When I power off the Element bulb on the wall switch, when can I expect this bulb status change to show up in the App?

When the wall switch turns off a bulb, the bulb will normally show up in the individual bulb list as in "off" state in less than 10 seconds and as "offline" after at least 20 minutes. It takes time for the server to tell apart the "offline" from a temporary transient "off" state that can be caused by specific wall switch operations such as bulb resetting.

Note: While the bulbs are in "off" state, they will show up in the home screen as still being "online" and as active in the device list until they move into the "offline" state.

Bulbs will not be able to report "off" state to the server in the following scenarios:

1. The bulb will not send "off" state to the server if it is connected to the dimmer switch and is powered off from the dimmer. This is due to the fact that when being connected to a dimmer, the bulb may report the wrong state to the server due to the hardware setup.
2. If the bulb is powered on by the wall switch but quickly powered off again with no delay, it will not be able to report "off" state to the server. This is because the firmware on the bulb does not have enough time to initialize itself in order to send the "off" parameter.
3. If a bulb is powered off when it is in the middle of dimming enabled by the wall switch, the bulb may not have enough time to report the "off" state to the server as there is only enough power left on the bulb to send various dimming commands.

Even though the bulb will not be able to report "off" state in the above three scenarios and the server cannot detect them being "off" right away, the server will eventually be able to determine that the bulbs are indeed not online if it failed to receive any messages from the bulbs after 20 minutes and declare they to be "offline".
