Common issues and misusages

> Error -300 (HTTPS)

The -300 error, is described by Garmin to be a timeout error. But, if the error appears instantly after launch, you are probably facing something else. As described in this thread, depending of the version of IOS or Android, Garmin doesn't permit anymore to communicate in HTTP with something other than localhost. You must use HTTPS.

The error also appears when the certificate is self signed (I didn't do the test to add the CA certificates to the smartphone, perhaps it can solve the issue). You can use free service as Let's Encrypt to create a certificate which the smartphone will approve. If you configure apache, don't forget the "SSLCertificateChainFile" parameter in addition of "SSLCertificateFile" and "SSLCertificateKeyFile".

If HTTPS is really not an option and your device have WiFi and/or LTE, because HTTPS is not required with WiFi or LTE, force sending request throught WiFi could be a solution. Take a look on "media" option.

> Memory

For supported watches which only have 60kb of memory, namely :

  • Fēnix® 5, Fēnix® 5s, Fēnix® Chronos
  • Forerunner® 245, 645, 935
  • Quatix® 5
  • Venu™
  • Vìvoactive® 3
  • Note: "music" versions are not affected.

You can configure about 8 to 15 actions on these watches depending on their complexity, then memory could be full.
If the yellow exclamation mark appears, try to limit the number of configured actions.

> Garmin Express vs ConnectIQ

Many users reported issues when configuring the settings from Garmin Express. It's not related to my widget but due to GarminExpress. Please prefer to use ConnectIQ app to configure the settings of the widget.
Is also seems that upgrading from GarminExpress could alter already configured settings, please also prefer ConnectIQ to upgrade the widget.

Obviously I don't have all the physical devices. I do a test for each reference with the simulator, but it does not always perfectly reflect the real rendering. Thank you for being indulgent and do not hesitate to send me pictures of the rendering or requests for improvements.


  • Add wifi support to send the request. From now, I perhaps find a way but it may take about 20s/30s to launch the query... OK
  • Add PUT method support. OK
  • Add support or array in resDisplay. OK
  • Add support of older devices. Honestly not the priority, it will take lot of time and complexify the code for a probably poor visual result...
  • Add option to add custom http headers to the query.
  • Add option to send POST as plain-text.
  • Always try to optimize memory.
