So far I have been using zwave2mqtt to add my zwave devices and also use that interface to name them. I find that the friendly name I give them there does not always carry over into other areas of HA.
I’m going to be excluding all of my devices and readding them over the weekend to change from S2 to no security for performance reasons and wanted to see if there is a better method of naming devices this time around.
After inclusion the first step I do is renaming the whole device, before I use it anyhow. That way all entities will contain the chosen name.
But, do not rename this way after you already included the device in some automations or scripts, as they will stop function. Rename directly as the first step after including the device in the Z-wave network.
