Thank you! All fixed.
Is there a way to use Fully to shut down a Fire tablet? I see there’s a button to restart the device but it would be nice to shut it down when my alarm goes into vacation mode.
restart is to restart fully, not the device.
there is no (easy) way to shutdown or restart a fire as far as i know.
if there is i would love to hear it, but then its added recently in fully.
Hi There, I read back in this thread about people having issues with FKB (Lenovo tablet) slowing down over time. I have this happening, if I refresh then clicks etc result in quick changes (e.g. turn on/off light). But over time this seems to get slower and slower. Using the same dashboard on my iPad everything is quick.
Someone recommended removing the logger in Default Config, but that seems like I would be removing other things as well? Any ideas?
Nightly reboot.
I have been using FKB for 2 years but last weekend I for the first time tried the Screensaver functions. One thing that I haven’t found a setting or solution for yet is how to randomize a list of YouTube clips every time the screensaver is activated. Any pointer on the direction? Many thanks.
I see others have also mentioned memory use and seem to have narrowed it down to surfaceflinger
(Android’s window manger).
I have my tablets set to restart daily (9:45am) but they seem to drop down in free memory and eventually become unresponsive (dotted line where the tablet is no longer responding to the FKB API) during the day.

The tablets (all FireHD* 2017 models) except one without the memory leak show up as (eg tablet-study):

I’m wondering if this is some interaction between Fully Kiosk Browser and the Lineage build for the two platforms?
To track this down further I ran a dumpsys memory at the start and then after a while of running to see what was expanding.

It seems like the surfaceflinger process is responsible. But I’m at a loss on how to debug further. It would be useful to know if others see the same behavior? I found graphing the output of FKB’s memory use over 24h a useful way to watch this.
Any ideas on what I could look at next?
are you installed LineageOs on FireHD10?
how did you do that?!
mine is 2021 version, I’d like to install a clean Android version
Hello together,
I would like to control my fully browser and I would like to do this via key & value.
But I do not find the available keys. Can somebody help me please to find them?!
Refer also to Fully Kiosk Browser - Home Assistant (home-assistant.io) “The configuration parameter key. The list of available keys can be found in the Fully Kiosk Browser remote admin panel by clicking the Show keys button.” but unfortunately I do not know where to look at
Many many thanks!
I wasn’t aware of this guidance about the ‘Show Keys’ button, and like you can’t find it in the device admin panel.
Assuming I’ve understood you correctly and you want to be using commands sent via the device’s REST API, I’ve always used this part of the FKB guidance to work out the individual keys.
How do you figured out the individual keys?
It is really frustrating… I see in the docu the following and do not know which keys are available…
You’re right, that is not helpful. But I think I found it.
Go to your device admin panel, and click on the hamburger menu top left:
Choose ‘Settings’:
Choose any setting category, e.g ‘Web Content Settings’:
Scroll down to the bottom of the page, and there is the fabled ‘Show Keys’ button:
Thanks for prmpting me to do this - I learnt something new today
Ahh cool! How can I access the Fully Remote Admin? I access my Fully Devices only via local connection, they are not in the Cloud. I hope this works here as well… Many thanks!!
Yeah, this is all local. I don’t subscribe to the FK Cloud thingy.
Go to HA Settings > Devices & Services. Then click on the Fully Kiosk integration:
From there, choose your device from the list:
You should have a link to the Admin Panel for the device (‘VISIT’):
Of course, this assumes you’ve enabled ‘Remote Admininistration (PLUS)’ in the FKB settings on the device itself, and have a paid licence, but I’m guessing you’re asking here because you’ve already done all that.
Ahhhh, now finally!!! Many many thanks!!!
I wish you a really nice weekend!!!
Not sure if anyone is having this issue, but for some reason, Fully is not staying in the foreground on an Amazon Fire Tablet 10. When I restart or manually set ‘Bring to forground’ it swiches back to the Amazon launcher after a few seconds. Thoughts?
I remember seeing a different version of FKB for Fire tablets. Maybe try using that one to see if it solves your problem.
I have 12 fire tablets throughout the house running the same version. This is the only one that seems to be putting the fire launcher in front of fkb. Thoughts?
its exactly 30 secs.
sounds like a setting, maybe screensaver or something alike.
