Revision as of 02:30, 5 August 2019

As of Aug 4th, I have been unable to locate an official document for the weather alerts, so we have been gathering data the old fashioned way, and combining our findings on this page.

If you see a unique alert for your location, please contribute your observations to this thread.

If you are interested in $twcweather data that is not an alert, check this page.

Introduction

Everything on this page focuses on $twcweather.alerts. This query will usually return [] unless there is an alert for your location. When that happens, up to 62 different dataPoints may be returned. Every one of them begins with $twcweather.alerts followed by a period, and ending with the dataPoint listed below. (such as: $twcweather.alerts.eventDescription) There are a couple of tables below that got a bit crowded, so some of them will not list the beginning portion, but it is important to remember that every single command on this page begins with $twcweather.alerts.

It is unfortunate, but a weather alert cannot be used as a trigger. To get alerts for your area, you can program a piston to periodically make a query. (mine is set to run every 15 minutes, but other triggers can work as well) Please program strategically so we don't hammer the weather server too frequently. Any more often than 4 times an hour is a waste of resources/pointless, and might encourage SmartThings to start charging us for this data. (since they are billed for each query)

For the most part, the "unknown dataPoints" are listed first, so they get the most exposure & hopefully more contributions. These will be followed by the dataPoints that are likely the most useful. The final category will be dataPoints that rarely change.


.

Needs More Information Gathered

We really need more data responses for this section. Please add any unique observations to this thread.

Unknown dataPoints

Expression Sample value Notes
$twcweather.alerts.areaTypeCode "Z", "C" Returns "Z" 80% of the time
$twcweather.alerts.categories.category "Met" Metropolis??
$twcweather.alerts.categories.categoryCode "1"  ??
$twcweather.alerts.significance "A", "S", "W", "Y"  ??
$twcweather.alerts.disclaimer null  ??
$twcweather.alerts.eventTrackingNumber 0003  ??

$twcweather.alerts.flood

The dataPoint "flood" is usually null, but when there is an alert for possible flooding, then these dataPoints may appear:

Expression Sample value Notes
$twcweather.alerts.flood.floodCrestTimeLocal null  ??
$twcweather.alerts.flood.floodCrestTimeLocalTimeZone null  ??
$twcweather.alerts.flood.floodEndTimeLocal null  ??
$twcweather.alerts.flood.floodEndTimeLocalTimeZone null  ??
$twcweather.alerts.flood.floodImmediateCause "Excessive Rainfall" Needs more examples
$twcweather.alerts.flood.floodImmediateCauseCode "ER" Needs more examples
$twcweather.alerts.flood.floodLocationId 00000, AFBI2  ??
$twcweather.alerts.flood.floodLocationName "N/A", "White River at Apache Tailwater"  ??
$twcweather.alerts.flood.floodRecordStatus "N/A"  ??
$twcweather.alerts.flood.floodRecordStatusCode "OO"  ??
$twcweather.alerts.flood.floodSeverity "None"  ??
$twcweather.alerts.flood.floodSeverityCode "N"  ??
$twcweather.alerts.flood.floodStartTimeLocal null  ??
$twcweather.alerts.flood.floodStartTimeLocalTimeZone null  ??


.

Important & Useful

I think most of our coding will be centered around the data found in this section.

Alerts

It appears that these 5 dataPoints are connected, so this table is shown a bit differently than the above tables. To conserve space, the first three columns are marked with numbers that match this:

  1. phenomena
  2. productIdentifier
  3. eventTrackingNumber
Each dataPoint below must begin with $twcweather.alerts. (Such as: $twcweather.alerts.phenomena)
1 2 3 eventDescription headlineText
CF CFW 0024 Coastal Flood Statement Coastal Flood Statement from FRI 8:00 PM EDT until SAT 12:00 AM EDT
FA FLS 0156 Flood Advisory Flood Advisory from THU 5:21 PM EDT until THU 7:15 PM EDT
FF FFA 1 Flash Flood Watch Flash Flood Watch until WED 9:00 PM AST
FG NPW 0003 Dense Fog Advisory Dense Fog Advisory from SAT 5:40 AM EDT until SAT 10:00 AM EDT
FL FLS 0065 River Flood Advisory River Flood Advisory until SUN 7:00 AM CDT
HT NPW 0003 Heat Advisory Heat Advisory from TUE 10:00 AM EDT until TUE 9:00 PM EDT
SV SVR 0106 Severe Thunderstorm Warning Severe Thunderstorm Warning from WED 6:14 PM CDT until WED 6:45 PM CDT
SV WCN 0547 Severe Thunderstorm Watch Severe Thunderstorm Watch until WED 9:00 PM EDT
TAW AWW 0000 Airport Weather Warning Airport Weather Warning until FRI 2:15 PM CDT
TSG SPS 0000 Significant Weather Advisory Significant Weather Advisory until FRI 4:15 PM EDT

Descriptions

It appears that these dataPoints are paired up, so this table is shown a bit differently than the above tables.

Each dataPoint below must begin with $twcweather.alerts. (Such as: $twcweather.alerts.certaintyCode)
certaintyCode certainty Notes
1 Observed
2 Likely
3 Possible

5 Unknown

Times

These seem to be the most helpful times listed.

Expression Sample value Notes
$twcweather.alerts.issueTimeLocal 2019-07-30T03:21:00-04:00
$twcweather.alerts.expireTimeLocal 2019-07-30T21:00:00-04:00
$twcweather.alerts.onsetTimeLocal 2019-07-30T10:00:00-04:00 Usually returns null
$twcweather.alerts.effectiveTimeLocal 2019-07-30T10:00:00-04:00 Usually returns null
$twcweather.alerts.processTimeUTC 1564471315
$twcweather.alerts.expireTimeUTC 1564534800

Location

These seem to be the only helpful locations, that may change based on the location of the alert.

Expression Sample value
$twcweather.alerts.areaId "NYZ179", "ANZ335"
$twcweather.alerts.areaName "Southern Nassau County", "Long Island Sound West of New Haven CT/Port Jefferson NY"

Not Very Useful

The following dataPoints seem mostly useless, but we are still gathering data.
If any of these dataPoints are found to be helpful, I will relocate it to the appropriate section above.

Times

I suspect these dataPoints will only change twice a year when we change our clocks.

Expression Sample value
$twcweather.alerts.expireTimeLocalTimeZone EDT
$twcweather.alerts.effectiveTimeLocalTimeZone EDT
$twcweather.alerts.issueTimeLocalTimeZone EDT
$twcweather.alerts.onsetTimeLocalTimeZone EDT

Locations

I suspect these dataPoints may never change.

Expression Sample value
$twcweather.alerts.adminDistrict New York
$twcweather.alerts.adminDistrictCode NY
$twcweather.alerts.countryCode US
$twcweather.alerts.countryName UNITED STATES OF AMERICA
$twcweather.alerts.ianaTimeZone America/New_York
$twcweather.alerts.latitude 40.01
$twcweather.alerts.longitude -75.01
$twcweather.alerts.officeAdminDistrict New York
$twcweather.alerts.officeAdminDistrictCode NY
$twcweather.alerts.officeCode KOKX
$twcweather.alerts.officeCountryCode US
$twcweather.alerts.officeName New York City
$twcweather.alerts.source National Weather Service

Unique dataPoints

Not sure of the relevance here... They change at almost every alert.

Expression Sample value Notes
$twcweather.alerts.detailKey "8db0a39f-2c26-39c9-862b-37f7256f3d45",
"681e5182-53c2-394e-9440-c4a426680f82"
36 characters, Might linger if the alerts are similar
$twcweather.alerts.identifier "f1bac66b482866c05c82fc3462978a17",
"6e39ac945ef3c7be4593d528be6388d4"
32 characters, Might linger if the alerts are identical

Conclusion

The data gathering data phase is still in progress, so this page will be updated whenever new data is posted to this thread.

I am excited to see what kind of pistons we can create for these weather alerts! Don't forget to share your creations on the forum...
