Fibaro Smoke Battery low


my Fibaro smoke sensor had low battery, so I replaced it. But it is still showing low battery. Does not seem to report any battery level (when looking in the live events ). Anything I need to do to force this?

I had this. You were too quick at changing the battery. Remove the battery, give it 30 seconds to a minute then replace it. You should see the battery update after a few mins.
