So you have a way to get temperatur. That’s a start. For Battery, you might need to wait a while until the sensor first reports the level.
For Tamper, i noticed that the example is missing the “%s”! maybe adding this could get you one step further (“Water-Sensor: Tamper [%s]”)
Then the actual flood alarm would remain. Being the main purpose of the device it would be a killer if it didn’t work. Maybe reading through this: Zwave binding / FGFS101 Flood Sensor issues - #15 by chris an this: Collection of working z-wave configs - #8 by naturalblaze
could help you finding the right settings…
By the way: What OH Version /ZWave binding version are you using?
