Access via web browser

Via FENECON portal

In addition to our app for Android and iOS, you can also access FENECON Online Monitoring via your browser:

Go to FENECON Website and click on the yellow "FEMS-Login" button in the upper right corner to log in with your login data. You will then be redirected to the monitoring.

Alternatively, you can also use this link to log in directly.

Create a shortcut to the login page on your desktop for faster access. This is also possible on mobile devices.

Offline/local access

Monitoring can also be used purely locally ("offline operation"). This form of access is useful, for example, in the event of an internet failure if the FENECON portal cannot be reached.

Instructions — Local access

To do this, enter the IP address of the FEMS in the browser. By default, the FEMS automatically obtains an IP address via DHCP. You can view this via the user interface of your router.

The prerequisite for using local monitoring is that the respective device (e. g. notebook, PC, smartphone) and your FEMS share the same network.

Table 2. Instructions — Local access via laptop
First, compound the laptop with the LAN port of the FEMS box.
Under Windows: Open the Control Panel and then select Network and Internet.
Then click on Network and Sharing Center.
Click on Change adapter settings in the side menu.
Right-click on the corresponding icon to open the properties of this LAN compound and select IPv4. The following window opens:
At this point, place the laptop in the same number range as the FEMS.
Now open any browser and enter the IP address of the FEMS in the address line.
The following login window should open after the entry. The password for guest access (guest) is stored by default. To be able to use the rights as system owner as via portal access, use owner as password. After entering the password, you can access local monitoring by clicking on the Login button.
The local FENECON Monitoring opens and you can use it to view your system data.

Firewall and target addresses

The following services are active on the FEMS and require an internet connection to the respective target addresses:

Table 3. Firewall and target addresses
Service	Destination Address(es)	Destination Port
DNS	(IP address of the DHCP-assigned DNS server)	53 (DNS)
Online Monitoring	144.76.42.217 (fenecon.de) 162.55.102.78 (www1.fenecon.de)	443 (HTTPS)
Time Synchronization	144.76.42.217 (fenecon.de)	123 (NTP)
Operating System Package Updates	144.76.42.217 (deb.fenecon.de)	80 (HTTP)
Remote Maintenance	168.119.5.99 (remote-service.fenecon.de)	2222
FENECON Service	185.145.190.0/24

If you have problems with any of these steps, please check the port release of the router or contact service@fenecon.de.

Switching to the new design

Die Umstellung auf das neue Benutzerinterface (UI) wird ab FEMS-Version 2026.9.1 funktional vollumfänglich zur Verfügung gestellt.

Wir empfehlen daher ein Update auf die aktuellste FEMS-Version. Ansonsten können App-Einstellungen eingeschränkt im Neuen Design zu Verfügung stehen.

To switch to the new design, follow these steps:

Navigieren Sie über das Hauptmenü der FENECON App zu den Account-Einstellungen (Account-Name).

Check the box next to "New UI" in the lower-right corner.

If you switch from the previous design, you can disable the new design at any time by unchecking the box next to New UI.
Like other account settings—e. g. language—the new design is specific to each user.
The final switch to the new design will take place automatically at a later date.

== Access

After logging in — if several FEMS are assigned to the account — you will see a list of FEMS. If there are more than five FEMS, a search bar also appears so that you can find the desired FEMS more quickly. Clicking on the respective FEMS calls up the monitoring of the system.

If only one FEMS is assigned to the account, you will be redirected directly to the FEMS Cockpit:

== FAQ & Troubleshooting

When the FENECON Energy Management System (FEMS) is offline, the generated data is saved locally on the electrical energy storage system. Once the "Online" status has been restored, this data can be forwarded to Online Monitoring within a short period of time. The duration of the forwarding depends primarily on the amount of data and requires a constant internet connection. We would like to point out that data with a corresponding priority will be forwarded, which includes the data that can be seen in the usual Online Monitoring.

Slight errors may occur when data is forwarded. The reason for this may be that data from external devices has already been forwarded to our system incompletely. Correcting data involves a great deal of effort, as FENECON has no information about potentially incorrect data transmission, on which calculations are based and the extent of the impact cannot be precisely determined. Furthermore, with regard to data transmission and processing, we would like to point out that no calibrated meters have been installed on FENECON devices to date and that even small deviations can occur in split-core current transformer measurements. Therefore, this measured data does not fulfill any control or billing requirements. Therefore, the data on which the individual values of the forwarding are based can neither be identified as incorrect nor corrected accordingly. For this reason, FENECON assumes no responsibility at this point with regard to the processing of a data correction in the forwarding.
