hello i have a idea in mind but can't find out where to start. i have this data https://app-prod-ws.meteoswiss-app.ch/v1/stationOverview?station=WYN in a fist step i just wish to put them out in the msg.payload nice splited out time, temperature, windDirection, windGust and so one the other pa…

You don't tell us what you are doing to get the payload. here is an example of retrieving the payload as an object rather than a string, and how to move the WYN object to msg.payload. [{"id":"932ab456.59e2b","type":"inject","z":"8d22ae29.7df6d","name":"","props":[{"p":"payload"},{"p":"topic","vt":…

@E1cid this helped to get a start. i need a timer to trigger it. And now will have to find out how to split the output to save the Air-Temperature and to find out the math to get Date/time of 1607172334543

Quickly built this for you. It uses the 'node-red-contrib-moment' node to manipulate the epoch value. [Screen Shot 12-05-20 at 01.11 PM] [{"id":"932ab456.59e2b","type":"inject","z":"1e0fcc6f.6695dc","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false…

The moment node really is heavyweight for something that may be simple. (and indeed is already built into jsonata in the change node ) - so no need to install it twice.

Thanks Dave for the 'heads-up' on that.

@dynamicdave this did help - and give a nice base to play around! did try to use the function to get to information at on, did not work in a first step but read and copy other example

Just had a bit of spare time to redo the flow with a Change node with jsonata Date/Time function. I've removed the Moment node as per comments/suggestion by @dceejay [Screen Shot 12-07-20 at 08.54 AM] [{"id":"932ab456.59e2b","type":"inject","z":"d32bc828.464fe","name":"","props":[{"p":"payload"}…

@dynamicdave Thank you very much for your help doing the first steps - is not easy - but the scirpt and import like this helps a lot Thank you. But with testing other question comme up. Like i take the information from a weatherstation, which is close to a river (so it is a bit warmer 1-2C). t…

Storing the values in a database is a good idea as you can extract the data in different ways and display nice graphs and charts. Personally, I would store the readings separately and do the 'maths' on the way out (post-processing) so you could do all sorts of comparisons. I'm not familar InfluxDB …

You can set a time trigger in the inject node

For date and time you can use a function node or change node. Or install the moment node.

I see no air temp but to access any value you would use msg.payload.temperature or msg.payload.windSpeed If WYN object moved, or if not moved msg.payload.WYN.temperature
