Embed variable into a URL on Custom Tile

[Chris_Boyce]

Hi all,
I’d like to take an attribute from my WeatherUnderground driver (say, an icon code that represents the image for that day’s weather conditions, hence it’s dynamic) and embed that into a URL that would retrieve the actual icon image from GitHub into the tile itself. I’ve figured out how to set a variable for an attribute and keep it updated, so that part is good.

The closest thing I’ve seen to grabbing a variable’s value and making it into a usable URL for sharptools, is by means of Custom Tiles → JS Library. I can do some coding but I’m not good with Java. Is this the only way, and could someone give me a hand over this hurdle?

Many thanks!

Can you share a sample URL to an image and what the related variable value would be?

I would also note that there’s a community developed Open Weather Custom Tile that you might find interesting:

Weather Tile - Open Weather - Current and Forecast

Sure, URLs look like:
https://raw.githubusercontent.com/dJOS1475/Hubitat_WU_Driver/main/wuIcons/39.png

…where the 39 in this case is the icon for rain. That’s all I would likely use a variable for, is the code for the needed icon.

I’m also open to other sources for “todays/tonight’s weather” such as Open Weather, as long as it supports Canadian locales, metric, etc.

Thanks Josh!

Yes, the custom tile I linked to has support for global regions and locales (even localizing the weather terminology to a local language).

Here’s a sample Custom Tile that does what you’re asking for. It demonstrates the basics of using a Variable as a ‘setting’ for the Custom Tile and using the variable value within the Custom Tile:

Wow you even wrote up an entire prototype. Top notch customer service, Josh. I will be subscribing today. Now I just need to decide on Open Weather or custom. Maybe both! Thanks again!
