TECHNIQUES FOR FIRMWARE UPDATES WITH ACCESSORIES
Techniques are provided for updating firmware of an accessory device. An accessory development kit of the accessory device can communicate with an accessory update daemon using a home management daemon of a controller device. Based at least in part on a firmware update policy of the accessory device, the accessory update daemon will check for firmware updates. When firmware updates are available, the accessory update daemon can instruct the home management daemon to stage the update. The home management daemon will notify the accessory development kit to be in a stage mode. The accessory update daemon will download the firmware update and send the firmware update to the accessory development kit of the accessory device using an interface for the secure channel provided by the home management daemon. The accessory device can be a third party accessory device that does not have its own firmware updating application.

determining, based at least in part on the detected signal, whether the accessory device is in a state for applying the first update; and
in response to determining that the accessory device is in a state for applying the first update, applying the first update to the accessory device.
10 . The method according to claim 4 , wherein in response to determining that the update category of the accessory device is the time based update category, the applying the first update to the accessory device based at least in part on one or more rules associated with the update category of the accessory device comprises:
determining a time associated with the accessory device for applying the first update, wherein the time is a predetermined time period for applying the first update; and
applying the first update to the accessory device based at least in part on the time associated with the accessory device.
11 . The method according to claim 1 , wherein the accessory device is available for applying the first update if the accessory device has sufficient processing capacity to install the first update.
12 . The method according to claim 11 , wherein the processing capacity comprises battery capacity and memory capacity for applying the first update.
13 . The method according to claim 1 , wherein the first update comprises an accessory device firmware update.
14 . The method according to claim 1 , wherein the updating the accessory device is performed automatically by the controller device without user intervention.
15 . The method according to claim 1 , wherein the one or more rules comprises a policy associated with the accessory device.
