Set up a rule:
When: [Leak sensor name] Detects a Leak
Action: [Camer Name] Turn on the Siren
See an example here:
Amazon/Alexa doesn’t currently support Leak Sensors as triggers, so we need Alexa to add that support first. There are some complex advanced work arounds using things like Tasker, and maybe IFTTT Where you can push webhooks to Google or Alexa to broadcast things to smart speakers, but this is beyond most people’s capabilities to do. None of that is Wyze’s fault though, the big boys just don’t support leak sensor routines yet. Wyze does natively allow you to create your own routines for a siren through, so that helps. Other people also make lights flash when a leak happens too.
