[sendtohttp] Add Open-Meteo events + JSON event

[chromoxdor]

To-do:

• Lots of documentation and examples
• Some more annotation in the code probably

---

As being asked here: https://www.letscontrolit.com/forum/viewtopic.php?p=72083#p72083 i do a PR for Open-Meteo events

1. It parses url for the variable type (current,hourly, daily)
2. Contrains the response and parses this for the variables
3. depending on the variable type it generates an event (e.g. On OpenMeteo#current Do... )

It works but responses can get quite long, especially for hourly variables and also when all types combined together.
But for now it was working fine on an esp32 classic even with very long resonses > 6kb

I tried to kind of create a size check but i am no expert for memory constraint systems. Maybe you can help out here with some recommendations.

I guess when calling this it is already to late 🙂 :

 if (uri.length() > 5000) {
        addLog(LOG_LEVEL_ERROR, F("Response exceeds 5000 characters"));
      }
      else {

How to use:

1. visit https://open-meteo.com/en/docs
2. click together what you need and scroll down to the API Response section where you find this:

3. usesendtohttp api.open-meteo.com,80,/v1/forecast?...

Issues:

1. ESPEasy throws a "Too many arguments" error but it still works fine
2. In the log only 25 eventvalues are displayed. But you can still access all of them with rules. I wonder where the limit is?

Command:
sendtohttp api.open-meteo.com,80,"/v1/forecast?latitude=52.5244&longitude=13.4105&current=temperature_2m,relative_humidity_2m&daily=temperature_2m_max,temperature_2m_min,uv_index_max&timezone=Europe%2FLondon&forecast_days=3"

Response:

2580494: EVENT: OpenMeteo#current=4.3,76
2580503: EVENT: OpenMeteo#daily=7.5,2.4,1.2,1.5,-1.0,-1.1,1.00,0.95,0.70

1. ESPEasy throws a "Too many arguments" error but it still works fine

Wrap the (long) url, that contains several commas, in quotes, and this issue should be resolved 😉
Alternative: url-encode the commas to %2C so ESPEasy doesn't see them as commas

I tried that and it didn't work...but now i think i know what happend. I have this auto correction plugin in my browser. Disabling it helped :)

Thanks for helping me...

[chromoxdor]

I combined the two functions because there is actually no need for that

What needs to be done to get this merged?

What needs to be done to get this merged?

I will have a look at it now...

[TD-er]

Well if you can do a last-minute check to make sure it is still working after these changes, I will merge it when no issues found.
So please let me know if you did a quick test.

[chromoxdor]

Check completed.
Everything seems to work as expected...

[chromoxdor]

Thanks :)
