How does the Roost Smart
Leak Detector detect water?
1. Audible alarm sounds when both silver ring contacts
on bottom of Leak Detector get wet
2. Device connects to Roost Cloud and audible
alarm sent to user’s smartphone indicating leak or
presence of water
3. Customer needs to dry off silver ring
contacts, especially the space between them,
to silence the alarm.
The device also checks temperature and humidity via integrated sensor

CONFIDENTIAL
The detector is not always
connected to Wi-Fi
• The Roost Smart Leak Detector checks in with
the Roost Cloud once every 24 hours.
• Except the first 24 hours (8 check ins)
• Otherwise it is in a state of “watchful waiting”
for leaks, or out-of-range temperature or
humidity
• When the device senses water, or an out-ofrange temperature or humidity, it wakes up
and connects to the Roost Cloud, then sends a
notification to the owner’s smartphone

CONFIDENTIAL
What happens when a customer
sets up a Leak Detector?
STEP 1: User enters
name, email, phone,
device name in
Roost app
STEP 2: From phone App gets:
1. SSID (name) of Access Point
(or Wi-Fi router)
2. SSID PW entered in app
3. User info
Token
Leak Detector listens via a
Piezo transducer (sound)
Leak Detector connects to cloud and passes token back
STEP 3: App makes phone make
“set up sound”
(encoded audio) with token
Token
Cloud connects user account w/ battery

– Especially when away
– Monitoring places not in daily view
• Prevent damage to personal property
• Avoid hassle associated with a water leak
– Contractors in home
– Disruption to schedule
– Time away from regular activities

•
•
•
•
Hot water heater (especially if > 8 years old)
Kitchen sink
Toilets
Refrigerator (ice maker)
Dishwasher
Washing machine

After set up:
What does the Cloud do?
The Cloud initiates notifications to users
• Alarm events
• Device detects, connects to cloud, sends alert
• Cloud sends push notification to (Apple, Google) push servers
(cellular/Wi-Fi) for number
• User opens app, app connects, reads status from cloud
• In app – Device power status (low, critical)
• In app – Wi-Fi signal strength
• In app – Device check-in status
• In app – Device temperature, humidity
21
CONFIDENTIAL
Check in with the Cloud
The device initiates ALL communication
It has an internal clock—Every 24 hours it “wakes
up” and checks in with the cloud.
•
•
•
•
•
Cloud records device checked in and data from device.
DEVICE checks – is there anything for me? Firmware update?
If there is a FW update, device initiates download
Cloud CANNOT initiate contact with device.
Cloud tells device when to check in next.
“Hi, I’m sensor ID # (tied to MAC address).
My power is {{z}} mV. My RSSI is -55. I’m connected to {{SSID name}}, temperature
{{x}}, humidity {{y}}. Got anything for me?”

What is a 2.4 GHz Wi-Fi band?
• Modern Wi-Fi routers broadcast
on different frequencies
– 2.4 GHz
• Good coverage range, deals with
physical obstacles well (walls, etc.)
– 5 GHz
• Faster speed, not as much range,
physical obstacles can be more of a
problem
