As asked above, I am still looking for a simple start/stop remmot for the Osmo Action (1).
Needed for controlling the OA on my motor-bike.

Hi there. Thank you for reaching out. Unfortunately, we don't have any kind of remote controller for the DJI Osmo Action. However, you may use your mobile device to control the unit by downloading the DJI Mimo app on your mobile device. Thank you for your understanding and support.

The mobile app is not always easy and practical to use - such as in the OP's example.

Adding an auto-record when power is applied to USB would be amazing...
