My understanding is that Metno supports this, but only if you keep the original integration setup when you first start home assistant.
what do you mean? isn’t this the original one??
What I mean is that the very first time you start your home assistant server it sets up Met.no integration to use whatever is used for the latitude and longitude in home assistant. So you could use this for an RV for example, where the whole system moves, but not a single device.
If you manually add this integration later, this is not possible currently.
Is this still not possible?
I’d be fine using the restful and template sensor approach, but darksky is no more. Anyone have a current workaround?
You could use a template weather setup together with a REST interface to get some info elsewhere.
Unfortunately, without a good example of a specific weather provider this is beyond me (or at least beyond the amount of time/effort I’m willing to give it). Wunderground is my preferred source (I’ve found it to be the most accurate, at least for my home). Here’s a sample of the API response in case someone is bored and wants to put it together for me.

The same goes for me. I don’t have the time needed to figure this out. But with a little knowledge of HA you should be able to get this working within an hour. Just use the REST sensor to get the results from WeatherUnderground and then use the developer tools to get the JSON from there. If this succeeds you can copy the templates to the Weather configuration.
