How to get weather data?

Question

Programming

Is there a ready solution to get current outdoor temperature data? So far, the simplest thing I’ve come up with is to parse the Gismeteo, Yandex weather site, openweathermap.org with a python script (but this solution may stop working when changing the site design). Ideally, I would like multiple data sources.
It is necessary to control the microclimate in the room, so as not to install outdoor temperature sensors in every house or building, the temperature of the coolant is formed based on the outdoor temperature. Climate controllers are gradually moving online, and temperature sensors sometimes need to be pulled over 100 meters and the place can be unsuccessful ("vandal" or periodically illuminated by the sun to unrealistic readings).
Actually, the question boils down to the fact that perhaps there is a site that gives ready-made data and which does not need to be parsed. And perhaps there is a ready-made solution, a program / script that pulls weather data and presents it in a convenient form.
Something similar has already been discussed here

But the solution has not been published.
