Hardware reset button - Almond+ 2014
From SecuriWiki
The hardware reset button is located at the top left hand side of the Almond+ in one of the air vent holes and has a small "recycle" logo next to it.
You need to press and hold the reset button for 10 seconds to perform a factory reset of the Almond+.
Note: A factory reset will clear all settings on your Almond+, but will not remove connected sensors or your Almond cloud account.
