Many thanks, That's clear but unfortunatly my question was not !
In fact I'm trying to recover switches created by "trap events from remotes and sensors" ...
My remote (minimote) doesn't appear in z-way network/z-way devices (it appears only in the expert UI but not in smarthome).
I'm able to check the status like this :
http://rapberry_ip:8083/JS/Run/controller.devices.get("ZWayVDev_zway_Remote_22-0-0").get("permanently_hidden")
The answer is : true
But I didn't find how to change the value to : false ...
