Newbie question: dealing with a new sensor

I’m brand new to HA (Hassio on RPi3), and I’m struggling to figure out how to deal with a new sensor. I’ve got the Aeotec Z-Stick Gen5 and an Ecolink Z-wave door and magnet sensor. I’ve got the two connected, and I can see the “Sensor” state change when I move the magnet, which is good. What I’m struggling with is (a) giving the sensor a more descriptive name, and (b) hiding the other Ecolink Unknown: type... and Alarm Level stuff. As far as I know this is just a 1/0 sensor, so I don’t need 6 different entries on my states menu.

For (a), I tried going to Configuration --> Z-wave --> Select the node (Node:3 Probe) and renaming the node, but nothing happens there.

For (b), I went through the “Entities of this node” and checked “Exclude this entity from Home Assistant,” but they’re still showing up on the list of states.

Is there something I’m supposed to add to configuration.yaml to get the sensor to have a more descriptive name? Once I get that, then I’ll work on figuring out how to automate stuff with the sensor. Any tips there are appreciated as well.

You have to restart Home Assistant for the change of name to be applied. This may also apply to the excluded entities.

There’s also friendly names, which you can set via customize.yaml
