Installation in the mailbox.mailbox drawing mailFi

1. The larger side of the device must be installed inside of the the mailbox to prevent it from being saturated with water. The smaller side will be installed on the door of the mailbox as it's components are water resistant. 

2. Alydi recommends using a temporary adhesive like blu-tack to position the sensor temporarily to get the alignment correct. The parts do not have to mate together perfectly, they can over-lap, under-lap be positioned sideways, as long as the blue light near the birds head illuminates momentarily when the parts are separated and once again when they come together, than you know you've got good placement. 

3.  Prep the surface. The surface of the sensor and the mailbox must be clean and free of any oils or loose particles, your mailFi came with an alcohol prep pad, it must be used to get a proper bond to the surface. 

4. The adhesive is Automotive Grade and will bond instantly and be completely cured after 72hrs. The adhesive will be 80% cured after the first 24hrs, 92% after 48hrs and 100% after 72hrs. 


If you don't want the notifications on your smart phone simply turn them off on the Smart Life app. Go to the settings tab for your sensor, use the pencil and paper icon in the upper left hand corner of the sensor status page for more information, firmware update, and removal of the sensor from Smart Life. (it can be re added).


Congratulations, you've made it, You're now receiving Alexa alerts when your mailbox door is activated. Why not add a smart bulb and turn on the porch light every time the mailbox opens?
