Door closer diagnostics system

A method, comprising:

• generating, by at least one sensor, motion data indicative of motion of a door having a door closer as the door is moved from an open position to a closed position;
• analyzing the motion data to determine a duration the door was in each of a plurality of door movement zones between the open position and the closed position;
• determining at least one adjustment to the door closer for a successful installation of the door closer based on the duration the door was in each of the plurality of door movement zones;
• and
• displaying at least one installation instruction corresponding with the at least one adjustment on a graphical user interface of a mobile device;
• wherein the plurality of door movement zones comprises a main zone and a latch zone;
• wherein determining the at least one adjustment to the door closer comprises determining to loosen a main valve of the door closer in response to determining the duration the door was in the main zone is greater than a first threshold time;
• wherein determining the at least one adjustment to the door closer comprises determining to tighten the main valve in response to determining the duration the door was in the main zone is less than a second threshold time, wherein the first threshold time is greater than the second threshold time;
• wherein determining the at least one adjustment to the door closer comprises determining to loosen a latch valve of the door closer in response to determining the duration the door was in the latch zone is greater than a third threshold time;
• and
• wherein determining the at least one adjustment to the door closer comprises determining to tighten the latch valve in response to determining the duration the door was in the latch zone is less than a fourth threshold time, wherein each of the third threshold time and the fourth threshold time is based on the duration the door was in the main zone.

• wherein determining the at least one adjustment to the door closer comprises determining the at least one adjustment to the door closer based on at least one user-selected installation setting for the door closer;
• and
• wherein the method further comprises receiving, by the mobile device, a user selection of the at least one user-selected installation setting for the door closer.
