You need to understand how battery powered devices work.
They are always monitoring whatever they are supposed to. Water, door, window, etc. But they do not bother to transmit until they sense a change. This is to save battery as the radios take quite some power.
But most of them are set to push a status update on some interval. Some 3600 seconds, some 14400 seconds. Some you can program. This is to preserve battery and it’s not until this is sent you get all the status updated as to neighbors, battery, etc.
When you wet-finger the sensor you are causing it to wake up and send what it’s made to sense. But you do not get the full status with that update.
So just because they can take time to update initially they are likely all ok and just waiting for the next update time.
When sleeping you can not wake the device from the controller side; as it’s not got the radio powered to hear a request. It’s running radio silent until it has a reason to wake up (due to sensing or due to wakeup interval)
**Note: some Zwave + devices change this somewhat.
