I don't think the original HyperDeck Studio Mini supported HDMI timecode output, and I'm not sure whether the updated HyperDeck models support this or not either. And even for the SDI start/stop record flags, I don't know that the HyperDeck actually generated these flags on its SDI outputs when pressing the HyperDeck record button (or triggering HyperDeck recording via the Ethernet control protocol).
I think it should be possible to get the HyperDeck to include timecode in its SDI outputs (if the Timecode Output setting is turned on). And then if you extract the timecode from the Hyperdeck SDI output (with something like a Teranex Mini SDI to HDMI or Teranex Mini SDI to Audio), you could probably feed that timecode to the MixPre's Aux input. Then set the MixPre record trigger to timecode run (rather than using the start/stop record flags).
Another possibility is to use the MixPre's USB port which supports USB keyboard commands for control of various actions (such as start/stop recording). So you could use a USB keyboard emulator to send commands to the MixPre from some other source. For example, recent versions of the Rasbperry Pi with a USB OTG port (like the Raspberry Pi 4 and Raspberry Pi Zero) can be configured in USB device mode (rather than the more typical host mode) and used to emulate a keyboard. There are various tutorials for this online: https://randomnerdtutorials.com/raspber ... board-hid/

Or this project which is a slightly different approach, but along the same lines to create a network enabled USB keyboard emulator: https://github.com/Flowm/etherkey
Then you could maybe use one of the Generic network request modules in Bitfocus Companion to send a start/stop command to the Raspberry Pi over the network and have it send the equivalent keyboard command into the MixPre.
