About getting current temperature from forecast.io inside Node Red

[Kyaw Zin Latt]

Hi Guys,

I would like to know how to get just only current temperature from forecast.io using Node Red. How to filter that message coming from https://api.forecast.io to get current temperature. Or any other API that can provide the current temperature e.g. accuweather in mobile devices.

thanks

Kyaw, 

I used the recipe here

https://www.ibm.com/developerworks/community/blogs/B-Fool/entry/weather_prediction_with_node_red_forecast_io_and_a_raspberry_pi?lang=en

as a start for building weather services.

thanks

Ed

I've also been using  http://openweathermap.org/api

with some success - don't poll too quickly...

returns nicely formatted json which is easy to pick apart... msg.payload.main.temp  etc

(noting that they use K - so subtract 273.15 for C)

I've just added my weather flow to nodered.org which parses very accurate, calibrated data from NOAA, which is the weather data coordinating organisation for every airport worldwide. If you live anywhere near an airport, just substitute it's ICAO airport code in the function node, and the flow should just run as is.

Even if you don't use this flow, it may help you develop a flow for forecast.io

Many thanks to you all.

It is working fine now.
