is there a weather binding out there where I don’t have to create a Weather Account?
Dark Sky, Weather Underground, Weather Binding, Ambient Weather, Weather Company Binding need a Bridge with a API Key. To get the API Key you have to create a Account at every Weather Websites.
Will give you a three day forecast, no binding needed, just make sure that you are not refreshing too frequently, otherwise this (and similar sides) will block you. An hourly update suffices for me and does not create any problems.
Besides this might be a trend in some places, it just makes technically sense sometimes.
I would make that mandatory too for such a service.
If i would ran a hardware which provides an api like this, i would like to know who is doing the requests, to have some influences, if one does cause problems for the other users with an inappropriate amount of requests for example.
Keep a track of your accounts and read the t&cs.
Also use a separate email for different types of accounts. I have one for HA. One for Chinese sites, etc…
