I don't know if 2050 is HSM, but that's the only thing that reports battery status. It's happening once every day since I enabled this feature in HSM a week and a half ago.
All alarms are triggering @ 100 (rule configured only below 50%) and it's always a different device. Just to be clear, the devices are at 100% so they should not be triggering HSM
Also, I don't know what the 7.5 is all about, it's not from me.
Go back to your past logs and find those errors again. The left blue “app:2050” is clickable, click it and then scroll back up as it will highlight which app it is.
I assumed you were trying to direct him to the app in question like I was with the URLs. I should have read your post more closely. Yes, it does show you which app it is but the purpose of the link is not to show you which app it is. It is to filter. The app being selected means it is filtering the log for just that app.
If you click the "Info" link in that screenshot it will actually navigate to the app (which is what I was trying to get him to do previous to your comment).
You could try to delete it and recreate it. Otherwise, do a support ticket or wait until Bruce replies here. He's been busy though. I haven't seen him around much the last few days.
Need to know what device is reporting 7.5 as a battery level. Battery levels should never be reported as decimal numbers. Is this from a built-in driver, or a custom one? I will look into the false reporting for 100, but have to wonder if it is related to the 7.5.
Also, please post the App Status page for this HSM custom rule.
