Rails version 2.18.0


NOTE: This post describes combined new features of releases 2.18.0 and 2.17.0, since they were made in quick succession.

What’s new

  • 6 new data points (stress, body battery, respiration rate, time to recovery, VO2Max (running + cycling)*
  • Battery in days added if battery info is displayed in data fields Opt 1 – Opt 4*
  • Location fallback to Garmin weather if not available from activity**
  • Oversize HR and seconds / Oversize data options now also available on AMOLED/LCD devices
  • 2 more custom colors
  • 2 additional data fields (Opt 5 between Opt 1 and Opt 2 and Opt 6 between Opt 3 and Opt 4)
  • Top icons text hidden when the icon color is the same as the background color
  • ‘Feels like’ can be selected for all data fields
  • ‘Chance of rain’ renamed to ‘Precipitation’. If it is selected for Opt 1 – Opt 4, precipitation volume [mm] will be appended if available
  • More data options for ‘Right data’ and ‘When seconds off, show’ fields

Important notes


(*) The highly anticipated new data is only available on some devices and may require firmware update from Garmin before it starts working. So it may happen that it will not be displayed on your watch yet (you will see “–” instead).

To check if your device is compatible, go to the watch menu System / About / SW versions and look for “Connect IQ System 5” or “API level” higher than 3.3.0.

It has been tested OK on Garmin’s simulator and on a real Venu, so hopefully it should be working on your watch too, as soon as the update to System 5 arrives.

Connect IQ System 5 has rolled out on a number of devices with more coming:

Rails version 2.15.0

  • Added option for “Active bar” (= opposite to “Move bar”)

Standard move bar grows while you stay inactive and is cleared when you start moving again.

Active bar is the opposite. It is full when you are active and decreases after a period of inactivity.

  • Added battery level option for data fields on some devices (including solar charging level if supported)

This option is not available on Venu family.

  • Attempted a workaround for the problem with waking up from night power save mode

There seems to be a firmware problem with the watch reporting incorrect wake up time set in Garmin user profile (looks like adding a random number of seconds to the specified time). As a result the waking up from the night power save mode would not work. This workaround may help but it is not guaranteed to wake up from the power save mode at the exact wake time specified in user profile.

Rails version 2.14.0


Countdown timer entry method changed:

  • This is an attempt to avoid problems caused by the calendar widget in the settings in Garmin apps
  • In addition, now the timer can be set with minute accuracy
  • Counter expiry time is entered as YYMMDDhhmm (year, month, day, hour, minute), without spaces, all must be 2 digits)

For example, to set the timer at 12 July 2022 12 noon, enter:
