Here are the clusters from sensor and light. Is there a manual or video explaining direct binding using deCONZ?
Perhaps Philips Hue Smart Button - Support Request · Issue #2077 · dresden-elektronik/deconz-rest-plugin · GitHub ?
But this is the method for 2 devices, need to use the “group bind” check, and need to find/create the group first.
I think it s easy to use the API and the “special group”, when you add a sensor that support this feature, deconz create a special group in the API (it s the one you use on the old web app), you just need to add light device to this group and deconz will make the magic.
From Ebaauwn link
As I understand, Phoscon, unlike the old web app, doesn’t support the bound group (apparently it’s too confusing). Instead, it “plays sensor” with the controller. It creates rules to control the lights (through a group)
Was, what I was trying to say, the old web app use “raw zigbee” mode, that work without the coordinator.
Phoscon have more feature, but not the same working mode, and I think it need the coordinator for them.
