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.

## Invariants locaux
|
|
1. NE PAS renommer les paquets PUBLIÉS : `powersync-plugin-eastron`,
|
|
`powersync-plugin-abbb2x`, `nymea-plugin-abbterra`. Casse l'upgrade des box beta.
|
|
2. `abbterra` est volontairement sous nom amont (transition upstream propre) — ne pas « corriger ».
|
|
3. Matrice validée beta : SDM72 / SDM120 (eastron), Waveshare D8.
|
|
4. Aucun composant propriétaire ici.
