[bug] Remote activates standby when removed from dock

Is there an existing issue for this?

Description

I have repeatedly noticed that the remote has to reconnect to the wifi immediately after it has been removed from the dock. I previously thought that it could be due to my router, but on closer analysis of the log, I noticed that the remote switches to standby mode the moment it is removed from the dock, which of course makes no sense.
Unfortunately, this cannot always be reproduced and it is not due to how long the remote has been in the dock. It has also occurred after just 20 minutes.

How to Reproduce

1. Make sure the remote is not in standby mode
2. Place it in the dock
3. Wait
4. Remove the remote from the dock

Expected behavior

The remote shouldn't switch to standby when removed from the dock

System version

1.7.7

What part of the system affected by the problem?

Still a problem with 1.7.12. Could this be reproduced or is there any (maybe also hardware related) explanation for this behaviour?

I haven't experienced that behaviour yet, but the remote definitely shouldn't go into standby mode immediately after removing it from the dock. But your logs clearly show that standby is initiated less than 500ms after removing it from the dock.
The main "remote-is-active" input sources to prevent standby are the accelerometer, user inputs and if it's in the charger. If the accelerometer were damage, you would most likely have noticed it. Or you got a Jedi hand, not triggering it while taking it out of the dock :-)

I will double check the standby logic. My assumption is that this is a race condition in handling the power-mode inputs.

[zehnm]

A workaround is included in the next release which prevents standby right after taking the remote out of the charger: standby is blocked for 5 seconds which gives plenty of time for an input event to activate normal operation mode (turning screen on etc).

Otherwise we can classify the charger-disconnect event as an activity event. This would immediately put the remote into normal operation mode. The only "downside" would be for special use cases like powering the dock with a USB-C POE splitter and turning off power on a schedule. Then the screen would turn on, instead or remaining dark.

The workaround is included in beta 1.7.13 and I'll close this issue once a public release is out. If it still happens, please reopen the issue and I'll implement the alternative solution.

Part of 1.7.14

@zehnm Unfortunately, the error still occurs with 1.7.14. I can't reopen this issue as you closed it as a maintainer

I should perhaps add that I set the accelerometer sensitivity to the lowest value on the remote.
