Video Doorbell Pro Voltage Dropping?

My voltage is now down to 3925 since yesterday. It continues to drop each day, and despite being told to not worry as well, I am worried I’ll have problems.

Again, so far so good–the DB Pro continues to work fine…for now.

As I wrote in my above post: I found it odd that after my router being offline for 20 or so minutes last Friday the mV on the Pro shot back up to over 4,000 again once I brought my network back up–all without me doing anything at all to the doorbell.

If I do end up needing to reset it, I’m thinking I could just unplug mine for a minute and plug it back in since my entire doorbell setup consists of the DB Pro, and an AC adapter. No electronic or mechanical chime, kit–nothing.
