Amazon Alexa skill: Connect your Alexa/Echo to your Weather Underground Personal Weather Station

Want to ask Alexa for the readings of your personal weather station? Now you can! 

Finally, an Alexa skill that pulls the data from your personal weather station via Weather Underground.

Reports current conditions including temperature, humidity, wind speed, wind direction, pressure, rain in the past hour, rain in the past day, and much more. You can ask for all conditions or just a specific condition.

May 29, 2017: Coming soon: a better way to enter the station ID. I'm working on an enhancement that will allow one to pick from a list of stations based on ZIP Code. The skill will make use of your Echo's postal code and give you a list of stations to pick from. This will be an alternate way of specifying your Station ID vs. the sometimes frustrating task of getting Alexa to recognize the letters in your Station ID. Stay tuned...


May 19, 2017: Added support for metric system. To use metric units, say SET UNITS METRIC.

I've included a basic forecast (via Weather Underground data) as well.

All you need is the Station ID and a free API key from Weather Underground. You can get your API key by going to www.wunderground/api and signing up. All you need is the Developer option. 

Please note that this skill is geared towards people that want to get current data from their person weather stations vs. those that want detailed forecasts.

If you really enjoy my app, donations are always appreciated.  You can donate to me via PayPal

To set the API key and personal weather station ID:

  1. First, make note of your personal weather station ID. Most station IDs begin with the letter 'K' followed by a two-letter state abbreviation. Then there is a letter abbreviation for your town/city followed by some numbers.
  2. Next, get a Weather Underground API key by going to
  3. Sign in, if you haven't done so already.
  4. Select any of the "Developer" plans. There is no charge. Complete the process.
  5. Make note of your API key - it will be a series of numbers and lower-case letters.
  6. Have your API key and station ID noted down and readily available.
  7. Get Alexa's attention - say "Alexa" and wait for the confirmation tone and/or light.
  8. Say "Personal Weather".
  9. Wait for the app to say "Welcome to Personal Weather..."
  10. After you hear "Please say a command" and then the tone, say "SET KEY" followed by your API key.
  11. It may take a few attempts to get Alexa to recognize your API key. You can try using the NATO phonetic alphabet* if Alexa keeps having trouble understanding you.
  12. Once the app successfully recognizes your API key, it will let you know.
  13. Now it's time to set the Station ID. Get Alexa's attention - say "Alexa" and wait for the confirmation tone and/or light.
  14. Say "Personal Weather".
  15. After you hear "Please say a command" and then the tone, say "SET STATION" followed by your station ID.
  16. It make take Alexa several attempts to recognize your Station ID. You can try using the NATO phonetic alphabet* if Alexa keeps having trouble understanding you.
  17. If the app finds a valid Station ID, it will tell you the location associated with the station. If the station is correct, say "yes" when asked whether you'd like the save the station ID.
  18. Once you have the API and station ID set up, you should not have to enter them ever again.

* NATO Phonetic Alphabet

You may have to use this technique to get Alexa to recognize the letters in your API key and station ID. If you don't know the words associated with the letters, you may wish to note down the phonetic spelling of your API key and station ID before repeating the above instructions.

There seems to be a problem with the rain total and the rain in the past hour. Alexa reads out the wrong data not what is the actual data. Request: Would like to be able to set current conditions data. For example i would like to hear high wind in the current conditions. Great app!

Hey R Plenty,

I found and (hopefully) fixed a bug with the rainfall amounts. Can you try again?

As for being able to configure the current conditions output, I'll work on that...

I have tried 6 weather stations and Alexa says weather underground does NOT recognize any of them.

Blogger Kevin Key said...

Hi FJamer,

Soon I'll be updating the app to allow a station to be specified based on location. This should make the process of specifying a station much easier. In the meantime, have you tried using the NATO phonetic alphabet to specify your station? If you still have trouble, tell me the last three characters in your API Key and your station ID - then I can manually enter your station into the database for you.

She repeats back what I said so it's not that. Last three of API is 3e2 and the station ID is KSCCONWA28 or 40 or 21 or 20 or 34 or 30!

Fri Jun 02, 10:33:00 AM PDT

Fjamer: Try now. Say "Alexa, ask personal weather the current conditions." You can also say "Alexa, ask personal weather the forecast." "Alexa, ask personal weather the temperature." etc.

Thanks for taking the time and effort to create the Personal Weather Station Skill and making it available for other users! It works great.
If you can get the zip code interface working well that will be a great improvement! Getting Alexa to recognize the Station ID via voice commands was a challenge to say the least! Ha...
Thanks again and keep up the good work.
I'm new to the Alexa devices and all the smart home stuff, but if there is a way to use the IFTTT process and or setting alarms or notifications via the skill that would be really neat also.

Thanks Kevin! I am having a strange problem on my Windows Visa. When I run the smartHUB Reader after a restart of the machine it runs for roughly 24 hours and stops. I have to restart Windows again and it will work for another 24 hours. Is there a debug log file that I can look in to to see what is going on?

Is there a way we can get the skill to announce the temperature every hour or 30minutes maybe if it reaches a certain temperature kind of link a timer loop in VB. Maybe announce windspeed
every hour. Would be nice to hear Alexa issue an alert that the temperature has reached 0 or windspeed has exceeded 20 MPH. Not sure if a skill can do this.

Just installed your skill on Alexa. Great app with lots of potential for upgrade. As one person commented, would be nice to disable the weather reporting with my include wx station ID. Would also be nice to enable a shorter command than "Ask Personal Weather" all the time. But thanks for your work. Love the app.

This Skill looked promising, but I am stuck at trying to enter the API key.

I phonetically say the Key (and mixing letters a little publicly but the problem is the same):


And Alexa hears

2 becomes TO
Repeated several times with same result. I don't know whether that is your Skill or Amazon's voice decoding, but frustrating just the same.

Much thanks for this skill. Works very well for me. I have noticed one issue that I have seen before and I don't think it necessarily has anything to do with the skill. My PWS is:

The api here:

The skill reports everything the same as the api - except the pressure. The pressure is always a few hundredths of a degree higher - e.g. the api shows the pressure as 30.27 and the skill reports the pressure as 30.31.

I use an app - YoWindow:

I have it pointed to the PWS and it also returns everything accurately except the pressure. It is always higher. I thought with your experience with the skill, you might have some insight into the issue. Thanks.

Kevin, thank you for taking the time to create this app. I am unable to use it however because my API begins with a "4", which Alexa only recognizes as "for". I bought a PWS as a Christmas present for my blind husband to use with his Alexa but it looks like he won't be able to use it. Do you think you will ever have a fix for the "4/for" problem? Thanks.

Has anyone encountered Alexa repeating the city of the selected PWS? For example, Alexa states the correct temperature or rainfall or whatever I ask and then ends the report with “Location, Philadelphia in Philadelphia.” That is, “CityName in CityName,” a repeat of the city. Any ideas?

My alexa app would always identify the location of my PWS as being in Lee Boulevard Heights which is a suburb of Washington DC near Falls Church, VA, the same as listed in my Weather underground page. Within the last couple of days when I ask Alexa for current conditions it now identifies location as Washington. Why would this change have occurred? I did not change it and still as it was on WU. Any explanation would be welcome. Is it normal for the configuration to end up identifying your blog for additional help?

Hi all.

I'm aware of the recent issue where my Weather Underground Alexa skill is no longer reporting the Station Location. There is either a glitch with the Weather Underground API* or they decided to make an unannounced change to it. Unfortunately, the API* doesn't contain the station name anywhere at the moment. :(

I really don't know why Weather Underground has done this. And, if it's a glitch, why they haven't fixed it yet. I'm not 100% certain about the rest of you, but I'm still getting correct data from my own station on my own Alexa - despite it only announcing the city name of my station.

The best I can do in the meantime is to have my Alexa skill speak your Station ID instead. Hopefully sometime in the next day or two. Sorry for the lack up responses and updates as I've been quite busy with other things lately.

Thu Apr 05, 12:37:00 AM PDT  
Blogger Kevin Key said...

Hi all,

In regards to my Alexa skill no longer reporting your specific station name, I just found out why this is the case. Here's what Weather Underground has to say about this issue:

Unfortunately for now, we are removing the PWS name (from the API). This is in response to some new EU privacy rules which we are bound to follow to operate in Europe. While taking the time to address the EU issues we decided to beef up our privacy protections for everyone everywhere.

We want to make sure we maintain the right balance of protecting our users, and disseminating useful information, We expect this balance will evolve over time as our community of PWS owners weigh in on our stance.

In the meantime, I've modified my Alexa skill to report your Station ID instead.

I have sent two emails to WU regarding this Station ID/API change and requested them to at least reverse the change for US users if not everyone. In the meantime, how can I continue to use My Personal Weather skill in Alexa? It still requires and API when I try to set it up.
