Support for Logitech MX Master Mice

Andreas_Hegenberg · January 22, 2026, 9:24am

Unfortunately I can't seem to reproduce this, does this also happen with other actions? E.g. does a button 3 set to send shortcut "a" type a twice?

Andreas_Hegenberg · January 22, 2026, 9:30am

yes I got quite a collection during the last 2-3 weeks , most of them however just live in my backpack so I can work&test wherever I am

alexkirsz · January 22, 2026, 9:44am

Yes, it does.

alexkirsz · January 22, 2026, 9:45am

I can somewhat alleviate this by making it trigger on mouse up, as it seems there’s only one mouse up event triggering, but two mouse down.

Andreas_Hegenberg · January 22, 2026, 9:46am

Could you copy the debug logs and towards the end of the 10s logging window press the button 3 once?

Do you have this option enabled in your MX Vertical configuration?

alexkirsz · January 22, 2026, 9:56am

Yes. No change when disabling it.

Andreas_Hegenberg · January 22, 2026, 10:00am

It should stay enabled, that's fine. Your log doesn't show BTT trying to "configure" the mouse, which is kind of weird.

Are you sure logitech options / ghub / other mouse apps that could capture the mouse are uninstalled? Is your mouse connected via Bluetooth?

alexkirsz · January 22, 2026, 10:02am

Yeah that’s my bad, I had removed this configuration from the settings when last capturing logs. Here are logs with it:

The mouse is connected via USB and I have uninstalled all Logitech software using the command BTT recommended.

Andreas_Hegenberg · January 22, 2026, 10:03am

Ah interesting, is it a USB only mouse (then it would be a different model than mine) or are you using the optional cable?

The new logs shows various issues, I'll try to see whether I can figure out why they happen. Maybe connecting my mouse via USB will show something.

alexkirsz · January 22, 2026, 10:05am

I’m using the optional cable. I’ve just tested w/ Bluetooth and I can’t reproduce the issue.

Andreas_Hegenberg · January 22, 2026, 10:13am

Thank you, I think that lead me to root cause and the fix probably helps with other USB connected mice as well.

Can you check with BTT 6.099 once it finished uploading? (about 10 minutes)

seldo · January 22, 2026, 10:46am

When dumping the logs for my Logitech mouse, I saw that you get the mouse battery level.

Since I do not have the Logi tool anymore, and since it is on the dongle, not on Bluetooth, there’s no way for me to know when the battery is low, and I just know it when its empty.

Can BTT send a notification to tell me “Battery at <battery_threshold>% for <mouse_name>”?

Andreas_Hegenberg · January 22, 2026, 10:49am

You can get the battery level, here is an example:

You could put that into a repeating trigger that shows a notification once the battery level dropped below a certain level, or maybe show the battery level on every BTT launch or something similar

alexkirsz · January 22, 2026, 10:49am

That fixed the issue with Button 3, but now Button 4 is no longer detected at all

Andreas_Hegenberg · January 22, 2026, 10:51am

Did you re-enable the make all mouse buttons available option?

alexkirsz · January 22, 2026, 10:55am

Yes. Here are the latest logs.
