Water in hose timer battery compartment

I bought a new hose-end smart timer about two months ago. It went offline, and I noticed that the batteries were low. When removing the door to the battery compartment I found that it was flooded with water. Is this normal? Should I be concerned?

Also, how do I set the Rachio app to notify me when the batteries are running low? I looked in various places in the app but didn’t find anything.
