Aucun registre de phases n'existe dans la carte Modbus V2C : la borne ne sait
pas dire si elle est câblée en mono ou en tri. La ThingClass ne le déclarait pas
non plus, et le repli du moteur pour un état absent est SILENCIEUX —
EvCharger::phaseCount() rend 1.
Sur une Trydan triphasée, cela publie un plancher de 1 380 W au lieu de 4 140
(6 A × 230 V × 1 au lieu de × 3) et convertit l'enveloppe allouée en un courant
trois fois trop élevé. La borne démarre, au mauvais courant, sans qu'aucun
journal ne le dise.
C'est la famille de défaut que le moteur vient de fermer en 3g-2 — un plancher
annoncé qui n'est pas celui qui gouverne le démarrage — rouverte côté plugin.
Trouvée la veille de la pose, en lisant la déclaration de classe plutôt qu'en
l'exécutant.
La valeur vient donc d'un RÉGLAGE (1 ou 3, défaut 1), recopié dans l'état que le
moteur lit, et réappliqué sur settingChanged pour qu'une borne recâblée se
corrige sans recréer le Thing. Le défaut 1 est celui du repli du moteur : une
installation qui ne renseigne rien se comporte exactement comme avant.
L'état porte minValue 1 / maxValue 3 — l'interface nymea evcharger définit
phaseCount avec ces bornes, et le validateur refuse la classe sans elles. S'y
conformer, c'est être lu par le moteur À TRAVERS l'interface, pas par une
convention propre au plugin.
Compile amd64 0 erreur / 0 warning.

- Decode SlaveError (reg 0x0BC5) with full table (codes 0-10) into new
slaveErrorMessage state; code 04 (WiFi reconnect) also surfaces in
statusMessage for immediate SAV visibility.
- Add L1/L2/L3 phase powers (regs 0x0BD9-0x0BDB, confirmed hw) as
diagnostic states polled every 30 s.
- Add RegChargeTime (0x0BC6) to enum for completeness (not yet exposed).
- Collapse debian/changelog to single 1.15.0+etm1 entry (new plugin).

The Trydan ESP32 WiFi stack saturates under nymea's periodic ICMP pings
(observed: latency > 14 s, Modbus timeouts, charger drops off).
Changes:
- NetworkDeviceMonitor removed entirely from setupThing() and thingRemoved().
The charger is expected to have a DHCP-reserved IP (documented in code).
Address comes from trydanThingAddressParamTypeId param — already the correct
path after the previous setup fix.
- Connectivity now derives from Modbus poll success/failure only (reachable()
from TrydanModbusTcpMaster), NOT from network ping. A ping response does
not imply Modbus usability on this hardware.
- postSetupThing() timer (30 s): if not reachable, calls connectDevice() for
reconnect; if reachable, calls update(). The 30 s period IS the backoff —
no aggressive retry loop.
- Modbus timeout: 2 s → 5 s (tolerates residual WiFi latency spikes).
- Modbus retries per read: 1 → 0 (abort fast on first timeout; full poll
sequence already aborts at first error via doNextRead).
- k_errorLimit: 5 → 3 (3 × 5 s = 15 s before marking unreachable).
- New state "statusMessage" (QString): set on disconnect with timestamp +
cause ("timeout Modbus — vérifier signal WiFi de la borne"); cleared on
successful poll. Visible in nymea-app; helps SAV without SSH access.
- "networkdevice" removed from JSON interfaces (contract broken without monitor).
Invariants preserved: Big/Big float32 decode, no block read, PauseState+Lock
mirror, PauseDynamic conflict management, writeCompleted address filtering.

Étape 1 complete: V2C Trydan nymea plugin (Modbus TCP, status Partial).
Plugin (IntegrationPluginV2c):
- discoverThings: delegates to V2cTcpDiscovery, maps results to
ThingDescriptors; createMethod "user" bypasses discovery.
- setupThing: registers a NetworkDeviceMonitor (IP tracking on DHCP
renewal), creates TrydanModbusTcpMaster, wires reachableChanged →
initialize() → state update on initializationFinished(), then starts
periodic polls on a 30s PluginTimer.
- updateThingStates: ChargeState 0/1/2 → pluggedIn/charging;
power = (PauseState==0 AND Lock==0) per evcc trydan.go Enabled().
- handleDynamicConflict: if Dynamic==1 (V2C internal PV optimizer),
write PauseDynamic=1 to suppress it. NEVER write Dynamic=0 (silences
ChargePower telemetry). Writes only on state transition to minimize
flash wear. cf. github.com/evcc-io/evcc/issues/28047.
- Action "power": writes PauseState then Lock (always in mirror), then
fire-and-forgets PauseDynamic if Dynamic==1. Action handlers filter
writeCompleted by register address to avoid reacting to concurrent
background writes.
- Action "maxChargingCurrent": clamps to [minIntensity, maxIntensity],
writes Intensity. Below 6A → pause instead of invalid setpoint.
JSON (integrationpluginv2c.json):
- ThingClass "trydan" implementing evcharger + connectable + networkdevice.
- settingsTypes: suspendInternalOptimizer (bool, default true) — allows
the user to disable Dynamic conflict management if they want the V2C
PID to remain active alongside the HEMS.
- State "chargeEnergy" exposed as diagnostic only (NOT sessionEnergy) —
firmware reliability on this register is unvalidated; cf. evcc #28047.
Build (v2c.pro):
- MODBUS_CONNECTIONS intentionally empty: the modbus-tool code generator
assumes non-overlapping block reads; leaving it empty skips generation
while still linking nymea-modbus via the PKGCONFIG in modbus.pri.
VendorId 56c3e7bb… is new (no existing V2C vendor in the repo).
PluginId f0692725… is new (generated for this plugin).
PORTING_STATUS_modbus.md documents register sources, the 4 items that
require validation on real hardware, and the "no beta matrix" constraint.
