As you have probably already found here in the forum, there are many who are still having ongoing issues with the HMS Sense Hub as a result of the last two Firmware updates.
My first course of action would be a soft reset. Unplug the hub from power so tells you it is running on battery and press the reset button until the lights flash. Let it go thru the setup protocol and light show, plug it back in and then wait for it to reconnect to all the sensors…give it ample time.
Then reopen the app and verify that the hub is connected, FW is correct, sensors are listed, tones are on, etc. Verify everything.
Place it in test mode and start arming and alarming everything. Document the issues so you can submit logs if it fails.
Not promising anything. I had to do this with mine after the update. Now, I don’t update it or touch it for fear it will puke.
