Easy setup with my SmartThings hub. Integrates with ST Home Monitor so you can automatically send push notifications/SMS to you. Seems more expensive than some other water leak sensors but if you have invested in an ST this is probably your best bet. If you want it to integrate with Alexa for voice prompts when they work, it can, but you have to go through a few extra steps to create virtual switches that sync to sensor status, and then Alexa can do routines based on that carry out. Not difficult, and there are plenty of guides online, but it's not exactly "plug and play".
