Short or garbled gateway responses are rejected on register count
instead of half-decoding (previously: 'unpack requires a buffer',
OverflowError on garbage scale factors). Scale factors outside
+/-10 and non-finite floats are dropped before they reach line
protocol.
offgrid is written as integer offgrid_state: the existing DB
cannot be migrated (mixed inmem/tsi1 shards block all deletes)
and the old boolean field conflicts with integer writes, which
poisoned the spool - HTTP 400 now drops the batch and logs the
InfluxDB error body instead of re-spooling it forever.
grafana_dashboard.json: fully German dashboard (InfluxQL,
InfluxDB 1.x) with off-grid state, SoC (SoE*SoH/100) and
consumption-source panels; status tiles use integers plus value
mappings because Grafana drops string/boolean fields from
InfluxQL time series.
Polls now cover meter 1, battery 1 and storage control blocks,
plus inverter event registers for off-grid detection (vendor
event bit 0). Register layout validated by probing a
SE10K-RWB48BFN4 with fw 0004.0025.0011; battery and storage
floats are word-swapped on this device.
Failed Influx writes spool to disk and replay on the next
success (Influx reached over WAN). Modbus blocks that fail to
read are skipped for that cycle; the flaky gateway must not
kill the daemon. Battery lifetime counters at 0xE176/0xE17A
hang the device and are never read.
BREAKING CHANGE: config.yaml 'mqtt:' section replaced by
'influx:', Home Assistant discovery removed.
