Review: Very useful and highly accurate! - I added this to my WS1, put the WS1 in a watertight Pelican case, mounted as sensor externally, let it float on my pool and I have a wifi remote water temperature sensor! Well under 100$ total!
Review: functions as described - I deployed a test WS1 unit with this attachment and am VERY pleased!!! It is a must add-on accessory if the function is needed.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Very useful and highly accurate!
*by S***. on January 14, 2020*

I added this to my WS1, put the WS1 in a watertight Pelican case, mounted as sensor externally, let it float on my pool and I have a wifi remote water temperature sensor! Well under 100$ total!

### ⭐⭐⭐⭐⭐ functions as described
*by J***N on December 17, 2019*

I deployed a test WS1 unit with this attachment and am VERY pleased!!! It is a must add-on accessory if the function is needed.

### ⭐⭐⭐ Needs thinner cable
*by T***N on June 11, 2021*

The cable thickness allows air leakage when used in a standard household freezer with mag gasket. A thinner ( or flatter ) cable would reduce the issue. Still experimenting to find a cure for the air leak.
