There are 3rd party zigbee sniffers available, but they’re not cheap I think.
Your device is supported, but probably needs a real battery, or it’s too far away from Homey or zigbee routers. Try to restart the app as well.
If that doesn’t help, I suggest to report the issue to Johan by posting a message here (click on link to open):
