OverviewAdd units and/or an emoji icon to displayed data to provide context in a Tiles dashboard. This operation utilizes real-time expressions (more info). The concatenate operator, &, as well as a string denoted by " " are used to add the desired text to the displayed data.
*Real-time expressions are available in the Personal and Pro tiers.
Syntax=[signal] & "text"
In the example above, a temperature stream is providing numerical data (e.g. 73). To add units to the displayed data in tiles, apply the expression, =[signal] & "°F". The data stream above is named, Frontdoor Multi(temperature_F). The expression used is
=[Frontdoor Multi(temperature_F)] & "°F"
In order to add an emoji icon to the display:
- Find the desired emoji at http://getemoji.com. For the thermometer emoji -> http://emojipedia.org/thermometer/.
- Copy the emoji to the clipboard. This will copy the unicode version of the emoji.
- Paste the emoji inside the double quotes " " in the expression.
(e.g. " °F").
Units and emojis can be appended to a numerical data stream and still be viewed as a line graph as shown above. However, prepending text before the numerical value will prevent a line graph from drawing.
Context can be added to door sensors using this same approach (door emoji -> http://emojipedia.org/door/).
Context can be added to motion sensors using this same approach (baby emoji -> http://emojipedia.org/baby-type-3/).
