I cannot see how the modem in your bench module "dev" could cause >8 MB network traffic when the module has Wifi all the time, except by many reconnects + Hologram counting these as traffic (which I think they shouldn't and don't do), or by the module not using Wifi due to a test or very poor signal level.
The only modem change coming to my mind is the GSM signal quality extension by Jaime, which initially had switched good & bad signal levels. But that wouldn't have triggered a modem reconnect, rather reboots, and that wouldn't have gone unnoticed by you.
You can check the cellular reconnect count from "cellular status debug". Of course that only counts reconnects that need an IP renegotiation, not transparent transitions to other cell towers.
Looking forward to your findings.
The version that causes problems for me is 3.3.004-324-g367f6b95
That would be commit 367f6b950f62adef04c8c877f5e29889e6e22c64, which only included minor changes to the e-Up module, so that can be ruled out as the causing commit.
https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/ commit/367f6b950f62adef04c8c877f5e29889e6e22c64
My testing found: 3.3.004-323-gbc1f75c9 24Nov24 good 3.3.004-324-g367f6b95 25Nov24 BAD When I run: git diff bc1f75c9 367f6b95 I see a *lot* more changes than in the url you show above. I guess there are somehow multiple commits hidden in the range between 323 and 324?
All modules are using a lot more cellular data but one in particular stands out. It's the one with the lowest wifi dBm but it's not *that* bad, but it makes me wonder if there is some kind of wifi power saving that's making wifi frequently unavailable causing cellular data usage (combined with something in this version that is 10X as chatty -- I suspect fixing this will get my usage back down).
Did you check your network wifi SQ & reconnect settings?
I don't know what those are (and it seems to be somewhat of a POLA violation that the default config would use 10X the cellular data (especially for modules that are on wifi).
Not that they would make any difference from that commit, but maybe it's not the commit but some random Wifi fluctuation causing an occasional switch to cellular.
That should be clearly visible in the logs though.
I guess I have more commit hashes to test. Craig
