HSM does not arm

From the dashboard, I tried disarm all and it worked. When I try to "Arm" or "Arm all", it does not work. No change in the status

Did you ever solve this? I have the same problem

No. I eventually moved to HomeAssistant

Within the HSM app did you select devices? If devices aren’t selected for the intrusion away/home/night you are trying to arm, it doesn’t work.
