How to get weather on esp using API with key?

String operations are still very preliminary.
Typically those can only be used to send to somewhere, like formatting an URL in rules, writing to a display, used in MQTT topics, logs, email.
You cannot store them in a dummy task, or in a variable.
The only 'dynamic' use with strings is as an eventvalue to hand them over when generating and handling an event.

OK. Thanks. I've already figured it out from the forum posts.

Сan add this "%c_dew_th%" to documentation here https://www.letscontrolit.com/wiki/inde ... asyFormula , for the formula for calculating the dew point temperature

Do not use the wiki as that's completely outdated.

Use the Read-the-docs instead: https://espeasy.readthedocs.io/en/latest/

Also all variables are available (including their current values) on the system variables page (see tools page)

The wiki is very outdated. What you're looking for is documented here

Thanks. I found it difficult to find it, perhaps because of the translation difficulties(

Is it possible to add support for the ST7796 display? Esp32 30pin, "easyesp display" + parser would be perfect, there is already ST7796

Not sure if I understand your question completely.
This Weather API feature is available in the MAX builds by default, and can be enabled for Custom builds. The documentation for how to create a Custom build of ESPEasy is here.
MAX builds include all plugins, and 99.9% of available features, but are only available for ESP32 units with 8MB or 16MB Flash memory.
