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: Doing a factory reset will make the Almond+ forget all settings, including connected sensors and Almond cloud data, so please make sure you've disconnected your Almond+ from the cloud and removed all sensors before doing a hardware reset.
