This discussion was created from the release v1.6.0.

One thing I would like to verify on this pre-release is memory consumption (e.g. overnight).

When the display turns OFF, TouchKio now switches the dashboard to a static idle page after ~10 minutes. The idea is that Chromium stops painting Lovelace while the screen is unused, so RAM should stay flat until morning compared to previous versions.

Please leave a device running and watch the Memory Usage MQTT sensor in Home Assistant (a history graph is enough). Useful to compare:

• Display OFF all night (idle page active, default)
• Display ON all night (dashboard still rendering)

RAM usage should not climb as much as before on an OFF screen. This seems to be a HA rendering issue, on other simple websites memory usage stays constant.

The static idle page renders a Moon symbol, but should never be visible. You may see the idle screen when connecting via VNC, a click or display ON will bring you back to the main view.

Hi.
Since the last update my screen always shows the mentioned moon after a while. It's like a standby mode.
But my hdmi display has no touch capabilities and is only for viewing, I cannot get this deactivated.

Any way to reactivate the "old" bevaviour without the "moon mode"?

(I use a Pi 3+, diplay activation via MQTT is not possible there if that would be the way)

Thanks for the great touchkio. I really love it ;)

Could you please post your first few lines of the log:

head -n 100 ~/.config/touchkio/logs/main.log

Yes, you can disable it by using --app-disable=web_idle or adding this to the Arguments.json.

"app_disable": [
  "web_idle"
]

Thanks.

And I just added

and system is rebooting

First of all thanks for this excellent app!

I would love to test this as my RBPi5 crashes reproducible after a few hours of operation and I see a constant memory increase.

I ran the installation script yesterday but it seems to deploy V1.5.2 instead of the new 1.6.0. Is there any extra command to add to select the version to be installed?

[leukipp]

bash <(wget -qO- https://raw.githubusercontent.com/leukipp/touchkio/main/install.sh) update early

[Kugelfang666]

Cool, that worked, I’ll monitor behavior and come back here

[Kugelfang666]

Unfortunately I have to confirm that there still seems to be an issue with the memory congestion.

Between September 21st and 25th my raspberry was running and TouchKio was just idle on the HA login screen.

In the 25th I logged in and as you see the memory is beginning to get filled.

When TouchKio crashed, I rebooted the pi and immediately logged in. One can see the memory again rising.
