Feature request - prevent from removing entities while rebooting HA

[anybody84]

AS-IS behavior:
Each time when I reboot HA and the printer is off most of the entities disappear from HA (except of binary_sensor.xxx_status). Then it looks bad in the frontend:

TO-BE idea:
It would maybe make more sense to keep the entities, just with 'unknown' or 'unavailable' state.

[AdmiralRaccoon]

Same here, I´m voting for that, too

[kersten-lohmeyer]

yeah, sorry but this behaviour is really odd. Please keep the entities. Also my printer is off most of the time so I just need the addon to update the ink levels once in a while. It should cache the last known ink level and not show unknown or unavailable.

In latest version of HA new offical IPP component added,
I stopped maintaining that component since that component (HP) is for specific API of HP while IPP is a standard cross-brand.

the only lack in the offical component is number of pages printed, job cancelled and scanned documents.

thanks for the input

For me this new IPP component don’t work.
With this component the state from my printer is always idle.

[anybody84]

Yep, same here. It's always idle, no matter what.

Fixed entities / device / device's area changing names is being reset after restart

Please check

So you're going to further maintain this component?

[elad-bar]

yap, after checking the IPP component for the last few 2 weeks, I found out it lacks of information that important to me, in addition, when the printer is off (power saving) lots of errors are being thrown to the log

[SeLLeRoNe]

If I may add something, the toner status entities shouldn't disappear when the printer is off (during HA reboot), they still should be created as the status ones, but with maybe unavailable value or something like that. (same goes for the printed pages)

[SeLLeRoNe]

Or maybe store the old value would be even better :P

Yesterday I released new version with restore state feature, can you check if it works for you?
thanks

[SeLLeRoNe]

I have just tried and now it doesn't "connect" to the printer anymore, the binary sensor sais it is connected but all the other sensors do not exists.

In the integration all the "components" are gone beside the binary sensor.

I am now tring to reinstall and re-add the printer.

I'll update with the outcome

[SeLLeRoNe]

I have this error in the logs:

2020-04-27 21:39:48 ERROR (MainThread) [custom_components.hpprinter.managers.entity_manager] Failed to update, step: Mark as created - binary_sensor -> HP LaserJet Pro CP1525NW Connectivity, Error: 'NoneType' object has no attribute 'disabled', Line: 201

And removing and adding back didn't fix, actually made it worse because now the integration is completely empty :D

[anybody84]

For me it works. I have set up an integration, then I've turned off the printer and restarted HA and I still have all the entities:

Thank you!

[SeLLeRoNe]

That's odd, are you using the latest version (released about 2hours ago)?

[kersten-lohmeyer]

Works as expected now, thanks a lot!

[SeLLeRoNe]

Ok last commit fixed my issue and now is working.
There is one thing I would suggest, the "sensor.cp1525nw_status" which define On/Off should really be a binary_sensor rather than a simple sensor :)

Thanks

[elad-bar]

the status is not On/Off, available options are:
On, Scanning, Copying, Printing, Cancelling Job, Idle, Off

[SeLLeRoNe]

Oh ok, didn't know that :D

Thanks for clarifying and for implementing the new functionality

I have the feeling the "On" shouldn't be in the sensor, it's fairly confusing :D
Instead, an "on" printer that is clearly doing nothing, should be set directly on Idle

[elad-bar]

Names are being takn from the printer's status, will try to find better name

[SeLLeRoNe]

I see, I find it confusing but I guess that's okay, no need for you to do any additional work, you did quite a lot already :)

Thanks
