From your screenshots I see nothing that’s not Ok, and I’ve also looked through the Diagnostics Report you sent but can’t find anything their either.
So, it’s hard to determine what’s going on, but let’s try to fix it.
Can you please set an Alarm Delay of 30 seconds and select Delay on the Hal Upstairs sensor?
Next, make sure Hal Upstairs is not detecting motion and set the Surveillance Mode to either Armed or Partially Armed. Next, Do a little dance in front of the sensor, wait a couple of seconds and set the Surveillance Mode to Disarmed.
Please go into Heimdalls settings and send a new Diagnostics Report.
To disable the Alarm Delay you just have to remove Delay from Hal Upstairs, there is no need to set the Alarm Delay value to 0.
You can then do the test sequence again, see what happens and send me a new Diagnostics Report.
Can you please add the time you started the tests in the remarks in the Diagnostics Report, that will make it a lot easier for me to find the part of the report that is relevant.
