Summary
VictronConnect exports device settings as .vcsf files. Format verified on VictronConnect v6.x exports (SmartSolar MPPT and SmartShunt); older app versions not tested. On-disk layout:
offset 0..4 magic "VCCFH"
offset 5..8 4-byte header (preserve on re-encode; meaning not fully documented here)
offset 9.. zlib-compressed UTF-8 JSON
Minimal decode:
import json, zlib
raw = open("export.vcsf", "rb").read()
assert raw[:5] == b"VCCFH"
doc = json.loads(zlib.decompress(raw[9:]))
# doc["appversion"], doc["data"]["/Settings/..."], etc.JSON round-trip decode/re-encode is lossless in local tests when the 4-byte header is copied from the source file. Importing a re-encoded .vcsf back onto a device via VictronConnect is still unverified.
Why this might help here
This repo already reverse-engineers VictronConnect / BLE. .vcsf is the app's settings backup format (not Instant Readout), so this is optional context for anyone decoding exports or comparing charge profiles offline.
