Notification language follows your phone's language at login. If multiple people use the same account or you log in from different phones, language may change. To set it manually: log in to https://omatsivut.sectoralarm.fi/login, go to Account, choose the language. Consider creating separate accounts for personal codes, language, and activity logs.

Takes long time to load that is almost unusable. Unacceptable. The functionality in the app is average. There are no smart home integrations available and the UI is basic. The big problem is it takes ages (up to a few minutes) to load the interface that allows you to arm or disarm. Keep in mind we are paying around 50 euros a month for the service and still the app that comes with it is way under the standard of other apps. This is so bad we are considering canceling the service.

Still can not create and activate one-day codes for entry. When trying to activate them (using valid password and waiting an eternity for sync), the code is still listed as "inactive". Everything takes an eternity. If you want to quickly open the app and disable the alarm, you first have to wait for it to connect to the alarm and check the status. There is no option to skip this and simply order the alarm to either turn off or stay off. There is no way to auto generate keys and copy the code.
