Lighthouse is a simple system monitor app for Sailfish OS/Jolla. It is intended to provide information about CPU, memory, network usage, running processes and eventually analytics to help find battery and network draining apps.

After the upgrade to SFOS 4 Lighthouse device controls does not work: neither reboot nor shutdown.

Xperia X, SFOS 4.

CPU load is not being displayed correctly on 3.1

I'm using glacial ambience with black elements but Lighthouse has still white icons. Thanks for your work.

By wallpaper you mean the theme on the screenshots? That's the one I got with my "cyan" other half when I got my original Jolla 1. I don't have it anymore on my new Sony Xperia X since I can't use the other half with it.

Sorry I got a bit busy, languages should all be accepted now. I'll be doing cleanup with unfinished translations soon tho (0% on transifex). If you need more time please ping me there.

Very well done! I simply like everything about it :-) Just wondering why it's called lighthouse-1.5.0-1.armv7hl, not harbour-lighthouse-1.5.0-1.armv7hl ;-)

Thanks a lot for this beauty!

Please can you help ?

I have an "old" version of lighthouse installed which I cannot remove or update - there is no version info in the "About" screen.

I can install the new version 1.4.1 alongside the old version but I'd like to be able to remove the old version.

Is there an OLD repo I need to enable which will pick up this old version to enable me to update it ?

Or is there an easier way (command line) to remove it ?



Almindor's picture

I'm wondering if this is because of me removing older RPM versions. I did this because it seems it sometimes cause people to not be able to update.

I'd try just removing the old version and maybe the repo too and the re-adding

This is my attempt #3 to post a comment here. Sorry if it's a dupe.

Thanks for all your efforts, I was waiting for a monitor like this one. Two suggestions:

- It would be more useful if memory usage showed "real" usage. I mean, without buffers/cache. The way it is now, it's going to be always close to 100%.

- Temperature display (may be optional) would be great too.

Again, thanks.

Hey, thanks for the suggestions.

People have been saying the same on the official Jolla store. I plan to add multi-value indicators for memory so the shared/cached portions are differentiated and the summay value will only show the real usage.

Added temp. display to my TODO list after I merge battery indicator from gilav

I just wanted to ask same question :) nice. Thanks for the app by the way :)

Great. Maybe a reboot function would be a good addition?

Almindor's picture

You mean phone reboot? That's behind root priviledges, but I can have a look how that's handled.

wickedsp1d3r's picture

Yes. There's an app called "SailfishReboot", but it would be nice that there was a single app that can handle phone rebooting as well when needed.

Mariusmssj's picture

I must say I do agree. With an app that gives information such as your having an option to reboot would be quite nice and not out of place.

Almindor's picture

added reboot and shutdown options (open phone controls from pull down menu in summary page)

Thank you :) much a appreciated.

Great app, any plans to put on github?

Almindor's picture

I do plan to publish in a short while. I want it to have process view first tho. Should be up in about a week.
