SwiftBar VS bitbar

I don't know if this supports your use case, but look into SwiftBar. https://github.com/swiftbar/SwiftBar

I’m in a similar boat. Only one external monitor on an M1 Studio. Every time I restart, GeekTool cannot find the monitor, so I have to manually move all 10 of my geeklets to the main monitor. I looked into moving them via script, but was unsuccessful because the monitor id was inexplicably not identical on geektool’s side between launches (I gather this is a known issue from the developer). Sadly, I have been unable to find an app that sufficiently replicates GeekTools functionality. That being said, I have moved some of my scripts to SwiftBar where they are accessible via the menu bar instead of displayed on the desktop. Works fine for simple text stuff, but not my more graphical calendar. I’m saving this post though, because I still want a true fix/replacement for GeekTool.

As many of you, I obsess over the current metrics of my TMHI modem. Opening the app to check it is too cumbersome. On MacOS there is a cool free utility that allows simple scripts to run in the menu called SwiftBar (get it here: https://github.com/swiftbar/SwiftBar )

Maybe swiftbar?

I am sure you could create a stock ticker with SwiftBar https://swiftbar.app. SwiftBar has plugins which write to the menubar using shell scripts. And there are already some stock ticker plugins - I am sure you could modify one of them to meet your needs.

While no broken out per plug, APC UPS network management cards provide total power output data (current, voltage, frequency, power) via SNMP, which you can log using a wide variety of tools.

And even without external tools, historical power usage logs are available via the APC Web UI.

While I don't currently log anything externally, I use an xbar[1] script[2] to display UPS output current in my Mac menu bar.

5. Download and install xbar https://github.com/matryer/xbar

Maybe with https://xbarapp.com/ ?

Maybe with xhttps://xbarapp.com/bar? You can also take a look here.

Maybe you can use AnyBar https://github.com/tonsky/AnyBar/ or xbar https://xbarapp.com/

xbar (Free) xbar is free and open source it allows you to put anything in your macOS menu bar, although the learning cure is high, I would put this in development too..
