Hey @anon. We do not have a product like this at this time, but we do have an alternative! The Ring Alarm Keypad can play chirps that it picks up from your sensors, so you can always get this device and have on set up in your garage. This may be a good idea all in all, as you can use the panic button feature from the keypad if needed as well! Please note that the Keypad is designed for in home use, and another range extender may be needed as well if the Keypad has troubles staying connected to your Base Station from out in the detached garage. Hope this helps!
