Please (please) excuse my ignorance and brevity. I'm trying to decide between Node Red, Home Assistant and RPi Python. I used to machine code in the early 1980s but now in my middle 50s,coding is not so easy. But I am aware of flowcharting and logic, etc. I am going to do a range of mini projects to be combined into a larger whole. My first project is to take projected weather temps over the next 5 days rolling and charting the trend. That weather data could be from an external Web source (in the correct format) or by a personal weather station or by manual input. Can Node Red take in external data, calculate and make IF conditions? Thank you for your kind attention and time to reply - I really do appreciate your help. Thanks Kevin E2a Sorry, I forgot - Can I take a library of python code and make a bespoke node? (I'm guessing I can)

[image] afelix: I thought you can only get one at all. The two main retailers in the UK NEVER implemented the Foundations stated policy and only restricted PiZero/W purchases to one per order. And even at one time at a fair, I bought two in the same transaction once - but that have may have been because of my notoriety and they wanted to mix up it with a bad boy :slight_smile:

Here's a link to a very simple weather report I used with the students on my IoT Club. [image] Weather reports from around the world Share Your Projects I had a couple of new students join my IoT Computer Club a couple of weeks ago and gave them this simple exercise to obtain weather reports from around the world. Here's the link to the PDF tutorial guide.

[image] KevinH67: Can Node Red take in external data, calculate and make IF conditions? It is one of the many tricks Node-RED is very good at. Node-red is very good at glueing different/similar sources together and providing the logic to manipulate the data and sending it off to another destination (or visualisation)

And here's a link to a solar powered weather station - bit more advanced. [image] Solar-powered weather station Share Your Projects One of the students in my IoT Computer Club (here in the UK) is working on a personal project to design and build a solar-powered weather station (that will be located in one of the school's gardens) to monitor and report air temperature, humidity and pressure. Here are the Objectives and list of items. The student has split the project into six manageable stages. Using a solar panel to charge a Li-Ion battery and power a Wemos D1 Mini. Putting the Wemos D1 Mini into 'deepsleep' to conserve …

Thank you enormously, Dave and bakman2 Sometimes it's hard to express gratitude for amazing help. I'll be having a great evening reading up! I'm very happy to give encouragement for the write up. Please tell me where to contribute. Many thanks.

Thanks. I've only used OpenWeatherMap to get current weather conditions. I'm sure it probably does a 5-day forecast as you mentioned in your original question. A couple of my students have been working on an extension to the original flow where the information is placed on the Node-RED dashboard with a photo of the place you have selected using the dashboard buttons. Here's a screen-shot of the dashboard, Node-RED flow and the graphical wiring diagram.

I'm out with the dogs just now without my reading glasses but I can just make out your very kind offer - yes, please with a cherry and sugar sprinkles on top! If I can reciprocate, please do say. I'll read fully when I'm back indoors. Thank you!

Hi Dave and bakman2, I'm new here and only just seen the hearts - you deserve more. I'm told my RPi Zero WH will be in stock early next month. I'll be getting a bunch of sensors also. Exciting times! With massive thanks to you, I'm going to spend my while learning Node Red. Anyway I can help you, please say.

You might want to watch this full playlist, it will cover all aspects of node-red and its' use for practical applications.

Thanks. I'll get to it now :wink: I wish it was possible to award for more than 1 solution.

In answer to your first question - which platform to use - it does not have to be an either or thing - Home Assistant has some very nice prebuilt Lovelace templates that people have put together for Weather reporting, or you can build your own from NR. When you combine the power of NR and Home Assistant you can get some very nice results. However for an absolute newbie then starting with NR is probably easiest and the most gratifying and later as you add more components to manage you may wish to try integrating Home Assistant. Craig
