Entry Sensor V2 low battery

I just installed my system two days ago and now after downloading new firmware tonight my front door entry sensor says it has a low battery. Anyone else having issues with low battery tonight?

Welcome to the forum @jkreamer!

I have checked all 12 of my V2 contact sensors on the firmware and none are showing a low battery notification. They have been deployed since 4/21 with the original batteries.

Have you tried replacing the battery and are still getting the lower power notification? Could be that the battery has just sat a bit and went low on power in storage/on the shelf.
