I started out with openhabian, and a very useful tool that came with it is frontail (github).
It hosts a webserver on port 9001 and shows logs. Basically it is a tail -f
with a UI.
I embedded the frontail webpage in my habpanel, but wanted to change the css so it would integrate nicely.
This was quite a search, because it wasn’t documented anywhere and I couldn’t find anything about it on google.
I added it to the README.md and created a pull request on github, but in the meantime this is the way to go:
The .css files frontail uses, are located at /usr/lib/node_modules/frontail/web/assets/styles
.
If for any reason your system uses a different location, I found it out by doing a sudo find / -iname styles/dark.css
You could edit the already included default.css
, dark.css
or openhab.css
, but a better option is to create a new .css file, i.e. custom.css
and let it inherit from one of the 3 other .css files using @import 'default.css';
, @import 'dark.css';
or @import 'openhab.css';
at the top of your new file.
This way you only have to add/override the style definitions you want.
You can tell frontail which theme to use on start with the -t
option: frontail -t custom
On openhabian, frontail is started with a service.
You’ll have to edit the service definition and restart:
sudo nano /etc/systemd/system/frontail.service
- At the
ExecStart
line, look for-t openhab
and change it to
-t your_css_file_name_without_.css
(-t custom
for custom.css) - Exit using CRTL+X and save changes.
- It is necessary to reload the daemon:
sudo systemctl daemon-reload
- Restart frontail
sudo service frontail restart
An example theme to go with @gman his HABPanel RELOADED theme:
@import 'dark.css';
body {
background-color: #212124;
border-left: 5px solid #4F6949;
border-bottom: 1px solid #4F6949;
border-bottom-left-radius: 30px;
padding-bottom: 1em;
}
.navbar {
background-color: #4F6949;
}
.line {
color: #55a53a95 !important;
background-color: #212124 !important;
border-color: #55a53a60 !important;
font-size: 1.2em !important;
padding-left: 2em;
}
.line span {
color: #55a53a95 !important;
}
.line-selected {
background-color: #55a53a54 !important;
border-color: #55a53a60 !important;
font-size: 1.2em !important;
padding-left: 2em
}
.line-selected span {
color: #55a53a95 !important;
}
Note: The !important
keywords are necessary, because for certain log entries (i.e. ‘received command’) frontail dynamically adds a style
tag to elements.
It looks like this is configured specifically for Openhab, but I haven’t found where yet. If someone could elaborate, please do!
