I installed openweathermap and the dashboard for node-red, But the gauge display 0.
I want to display the current temperature from openweathermap with the dashboard-gauge.
I need to use the following objects from openweathermap: tempc, tempk, humidity, windspeed ...
Here's a flow one of my students created.
You will need to adjust some of the JavaScript (in the function block) to filter out the objects YOU need.

I've expanded the openweather function as shown.
var msg1 = { payload:msg.payload.temp_maxc * (9/5)+32};
var msg2 = { payload:msg.payload.tempc * (9/5)+32 };
var msg3 = { payload:msg.payload.temp_minc * (9/5)+32 };
var msg4 = { payload:msg.payload.description};
var msg5 = { payload:msg.payload.icon};
var msg6 = { payload:msg.payload.windspeed};
var msg7 = { payload:msg.payload.winddirection};
var msg8 = {
"payload": {
"windspeed":msg6,
"speed_unit":"MPH",
"winddirection":msg7
}
}
return [ msg1, msg2, msg3, msg4, msg5, msg6, msg7, msg8];
This will flow into an template as follows:
@import url(https://fonts.googleapis.com/css?family=Dosis:200,400,500,600); .compass_container{ transition: 1s ease-in-out; position: relative; display: none; width: 500px; height: 500px; border-radius: 100%; font-family: 'Dosis'; font-size: 80px; box-shadow: inset 0px 0px 0px 30px #777; background-color: {{color}}; } .compass_container .compass_header{ font-weight: bold; position: absolute; text-align: center; width: 100%; font-size: 75%; top: -15px } .compass_container .text_container{ height: 100%; width: 100%; padding: 0px; display: block; border-radius: 100%; display: flex; flex-direction: column; justify-content: center; align-items: center; } .compass_container .arrow{ transition: 1s ease-in-out; width: 100%; height: 100%; display: block; position: absolute; top: 0; } .compass_container .arrow .triangle{ width: 0; height: 0; border-left: 45px solid transparent; border-right: 45px solid transparent; border-bottom: 90px solid black; position: absolute; top: -15px; left: 50%; margin-left: -45px; z-index: 99; }N
<div class="nr-dashboard-text text_container">
<div class="direction" style="font-size: 120%">{{direction}}</div>
<div style="flex-direction: row; font-weight: bold;">
<span style="font-size: 100%">{{msg.payload.windspeed}}</span>
<span style="font-size: 75%">{{msg.payload.speed_unit}}</span>
</div>
</div>
<div class="arrow" style="transform: rotate({{msg.payload.winddegrees}}deg);">
<div class="triangle"></div>
</div>
the output of the template through the debugger is:
3/13/2019, 2:34:17 PMnode: 3d099477.7516ec
msg.payload : Object
object
speed: 35
speed_unit: "MPH"
degrees: 142
My problem is that my output from openweather does not display anything thru template.
Can you help?
THis is a very cool way to show temp and wind direction.
Could you please provide your whole flow by "menu (top right corner) -> export -> clipboard"?

Issue solved. - thanks
Thanks dynamicdave for sharing this!
I've just started playing with node-red on the Raspberry pi.
I've been struggling how to pull the one piece of data from my OpenWeather feed.
Thanks, very useful to an amateur node-redder like myself!
