Intermittent buzzer beeps from T1000-E despite silencing

[hickford]

Hi. I silenced my T1000-E using the (undocumented) triple press of the button. However it still beeps intermittently (when not charging), perhaps to indicate low battery.

Unfortunately you can't silence the T1000-E in the MeshCore app.

Steps to reproduce

1. Triple press button to silence T1000-E
2. Disconnect charging cable
3. Go to bed

Expected

T1000-E is completely silent all night long.

What actually happens

After several hours, the T1000-E buzzer beeps around every 10 minutes.
