Weather Underground gives a free API key to anyone whose station uploads to it. Once your WU upload is running, get the key at wunderground.com → My Profile → API Keys.
Alerts are sent to the ntfy app on your iPhone (topic set at install) and to email if that's set up in the settings file.
Your other Pi apps read this feed so they use your own garden readings.
Every day at 23:59 the Pi saves that day's readings as a spreadsheet file (CSV), and adds a line to a running daily summary. Just after midnight it tops the file up with the last readings of the day. The files stay on the Pi in , which you can also open with WinSCP.
Register your station on each site, then enter its station ID and key here. Uploads only run while the station is live.
On the PC that ran the WeatherLink program, your history is in monthly files named like 2019-07.wlk, usually in a station folder inside C:\WeatherLink. Choose the whole folder, or pick the files. Months you don't have are simply left empty, and records already on the Pi are never overwritten.
Downloads your old WU station's history, one day at a time. Days already on the Pi are skipped, so it only fills gaps. WU allows about 1,400 days a day, so years of history take a few days. It pauses and carries on by itself.
The API key is not the station key you use for uploading. Get it at wunderground.com → My Profile → API Keys (WU offers it to members with a station that's sending data).
Brings your past weatherlink.com readings into the history charts. It only fills gaps and never overwrites the console's own records. WeatherLink only allows history downloads on a Pro plan.
