Index Sleep - No body battery

devilkin 4 days ago

I recently got an Index Sleep Monitor, and while it records a lot of things, body battery is not one of them.
As soon as I remove my Venu 2 Plus, body battery stops being reported, and it only shows up again once I put it on. I had not switched off my watch, just left it.

As you can see the body battery is being picked up again after I put on my watch.

All my devices report being completely up-to-date.

My watch is a Venu 2 Plus - is one overriding the other somehow?

The workaround as I found in some other posts doesn't work.

Last night I actually powered off my Venu 2 and put on my ISM.

In garmin connect app I saw it switch to the index sleep. Heartrate etc , but no body battery. Got up this morning, let it sync, and then powered on my watch. Still no BB.

Same issue here. No BB this morning, which is odd since the BB had been populating regularly up until last night. Also of interest is the skin temp did not record either.

Not sure if this is relevant or not but I took my ISM off at 5am and went for a workout. I noticed when I came back from my workout the ISM was still connected to GC. The ISM did not disconnect from GC until 832am. A full 3hr32mins after I took the ISM off.

This makes me wonder if the BB was not updated because the ISM did not know the ISM had been taken off and was still doing whatever calculations it does. Even though the ISM had been taken off at 5am and sync'd with GC.

Note, I do not leave GC connected to the ISM when sleeping. My phone is turned off and the ISM sync's only in the am when I take the ISM off and turn on my phone.
