WeatherFlow Widget for Scriptable

Requirements

• You're running iOS/iPadOS 14.
• You've installed Scriptable (https://scriptable.app).
• You own a WeatherFlow weather station.

Installation

1. Create a new script in Scriptable and paste the wxflow-widget.js code into it.
2. In a web browser, log on to your WeatherFlow account at https://www.tempestwx.com.
3. Copy your station id from the address bar in your web browser to the STATION_ID variable in wxflow-widget.js (for example, if your address is https://tempestwx.com/station/12345/, your station id is 12345).
4. Go to Settings, scroll to the bottom and click Data Authorizations, then create a personal use token. Copy your token into the API_KEY variable in wxflow-widget.js.
5. Long-press anywhere on your home screen to enter edit mode, tap the + in the top left corner, select Scriptable, and add the small variant of the widget.
6. While in edit mode, tap the new widget, and configure it to use the wxflow-widget.js script.

Recent changes

• Configuration options to vary the background color or temperature text color according to your outdoor temperature.
• Parameters now display in the units you've specified in the Tempest app.

Acknowledgements

• 93ben on the WeatherFlow forum for help with the temperature colors and pointing out the user-specified units returned by the API.
• GaryFunk on the WeatherFlow forum for posting a consolidated list of formulas and conversions.
• grantharrison on the WeatherFlow forum for suggesting a cleaner layout.

Hi Keith! Got some time due to I can’t paint the house when it’s raining. I followed your recommendation but the result was; {"status":{"status_code":404,"status_message":"NOT FOUND"}} I even followed the format given by WeatherFlow by changing the api key to token as in their example. I even created a new api key/token but with the same result. This is the URL I used, have just copy past the required information so it should not be any typing errors https://swd.weatherflow.com/swd/rest/observations/station/Fiskarhöjden , Saltsjöbaden?token=175e2b67- b046-4b52-8b0c-361a04b5454f I will contact support at WeatherFlow to hear what the problem might be, hopefully do the have a solution to the problem. Best regards Richard Från: Keith Thomas ***@***.***> Svara till: wxkeith ***@***.***> Datum: tisdag 21 juni 2022 14:01 Till: wxkeith ***@***.***> Kopia: Maricha09 ***@***.***>, Mention ***@***.***> Ämne: Re: wxkeith/README.md @wxkeith commented on this gist. @wxkeith Just what I was looking for, after a bit of struggling did I get everything inputted right I believed but receive an error for lines 29 - 30!?? This value is coming from The Tempest, the only possibility I could guess caused the error is for some reason the two ö (lowercase o umlaut) in the station name "Fiskarhöjden, Saltsjöbaden" is somehow not accepted. Any idéa on a way to fix the error? @Maricha09 Apologies for the really late reply, did you ever get this to work? I tested passing around your station name in the code in a few places and it doesn't have a problem. So unless it's coming in from the WeatherFlow API in some unexpected way, there is likely a problem with your API key or station ID. I would start by double checking those values. You can test them in a web browser by building a URL of the format: https://swd.weatherflow.com/swd/rest/observations/station/{station_id}?api_key={api_key} For example: https://swd.weatherflow.com/swd/rest/observations/station/12345?api_key=11111111-1111-1111-1111-111111111111 (this is not a valid station id or api key and will fail, but replacing them with your values should work!) — Reply to this email directly, view it on GitHub, or unsubscribe.

@Maricha09 What is your numeric station id? This should be visible in the URL immediately after you log into the Tempest portal at https://tempestwx.com. Be sure you're setting this in the CONFIG_STATION_ID variable at the top of the script.

Hi Keith! Just to let you know that the problem is solved now, I had left out the quotation marks in the API-key 😏 Have a nice summer! //Richard Från: Keith Thomas ***@***.***> Svara till: wxkeith ***@***.***> Datum: onsdag 22 juni 2022 18:29 Till: wxkeith ***@***.***> Kopia: Maricha09 ***@***.***>, Mention ***@***.***> Ämne: Re: wxkeith/README.md @wxkeith commented on this gist. @Maricha09 What is your numeric station id?
