Battery level for entry sensors

@simplisafe_admin​ This is really a huge improvement and needs to be better communicated. Worthy of sending an email to all users.

The battery level on the app is not reliable enough to disreagrd problems with communication, so if there is any weakness, you can still be at risk. I checked the batteries on 2 sensors that were showing lower communication signal by using a volt meter and they read 3.0 and 2.9 VDC. The battery level on the app read "fine". This affected the sensor communication but not the battery indicator on the app. and still blink blue. It can be misleading when trouble shooting. I changed them out. A good battery will read above 3.0 VDC. At or below 3.0 and you can be at risk. Below 1.5 VDC for the AA battery in the key pad will give you issues. All you need is 1 low one out of the 4 to give you an issue. The whole system still functions but check or change your batteries if there is any indication of a communication issue.
