I’m tired tonight, but hopefully someone else can explain the Z wave tweaker, which is a custom device type handler. By temporarily assigning the device to the tweaker, you’ll be able to reconfigure any of the parameters. Then once you have reconfigured them, you will reassign it to its original device type handler and The parameters will remain the way you set them with the Tweaker.
The original FAQ information in this thread refers to the original smartthings architecture, which was in place through the end of 2022 and a little beyond. Custom code was written in the groovy programming language and ran in the smartthings cloud.
As of May 2023, you can no longer add new Groovy DTH‘s or smartapps to your smartthings account. So if you came here because of a link in an old forum thread, or on another site, I’m afraid the Groovy information is no longer usable.
All of this was replaced by a new architecture. Cloud to cloud integrations use the smartthings API. Hub connected devices, mostly Zigbee and zwave, now use “Edge Drivers,” written in the LUA programming language. Here’s the official announcement on those:

This is a device handler to assist with interrogating and tweaking Z-Wave devices. It’s designed for end-users who want to tweak their devices and for developers who want to quickly discover and report the functionality of new devices. It is intended to temporarily replace a device’s normal device handler.
