Severe Weather Information skill

Severe Weather Information

Checks your national weather service and notifies you when there are alerts for your region

The severe weather information skill can connect to dozens of weather alerting services, among them many from following lists:
severe weather information center
alerting world weather
meteoalarm

After installation go to home.mycroft.ai and select your preferred weather service from the list on the skills configuration page.
You can also set a “watchdog” that automatically checks for new alerts and notifies you…

Thanks for trying my skill and reporting this.
In the stdout you have provided I see some reoccuring error messages:

  1. Error: Timeout was reached
  2. dpkg-deb: error: subprocess tar was killed by signal (Segmentation fault)

Maybe there was a network error while you tried to install?
Did you try to install some other apt-packages before and that failed somehow and now your apt-database is somehow broken?
How old is the SD-card in your Mark-1 - maybe that card is too old (assuming a 24/7 usage of the Mark-1 one year is old) and is simply dying - which results in erratic behaviour when trying to write data to the card…?

The error messages at the end are kind of exspected errors as the libgeos-packages were not succesfully installed before but are required by the pip-install of the Shapely pypi-package.

I tried again, this time logging in with pi (and not su-ing to mycroft this time) and running the command with the “mycroft-” prefix. I got esstenially the same errors.

It is possible that some other apt stuff has mucked things up, perhaps through the requirements.sh of another skill, but I don’t recall doing anything like that on purpose.

Do you think a “factory reset” as described in https://mycroft.ai/wp-content/uploads/2017/06/Mark_1_User_Guide.pdf would suffice to cleanup/repair the apt stuff (if it is indeed a problem)? I don’t know if that does any kind of OS image work, or just purges skills and configuration files.

Hi @jrwarwick
sorry, I somehow missed your reply… as far as I know the RESET function from the Mark-I menu does only wipe your settings. After that you will have to go through the wifi setup and register the device again at home.mycroft.ai

Honestly, I don’t think this will help with your problem as either your apt database is corrupted or your SD-card is dying. Is flashing the Mark-I image to a new SD card a feasible option for you?

Yes, I think I can handle a fresh flashing on a fresh card. It will take me a little while to do this though. I’ll report back with results. Thanks, Dominik.

Good news: a completely fresh install on fresh SD card, updated, then installed Severe Weather Information Skill as the second skill installed; completely successful, as you predicted. MSM seemed very happy. Then I configured the skill on home.mycroft.ai, and that seemed to work fine. I decided to move some of the threshold settings down a bit since the area I live in actually has very little severe weather.


After saving configuration, I attempted to speak the test phrase “Are there weather alerts”, but alas, this failed. “An error occurred while processing a request in Severe Weather Information”. I can attach a larger excerpt of the log, but it looks like this is the problem:

21:34:07.185 | ERROR | 857 | mycroft.skills.mycroft_skill.mycroft_skill:on_error:798 | An error occurred while processing a request in Severe Weather Information Traceback (most recent call last): File "/opt/venvs/mycroft-core/lib/python3.7/site- packages/mycroft/skills/mycroft_skill/event_container.py", line 66, in wrapper handler(message) File "/opt/mycroft/skills/severe-weather-information-skill.domcross/__init__.py", line 106, in handle_information_weather_severe self._check_for_alerts() File "/opt/mycroft/skills/severe-weather-information-skill.domcross/__init__.py", line 102, in _check_for_alerts self.alerts = self.get_filtered_alerts(feed.entries, max_entries=5) File "/opt/mycroft/skills/severe-weather-information-skill.domcross/__init__.py", line 306, in get_filtered_alerts if not self.in_geo_location(info, longitude=lon, latitude=lat): File "/opt/mycroft/skills/severe-weather-information-skill.domcross/__init__.py", line 345, in in_geo_location for lola in area["polygon"].split(" "): AttributeError: 'NoneType' object has no attribute 'split'

More good news: when I changed the location filter option to Area Description and gave my county name, the trigger phrase worked! So 97% successful test, now. Just a small problem with getting lat/long from the Mycroft Device.
Beyond that, I cannot say when or if I would actually experience severe weather to test the active/automatic notification of the condition.

You might be interested in the new geolocation API that we’ve added to the backend.

It’s not documented yet, but we’ve started experimenting with it in Skills eg this branch of the Date-Time Skill

That is exciting news, Gez. I have long anticipated the day when I would be able to wake up groggy and mumble: “Hey Mycroft, where are we?” and he unconfuses me. The ever-alert adventure buddy.

@jrwarwick thanks for providing me your location data (through PM)

Unfortunately NWS/NOAA does provide longitude/latitude polygon data for some, but not all areas. For the area you are living the polygon data is missing - which caused the exception you have reported. I have pushed a fix for that error.

In order to get weather warnings for your area you may want to look up your county/zone code at https://alerts.weather.gov, then in the skills settings change location-filter to “geo-code” and enter your county/zone code to “location description”

@Dominik your suggestion seems to work just fine. Using City, State styled “Area Description” seemed to work, too, interestingly.

I just noticed the faceplate display complete with general sky condition graphic: very nice touch!

One small suggestion: add a little more utterance analysis for this case of habitual speech pattern: I tried asking “are there any weather alerts in my location?” and “are there any weather alerts in my area?” to which Mycroft replied that he didn’t know about that location. Maybe include a few more common location phrases like “around here”, “the area”, “near by”, too and just interpret them to mean “use the skill configured default location”.

@jrwarwick Thanks for testing and your suggestions how to improve the phrases - this is very helpful for me as non-native English speaker. I will update the intent-files soon…

FYI, Now that I’ve had an explicit geocode in there for a while, and seen a couple of reboots, I am still seeing this in the background activity periodcially:

Did you enable “Automatic alert” in the skill settings?

Yes, with 15 minute interval:

Also, perhaps unrelated, I just noticed mismatch of scheduled event names: “SevereWeatherInformation” vs “SevereWeather”

Good observation, looks like you found a little bug. Will take care of it soon and report back here when it is fixed.

Another minor, more “cosmetic” issue: when pronouncing the output from alerts.weather.gov, the summary provided included asterisk characters, which Mycroft pronounces, i.e., by saying the work “asterisk”. At a glance it looks like this particular weather information feed is using the asterisk as some kind of delimiter of sorts (rather than an indication of emphasis, which I would consider more typical).

Considerably more tricky, so just FYI: Mycroft also pronouned the timezone abbreviation like a word “acksst” instead of saying something like “Alaska Standard Time”.

Sample of speech transcript from cli:

There are the following alerts DEBUG output
High Wind Warning issued February 20 at 4:47AM AKST until February 20 at 3:00PM AKST by NWS Juneau skills.log, other
…HIGH WIND WARNING IN EFFECT FROM 9 AM THIS MORNING TO 3 PM AKST THIS AFTERNOON… * WHAT…Southeast voice.log
winds 35 to 45 mph with gusts up to 60 mph expected. * WHERE…Cape Fairweather to Cape Suckling Coastal
Area. * WHEN…From 9 AM this morning to 3 PM AKST this afternoon. * IMPACTS…Damaging winds will blow
down trees and power lines. Widespread power outages are expected. Travel will be difficult, especially

Eventually found time for updating this skill:

  • fixed some bugs (scheduler etc.)
  • removal of unwanted “*” and “…”
  • changes for Mycroft 20.02 (some API functions were changed or deprecated)
