1. A computing device for monitoring a self-testing fire sensing device, comprising:
a memory; and
a processor configured to execute instructions stored in the memory to:
receive, from a self-testing fire sensing device, measurements of outputs of light-emitting diodes (LEDs) of the self-testing fire sensing device during operation of the self-testing fire sensing device;
determine when a deviation in the measured outputs of the LEDs of the self-testing fire sensing device meets or exceeds a threshold deviation amount;
determine an action to take on the self-testing fire sensing device upon determining the deviation in in the measured outputs of the LEDs meets or exceeds the threshold deviation amount; and
send a notification of the determined action to take on the self-testing fire sensing device to an additional computing device.
