - The measured temperature is shown.

Example downlink sent by the server: 0x41;

Example command response: 0x4100 – The measured temperature is hidden.

Measured humidity

SET

Byte index	Hex value – Meaning
0	42 – The command code.
1	00 – Hide humidity; 01 – Show humidity. Default state.

Example downlink: 0x4200 – Hide the measured humidity

GET

Byte index	Sent request	Received response
0	43 – Command code	43 – Command code
1		00 - The measured humidity is hidden; 01 - The measured humidity is shown.

Example downlink sent by the server: 0x43;

Example command response: 0x4300 – The humidity is hidden.

Measured light intensity

SET

Byte index	Hex value – Meaning
0	44 – The command code.
1	00 – Hide light intensity; 01 – Show light intensity. Default state.

Example downlink: 0x4400 – Hide the light intensity.

GET

Byte index	Sent request	Received response
0	45 – Command code	45 – Command code
1		00 - The light intensity is hidden; 01 - The light intensity is shown.

Example downlink sent by the server: 0x45;

Example command response: 0x4500 – The light intensity is hidden.

By Default all 3 metrics are displayed at the same time (temperature, humidity, and light intensity).

CO2 related images to be shown on the display

You can set how the CO2 measurement is represented on the display. You can select to either a value and/or an emoji.

SET

Select one of the 2 options for displaying the CO2 level.

Byte index	Bit index	Hex value – Meaning
0	-	82 – The command code.
1	7:3	Reserved.
	1	1 to show the CO2 value on the display with digits. 0 to hide it.
	0	1 to show the CO2 emoji and level on the display. 0 to hide it. Default value in HEX - 03

Example command: 0x8303 – when we separate the command code value we get 0x03. Converting it to binary we get 00000011. Utilizing the last 2 bits we have 11, thus the value will be displayed in digits together with an emoji.

GET

Obtain the currently selected option for displaying the CO2 level.

By default, all 2 options are shown.

Byte index	Bit index	Hex value – Meaning
0	-	83 – The command code.
1	7:3	Reserved.
	1	1 if the CO2 digital value is shown on the display. 0 if hidden.
	0	1 if the CO2 emoji is shown on the display. 0 if hidden.

Example command: 0x8302 – when we separate the command code value we get 0x02. Converting it to binary we get 00000010. Utilizing the last 2 bits we have 10, thus only the CO2 value will be shown on the display.

The Default both metrics are displayed at the same time (CO2 value and CO2 emoji).
