Review: 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: The Ubibot unit is brilliant, sadly the USB connection to external probe isn't. 1st one broke not long after arriving, 2nd one already show signs of breaking. Disappointing as the rest is great
