I have an Ecolink Water Leak sensor which is shown as connected (as a generic z-wave water sensor) under devices and is selected under the Amazon Echo Skill. However, I have been unable to add it to Alexa. Has anyone made this work with Alexa?
I don't believe Leak sensors are a device you can add to Alexa.
I assume you want Alexa to announce a leak? It can be done but it will take a bit of setup.
One way would be to have a virtual switch in HE trigger a routine in Alexa.
