The Komfovent device communicates with other devices using two Port numbers: using Port 80 with the
browser and Port 502 with Komfovent home app. The communication protocol type is TCP. This is how it looks
schematically:
84.15.200.253
PORT: 4502
WIFI/GSM
PORT: 4080
In the Komfovent app,
enter the router IP address:
84.15.200.253 and the Port
number created in the route:
4502
In the WEB browser enter the
router IP address and the Port
number created in the route in
the following format:
http://84.15.200.253:4080

You can create external, i.e. (Start) Port numbers based on your preferences. It is important to remember or
write them down. You must specify them for connection to the external devices. Internal (End) Port numbers of
devices are usually indicated by the manufacturer, otherwise they should be determined by yourself.
Let’s have a look at what’s going on in the picture above. The phone 1, using the Komfovent home app,
wirelessly (GSM/WiFi) connects to the Internet by specifying the router address 84.15.200.253 and the Port
number, for example: 4502. The router receives the request, and using its settings creates a tunnel for data
transfer to the air handling unit with an IP address on the local area network 192.168.0.60 and Port number 502.
In this way, the devices on the Internet can connect to, and control the air handling unit.
When connecting through the browser, on the device’s address bar, enter the router address and specify
the Port number in the following format: http:// 84.15.200.253:4080. We will access the air handling unit, which
is within the router’s local area network.
