Setting Up WiFi and Obtaining a
Registration Code
The Smart Si thermostat uses your home WiFi
network to connect to the Internet. First, enable
WiFi on the Smart Si thermostat (see instructions
to the right).
The Smart Si thermostat will display a list of
available networks, along with an indication of
the signal strength (the more bars, the better)
and whether encryption is used.
If your home network is not listed, or if the signal
strength is very low, try adjusting the antenna
on your wireless router. If that doesn’t improve
the signal, try moving your router closer to the
Smart Si thermostat.
Once your network has been detected, select it
from the list. If the network is encrypted, you will
be asked to enter a password for that network.
This is the password you created when the
wireless router was rst set up.
After you provide the password, your Smart Si
thermostat will automatically connect to the
Internet. A chain link on the screen indicates you
have established a connection with the ecobee
web servers.
Write down the registration code as you will
need it when conguring your Web Portal
account. You can leave the code displayed on
the screen while you continue with the next
step.
To set up WiFi:
From the Home screen,
press MENU.
Select Register Thermostat.
Select Continue.
Select WiFi Settings.
Select WiFi Radio ▶
Enabled.
Select your network from
the list.
If prompted, enter your
network password.
