[Ovmsdev] High hologram usage

[Craig Leres]

I have three ovms modules, two are in cars and one is on the bench. Most 
of the time they are on my home wifi.

hologram used to bill me less often than once a month. But I noticed 
recently this had increased to about once every three days. When I 
looked at usage (see attached) things changed in early January.

I keep an archive of the builds I've run. On January 8th I upgraded from 
3.3.004-246-ge9decc46 (September 8th, 2024) to 3.3.004-332-gadce9471. 
That seems to be when hologram usage increased.

Last week I upgraded to 3.3.004-382-ge83be0e7 but usage still seems 
high. I looked a per-sim usage and though I put similar miles on each 
car in a month, one is 50% higher than the other. But even the dev unit 
is way higher than I would expect for a module that is *always* in range 
of wifi.

What am I missing?
