HomeBridge *to* SmartThings

So I have HomeBridge and smartthings humming along. Requisite plug ins installed and I can see the requisite smartthings devices in Homekit and control them with Siri. So far so good.

How can one accomplish the opposite? I have a set of devices in Homebridge enabled through a plug-in that I would like to expose back to smartthings as sensors and swirches. Any integration available for that flow?

Thanks.

The only thing I’ve been able to pass back and forth is a binary state (on/off). You can create a virtual switch in ST and present it to HomeKit through HomeBridge. Then create a HomeKit automation to turn on/off the the virtual switch when the physical one turns on/off and vice versa. That way either system can control the device and the state should stay in sync.
