Get official accessory status from within custom plugin
### Current Situation

Hello,
first of all thank you for homebridge efforts - it is superb tool! 
I'm trying to develop my first plugin (outside gate opener) which needs to read current status/position (contact sensor)  from existing accessory added by Aqara official homekit integration. Is there any way how to access that?

I can think of some workarounds like setting automation for the sensor to sync the current status opened/closed using e.g.  dummy switch from homebridge which can (I believe) accessed more easily from my custom plugin. 

What would you recommend here?

Thanks!
