What do I need to install Floodie? – Alert Labs

You only need two things to set-up your Floodie companion sensor:

An orange Alert Labs sensor
An orange Alert Labs sensor, such as the Flowie water sensor, needs to be installed and operating with a good cellular signal before you install your Floodie. Floodie is designed as a companion, so it will need to be installed within range (400' or 6 stories) of the orange sensor in order to connect.
A computer, tablet, or mobile phone
In order to register your Floodie, you’ll need access to the internet, and the serial number of the sensor. The serial number is printed on the bottom of the device itself, on the box it came in, and on the removable installation sticker.
