You are not alone regarding a need to wet floor / carpet sensor. I’m one of you on wet dry alarm.
After years of craving with no positive respond or interest with Wyze I begin to analyze the underline agenda of monitor service provider, phone device developer, search engine provider in relation with the general public.
Security monitoring device is no different from smart phone, wearable devices and stationary device with internet access, directly or indirectly. They all can access to and also be accessed from Google, Apple and all other authorized agencies.
When it comes to product development the product and business manager has a priority list that define which come first vs last in favor to receive more or less subsidized on development cost or tax break.
Smart phone (now all has camera, microphone email account and data base) offers the most valuable intelligence gets a top priority, While wet dry device has little to no personal intelligence come out at bottom of list.
Be realistic, we give up / out our personal intelligence inadvertently or knowingly in return for little to free search engine and security monitoring service. That also indirectly cover fractional cost in our inexpensive monitoring device/camera.
Our best bet is to be innovate ourselves (or aid from others) with improvised device capable to trigger the associate alarm of our cameras.
