Yes, the config within the app is not working. I had to go into the IDE and create a new device type to be able to use the simulator. There you can press the configuration button to force it to take the configuration. Press the config button and the button on the smokesensor three times right after to wake it up and it should update the config.
From the simulator on RH side, select your location and the device you want to configure
Triple click the button on the smoke sensor and click the configure button on the simulator, if you also have a tab with live logging you will be able to see if the configuration is sendt and received
So far I tried to un-pair and re-pair the sensors for 3 times. I do noted when I add the smoke sensor, the add things process alway not showing the sensor found but after I cancel it, I can find the sensor added.
I noted the z-wave finger print is different from the one in the handler, and that result in SmartThings already pair it as"z-wave sensor", and I’ve to manually change the device type in IDE.
Separately, I duplicated the Fibaro smoke sensor handler and updated the finger print, then SmartThings able to use the correct handler during the pairing, but I still can’t see the device info in the app.
This was probably causing the Configuration issue. If the device doesn’t pair correctly we can’t configure it correctly.
If you use the DTH with the updated fingerprint it should pair AND fingerprint correctly.
In the events list for the device or the hub do you see Secure Inclusion failures around the time of the pairing? Either way, it might be helpful to try pairing within 5-10 feet of the hub.
