@asemev, deCONZ exposes some api you can talk to. See RaspBee binding compatibility
I bought some Dresden raspBee modules many months ago, but gave up someday on further trying to integrate via deCONZ. Meanwhile, it might be much better…
Anyway - I personally opted now for @Chris’s Zigbee binding.
Yes, as @rlkoshak said, it’s work in progress.
And yes, the raspBee or other Dresden Electronic coordinators (USB type) are not supported (yet?).
But: What’s implemented in the Zigbee binding so far is already working quite well!
All my Zigbee lamps from three different vendors (Philips, Osram, Ikea) are working with switching/dimming (for the RGB variants the color control is working as well) … without any separate gateway/bridge/hub
