How to use APIs with Node-RED: OpenWeatherMap Example

One very common use of Node-RED is to use application programming interfaces or “APIs” to move data between devices and/or services that would otherwise be totally disconnected.

To help you get started using APIs with Node-RED if you’re unfamiliar with these tools, we’ve just made a new video about how to build a simple API flow using an example web service for daily weather data.

This data is used to do some basic control on a groov RIO (although the steps are the same on any device running Node-RED, including groov EPIC). Watch the full video tutorial.

All Opto 22 products are designed, manufactured, and supported in the U.S.A. from our Temecula, California headquarters and factory.

Thank you! Really a nice and informative video to get started with node red/json.

Great tutorial. I just started learning Node-RED and this was a great tutorial for my use case. I have some APIs at work for which I'm going to use a Raspberry Pi and Node-RED to display a status dashboard. This was very timely for me.

Super vidéo explicative, merci pour les astuces que je ne connaissais pas

Thanks for these tutorials - splitting out the api info is useful to know

Awesome content, really useful. I am working with esp32's so for me it would probably be node-red to esp32 via mqtt or have node-red post to esp32 http client. Still learning this web/network stuff.

Lots of useful information, thanks! I had used a node from OpenWeatherMap, which was simple, but not as flexible as the http request. I had to convert units with additional nodes.

What a great content, its really helpful for my IOT project. Thank you for create such a good video to us.

I like the explanation. For me would be interesting to verify the cloud/Rain for the next days t o control the heatpump.

I really appreciate the beginner level stuff.
I'm only 28, with a mechanical engineering degree, I work on embedded devices all day, and pretty dang good with logical programming, but all the JavaScript, API, and IoT stuff is totally alien to me!

many thanks great video really well explained.

I've been muddling through with Node Red for years but learned so much from this brilliant tutorial - thank you. I came here because I am trying to use a panasonic-comfort-cloud node. The iPhone app can seemingly check the a/c unit as often as it wants but my NodeRed flow keeps getting 'Too Many Requests' errors. Even though it's set to inject once every hour. I can't find any documentation for the API but I've read that supplying a 'User Agent' might help. Any ideas?

Hi.can you help me please how can l do machine classification for hart signals using nod red l already did the classification in R code

[higiniofuentes]

WOW moment watching the video!
I'm not interested in IoT or Groove, but this video is very useful to programming.
I wonder if Node-Red can generate JavaScript code from the flow created to use it as regular component of a website ? Thank you!

[Starlink]

Hi, could you please give me advise? I did everything as you showed us, but when I clicked inject, I got response: “ Self Signed Certificate in chain”. Any advice will be helpful 🙏🏻.

Thank you for your videos 🎉
