The $twcweather system variable provides data from The Weather Company following the shutdown of the Weather Underground API that powered $weather. $twcweather was introduced in webCoRE v0.3.10a.20190223. See sample data below which is available for webCoRE installs running on the SmartThings platform.

Note: If you discover useful data that is not listed here, feel free to post in this thread so we can update this page accordingly.

If you are interested in data for bad weather alerts, try: $twcweather.alerts.

Forecast

15 day forecast; append the index to get an individual day. For example, $twcweather.forecast.temperatureMin[0] is today's low temperature.

Normally, [0] is today's data, and [1] is tomorrow's data... but initial observations indicate that the data shifts over to a new day at approximately 3:15am, not at midnight, as one would expect. So from midnight to about 3:15am, the [0] data will likely be displaying yesterday's data, and [1] will be the current day. Once the data shifts over, then [0] will go back to being today, and [1] being tomorrow. (IE: 20+ hours a day, [0] is today... 3+ hours a day, [1] is today... with events during the 3am hour potentially going in either direction)

To add to this confusion, some [0] dataPoints (for today) vanish shortly after 3pm. (IE:$twcweather.forecast.temperatureMax[0] returns null all afternoon and into the early morning hours)

⃰ clears throat ⃰ ... A special "Thank you" to TWC for forcing us to add extra code to work around this convoluted logic.

To see a real life example, we can look at $twcweather.forecast.dayOfWeek[0]

  • Fri at 11:03pm returned Friday ✅
  • Sat at 12:03am returned Friday ❌
  • Sat at 01:03am returned Friday ❌
  • Sat at 02:03am returned Friday ❌
  • Sat at 03:03am returned Friday ❌
  • Sat at 04:03am returned Saturday ✅ (Finally!)

2022 Edit: I have created a piston to out-smart this craziness.

Partial day forecast

The forecast includes morning and evening data for various attributes. The indexes begin at 0 for "this morning" so 2 is tomorrow morning and 3 is tomorrow evening (see the daypartName value). To show an icon for tonight's weather you would get the icon code with the expression $twcweather.forecast.daypart[0].iconCode[1]

Note that the first value for some attributes may be blank in the evening. For example, running a piston in the morning you may get $twcweather.forecast.daypart[0].cloudCover => [ 25, 79, 100, ...] but that same evening $twcweather.forecast.daypart[0].cloudCover => [ null, 79, 100, ...].

Preliminary testing shows that today's morning/daytime data [0] turns null shortly after 3PM each day, and the next day's data shifts to [0] and [1] shortly after 3AM. This means from approximately 3PM to 3AM, you will find [0] to be null, and [1] will show data from the evening/night in progress. This also means that at about 3AM, the data for the night in progress vanishes, and is replaced with data for the following day/night.

Here's my findings over 20 days/40 events: … (Graph shown here) 
* 22 changed between 2:58 and 3:10   (55% of the time)
* 10 changed between 3:10 and 3:20   (25% of the time)
*  8 changed between 3:20 and 3:36   (20% of the time)

Old icon sets

Several additional icon sets are available but all have a much more limited set of icons. We have ensured that the $twcWeather icon code numbers map to an approximately accurate representation in the old icon sets. While the old sets work we encourage use of the more expressive TWC and WU v4 icon sets.

All of the icon sets described on the original Weather Icons page work with the new codes, for example :wu-b-36: maps to the "sunny" icon in the "B" icon set.
