It sounds like this device works with events (meaning there is no entity it’s just a bunch of triggers firing i the background…) you SHOULD be able to see events in developer tools
That said, Jack is absolutely right. Looks like is not good enough. It may look like x and act like x kinda but it is NOT X.
Just having the ‘zigbee logo’ is not enough to guarantee 100% operation. Because a thing called vendor specific clusters exist (a thing invented to allow vendors to have ‘custom’ functions means not all systems understand the vendor specific clusters and therefore don’t work.— unless someone writes something to make your chosen zigbee integration use it
So Yes probably event driven you may be able to find the event in dev tools. But if the event isn’t firing then you need to go see if the device is setup to send the event (and that would be the vendor specific config mentioned above)
For ZHA, you can read about adding custom device support here: Zigbee Guide: How-to add/setup local custom ZHA Device Handlers (also known as ”quirks”) in the ZHA integration
