If you can browse the Internet from the computer / device where the WiseMo Host is installed, then you can use myCloud connectivity to reach your computer / device. (The Host will use port 80 and 443).
Sometimes firewalls are configured to block browsing the Internet. In such situations, you can still use myCloud, with a small configuration change to the Host configuration.
The Host default setting for myCloud connectivity, where it uses port 80 is: http://mycloud.wisemo.com/cm
As an alternative, you can change this setting, so it uses port 1970 instead of port 80.
Your firewall must then permit out-going traffic on port 1970.
Edit the myCloud communication profile on the Host and change the myCloud Service URL setting to http://mycloud.wisemo.com:1970/cm
