Just Installed BM-2 Battery Monitor and NOCO On Board Charger

Managed to get them both under the battery cover. Nothing visible.
Can receive BM-2 signal in the house from garage, just about.

Any tips on BM-2 from users?
Like, maybe, phone permissions? Or security? Is the app going to drain my phone battery, lol?

First thing I saw was this. Hey, it's a work in progress, lol:



The NOCO is for another, hopefully warmer, day.

 

The BM-2 is for information. The NOCO is an on board “trickle” charger, to be used when needed.

 

No

 

I saw a periodic parasitic draw last nighty while the car was parked in the garage.
It occurred every 2-3 hours.
The periodic draws stopped after midnight, which is a good thing.
Car was unlocked, thumb drive plugged in, ~33F in garage, fob inside house.
Toyota Connected 'waived', but not physically disabled.
Something seemed to run for a few minutes, which drew down the battery voltage thereafter-almost like a motor.
Is there some kind of pollution pump (fuel vapors?) that could be the culprit?

 

Well, I thought I'd see if my fob was in range from the kitchen counter out to the garage, so I hit the Panic Button. Yes, it did set it off, so as far as isolating the fob, I guess I didn't.
edit: Although, it's not near enough to do the near field stuff, like turn on the lights when the door is locked (just one example, I'm sure there are many, lol.)

 

Well dig this:
For laughs I tried the app on my MacBook Pro.
Seems to work perfectly!
Plus, I think the Bluetooth range may be greater.
edit: Same size display as phone.
Since it records 31 days of data when out of sync, may just as well use the MacBook and save any battery drain on the phone. Maybe there'd be a need for it on the road, coming home after a vacation and preemptively checking battery strength before turning on car.
edit3: Wait a sec...I pushed the green window arrows button and it expanded to the entire screen!
Perhaps I shouldn't have app on constantly for car battery drain purposes-unclear if 1.5mA drain is when it's synched. Seems to be updating charts constantly.

Can't resize, but still cool:

 

With the MacBook, I think I would get notifications for low battery on both the iPhone and the MacBook. I disabled the location setting permission on the MacBook. Hey, it's a work in progress. It is a very cool toy, though. And potentially quite useful.

 

No NOCO.

 

This morning at 7 AM it was 12.66 V.
The low reading I got initially was just when I first installed the device, so maybe throw out that observation.
You can see a degradation though with recent reading. I'm not sure if I'll ever get to the point of extrapolating out to days-until-dead, never mind actually observing it, since I like/need to drive every day. It'll also be interesting to see behavior in summer.

 

My GEN5 is charging at 14.4, maybe an occasional 14.3, per OBDC as well as the BM-2.
