I think i found a bug regarding HSM. The issue has been reported several times in the community, but i have not found a fix until now. The only way to get the HSM working again is to restore a previous backup and many times you loose a lot of work.
The issue: HSM cannot be changed (dashboard or otherwise).
Bug: This happens when you access the HSM app. Even if you click Done before exit.
In my case i have no settings for the HSM app.
Update
I was using the HSM in an incorrect way. I was using RM rules to arm / disarm the HSM instead of it's own settings. BUT, the thing that tricked me was the absence of the arm/disarm rules in the HSM settings page. If you do not set at least one intrusion device, those rules do not appear.
I know that having intrusion devices is the necessary but at this moment i am still trying to figure out how to setup a reliable presence detection. Homekit geolocation works perfect but the range is too large and i need to use the door open/close sensor for confirmation before running any actions. But if i use the sensor both for presence confirmation and intrusion detection, i get an alert from HSM and it fails to arm home. This is an issue regarding presence detection, but it would be useful to have those settings available even if you do not set any intrusion rules.
