Displaying mouvements even with OSD alg disabled / movement alarm

I'm wondering if it would be possible to display power and spectrum even with OSD alg disabled.

It allows to understand if my son move without going at his side.

For example, there are many days when I work while he is resting after seizure, often waiting for the next one.
Knowing that there are no movements is important to me because it would be dangerous for him to walk in that state. Knowing that he is sleeping in his bed is a way to keep my peace of mind.

Maybe we could do it another way and create a movement alarm. Just an ideaPierreSent from Android deviceLe 1 août 2026 11:50, Graham Jones ***@***.***> a écrit :jones139 created an issue (OpenSeizureDetector/Android_Pebble_SD#267) Discussed in #266 Originally posted by pmithrandir August 1, 2026 I'm wondering if it would be possible to display power and spectrum even with OSD alg disabled.

Since #278 unused tabs are no longer showing on the display, so maybe this could work as a quick fix:

• Leave all algorithms as they are now.
• Additionally enable the OSD algorithm

Set the threshold for the OSD algorithm to a value that correctly detects movements like e.g. walking.
Set the OSD Spectrum Ratio to a high value (like e.g. 999), so that OSD will never trigger an alarm. The movements however will still be visible on the OSD tab, based on the threshold setting.
ML, O2 or heart rate will continue to trigger alarms as before.

The disadvantage: it is not possible to display e.g. the heart rate monitor and other tabs together with the OSD tab.
But maybe this helps until someone has a better solution?

that's already quite a good workaround
and I can check other values in the other algo panel
