January 13, 2018 | Version 2.6

En la versión anterior le puse una estrella, pero porque me costó ver "algo". Ahora sé que muchos de los problemas de este widget no tienen nada que ver con el desarrollador. No puedo darle 5 estrellas principalmente porque no estoy en Estados Unidos: 1-Weather Underground falla mucho. En mi caso, no se ve nada si le pongo el zoom al 3 o menos (error IQ), pero veo el mapa si le pongo el zoom al 4 o al 5. De todas formas, en mi zona no he podido ver ni una sola nube por esta fuente, lo que me hace pensar que no va muy bien en España. ¿O sólo mostraría nubes de lluvia? Si es lo segundo, tendré que comprobar la información cuando esté lloviendo aquí. 2- Aeris sí parece que funcione, pero al no tener colores en las nubes, no parece la información más útil del mundo. WUnderground pone colores y eso nos sirve para saber si lo que vemos trae lluvia o no. Lo que muestra Aeris... poco más o menos lo podemos ver con los ojos si el horizonte está visible. Pero, de todas formas, me parece que la aplicación tiene mucho potencial. Si WUnderground empieza a ofrecer mejor soporte (y corrige fallos) por España o Aeris añade la opción de ver los colores en las nubes, podremos hacer rutas más largas estando un poco más tranquilos.

Amazing work getting an app like this to work on a resource constrained platform like the FR235. Only request would be for to be turned into a data field (if this is possible) so that the radar could be checked whilst in the middle of an activity. As a cyclist I would happily contribute for functionality like this.

Thanks for the great suggestion, unfortunately data fields are prevented in the current CIQ platform from using the communications api's necessary to retrieve the radar image. For the watches, this makes the widget less useful. On the cycling devices, Edge series, the widget is accessible during an activity and can be called up when you want without affecting the activity.

have API key for WeatherUnderground and Aeris Weather. I have put both in on Manage Apps, and my Epix is pulling up. ERROR CODE: -300 0 That's after refreshing radar for Aeris and Weather

Developer Reply
January 10, 2018, sabeard

Error code -300 is a network timeout. Usually this means there is a problem with the data source server. Please use the contact developer link and I will be happy to help troubleshoot the app.

It appears i need to buy an API key. I'll use my phone for the radar if that is the case. But, nice concept

While you need to "buy" a key, the developer key is free and fine for personal use.

Garmin Edge 1000 = “IQ!” Error. No info.

Developer Reply

Please use the contact developer link to send an email. I will be happy to help troubleshoot. So far the things I have seen cause the app to crash is trying to download the image with a poor internet connection, or an incorrect API key.

December 30, 2017 | Version 2.5-upd

Garmin 1030. Weather underground radar looking for Api key. How do you get one. Otherwise I can't get it to work

Developer Reply
December 30, 2017, sabeard

To get your key, go to and login. You should see a tab for "Key Settings". This screen should show your key or allow you to generate a new one.

December 26, 2017 | Version 2.5-upd

The same problem as others. Getting error 2. Other apps works so it is not the connecrion between phone and watch

Developer Reply
December 26, 2017, sabeard

Please use the contact developer link to contact me via email to help troubleshoot. Note, that the image size is much larger than the data retrieved from other apps, thus the weather radar is more sensitive to an unstable connection between the phone and device. So it could still be the connection between the phone at watch. :-)

December 12, 2017 | Version 2.5-upd

Installed on my 1030. Constantly get an error -2 after the "Retrieving Image" message is on the screen for over 2 minutes. It says it is running version 2.5 I assume on the top. GPS Good is the message below. Would be great if this worked.

Developer Reply
December 14, 2017, sabeard

I am sorry to hear the app is not working for you. The error -2 means that the link between the device and phone is getting interrupted during the transfer. The app is dependent on the connection to the phone and a reliable connection to the internet. After checking both of these, pleas use the contact developer link and I will try to help troubleshoot.

December 12, 2017 | Version 2.5-upd

Very good but crashes and restarts my watch when there are errors (like error 2 or -101). What is error code 2 and -101 ? For info I have a Vívoactive HR.

Developer Reply
December 14, 2017, sabeard

Those error codes indicates there are problems with the Bluetooth connection to the phone. The app is dependent on a reliable connection to the phone and the internet. Please use the contact developer link to provide more info on your setup. It may be necessary to contact Garmin support to see what is causing the watch to crash. Usually that is a FW issue.

Funciona en Europa? Me aparece el mapa siempre vacio.

December 5, 2017 | Version 2.5-upd

Okay I guess but it's so slow I could easily pull my phone out of my pocket, check the radar, and put my phone back in my pocket before this widget will show the image. Doesn't matter which source, both are slow.

Developer Reply
December 5, 2017, sabeard

On watch devices the download speed is limited due to the Bluetooth LE limited bandwidth. It is much faster on the cycling computers where the phone is less accessable and harder to pull out to check.

December 4, 2017 | Version 2.5-upd

Thanks, working great on my Fenix5x!!!

Non funziona su garmin edge 1000

Developer Reply

The app works fine on the Edge 1000. That is what I developed for and use the app on. For it to work you must have the API key configured as described in this post.

November 17, 2017 | Version 2.5-upd

Good morning. The app is ok, but after I open it, it says “gps good” and after 1 seconds I read “error 0” on the screen. I use a Garmin Edge 820, and an iPhone 6 with iOS 11.1.2 Can you help me? Thank you for your time. I tried to use the developer button, but I’m not able to send the request. That’s why I wrote here. Cody

There is not much I can do to help troubleshoot through a single review reply. Please try the contact developer link again. If you tried from your mobile, then please try from a desktop PC. From my experience, Error 0 means either there is something bad with your link to the phone or the weather service returned a bad image. If it is a bad image, the only thing you can do is try the widget again later.

October 26, 2017 | Version 2.4

Funciona perfecta

October 21, 2017 | Version 2.3

Si os da error clave 0 es porque es errónea. Para generar la clave debéis ir a y alli registraros como desarrollador y os genera la clave. Creo que solo funciona en EEUU, Canadá y Australia. De los demás sitios como Europa no tienen datos. Si no es así que me corrija el desarrollador.

October 21, 2017 | Version 2.3

This app works great on my Vivoactive 3. I use the Weather Underground API. I work outdoors and this app is perfect to let me see if I have any bad weather coming my way.

October 20, 2017 | Version 2.3

The widget works beautifully on my Edge 1030. With two weather sources and five zoom levels to choose from it has everything I need! Be sure to obtain the required free keys at the URLs posted here, a quick and simple process. Many thanks to the developer for providing such a useful app and spending endless hours working on problems created by the weather providers!

October 17, 2017 | Version 2.3

Works great on my fenix 5x. Highly recommend. Props to the developer who was very responsive and helpful in getting the widget configured correctly. Make sure to complete the following steps which are outlined in the widget description. Please use the following link to register for a Weather Underground API key. The free developer version is perfect for personal use. It does not matter which plan type you select. Please use the following link to sign up for the free AerisWeather developer account. You will need to renew the account every 2 months.

I am sorry to hear about the app not working on the Edge1030, Can you send me a note using the contact developer link with the phone, phone OS, device FW version and GCM version you are using. I am trying to work with Garmin to find a pattern of cause for others which are reporting similar problems.

Myotis, sorry my post about releasing version 1.3 right after yours was intended to be in response to your post in an effort to improve the ability to troubleshoot. I never received any additional feedback that later versions did not fix your issue. Please return to the forum or use the contact developer link to let me know more about your setup including Phone type and OS version, GCM version and device FW version. I will be happy to help troubleshoot, I just did not know you still had a problem.
