Hi,
Let’s see what’s happening here, this shouldn’t be to hard to find.
First off, Heimdall can not arm itself, it will always be caused by of either a flow or a person performing an action. Since your log shows the Surveillance Mode is changed by a flow, let’s focus on that.
Easiest would be to go to Apps (in the Homey Mobile app) and select Heimdall.
This will show you all flows that are somehow connected to Heimdall
Please review all your flows shown here.
Another method would be to disable the Heimdall app and go through your flows, all flows somehow connected to Heimdall wil show a warning
Please review all flows showing a warning.
Hope that helps!
