“The DTSU666 is the same meter that I have installed as well. Do you have up‑to‑date firmware versions on your devices (dongle, inverter, etc.)? ---

Hello @Andi , excellent job and evolution you are doing here. Love the fact you added the SmartCharger for EVs. Question what options will be available in flow cards? Can a flow be, “when” export to grid starts “and” if SmartCharger have cable connected, “then” starts charging EV? Will there be such an interaction/capabilities? Can’t wait for my sytem to be installed. Thanks, Gonçalo ---

Awesome! The new Emma Modbus works great and acts like an inverter now! I could not get the new EMMA battery to work but the normal battery works anyway! ![1000003919](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/f/7fb17fe3ddf5e91e464a803a6d686c97f8975da0.png) ---

Salü Andi Happy to support testing! My setup: - SmartGuard-63A-T0 (EMMA integrated) - SUN2000-8KTL-M1 - LUNA2000-10KW-C1 Until now i managed my setup with Virtual devices for the energy tab and the app Solaredge + Growatt TCP Modbus. Disabled that all and started using your (starch vermissti) App. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/f/cf47cd7629c73499fe7a219337a8c8376bed0d16.png) so far so good → let’s see 🙂 Beschte Dank voruus! ---

Guten Abend Andi I’m missing the “THEN” cards for the EMMA devices - e.g. : - storage\_working\_mode\_settings (Battery) → Betriebsmodus Speicher - i can change them manually but not with a card - storage\_excess\_pv\_energy\_use\_in\_tou → PV Überschuss Nutzung - dito (no scenario for me currently) thx ---

The EMMA Modbus interface exposes only **read-only** registers for the Smart Charger — there are no write registers at all in this table. Starting, stopping, or controlling the charge power is therefore not possible through the EMMA Modbus driver. If anyone has the **other Modbus Interface Definition** (the full spec, not the EMMA subset) and knows whether charger control registers are documented there, or has experience controlling the charger via a different route, please share — happy to implement it if the registers are known. ---

I am on newer software versions (although I don’t know whether that matters): - **SDongleA‑05:** V200R022C10SPC312 - **SUN2000‑10KTL‑M1:** V100R001C00SPC173 - **LUNA2000:** V100R002C00SPC637 Attached is the explanation of how the values are derived: All registers of the **DTSU666 driver** (read from **SUN2000 registers 371xx, Unit ID 1** ): | Register | Name | Type | Unit | Capability | Note | | --- | --- | --- | --- | --- | --- | | 37101 | Grid Phase A Voltage | INT32 | V | measure\_voltage.phase1 | | | 37103 | Grid Phase B Voltage | INT32 | V | measure\_voltage.phase2 | | | 37105 | Grid Phase C Voltage | INT32 | V | measure\_voltage.phase3 | | | 37107 | Grid Phase A Current | INT32 | A | measure\_current.phase1 | | | 37109 | Grid Phase B Current | INT32 | A | measure\_current.phase2 | | | 37111 | Grid Phase C Current | INT32 | A | measure\_current.phase3 | | | 37113 | Power Meter Active Power | INT32 | W | measure\_power | inverted: + = consumption | | 37119 | Grid Exported Energy | INT32 | kWh | meter\_power.exported | | | 37121 | Grid Accumulated Energy | INT32 | kWh | meter\_power | total grid import | | 37132 | Grid Phase A Power | INT32 | W | measure\_power.phase1 | inverted | | 37134 | Grid Phase B Power | INT32 | W | measure\_power.phase2 | inverted | | 37136 | Grid Phase C Power | INT32 | W | measure\_power.phase3 | inverted | **Important:** All registers are in the **SUN2000 address space** — use the IP and Modbus ID of the **SUN2000** , not of the DTSU666. The signs of registers **37113 / 37132–37136** are inverted because the SUN2000 convention is **+ = export** , but Homey expects **+ = import**. The **371xx registers are SUN2000 registers, not DTSU666 registers**. The driver does **not** read the DTSU666 directly — it reads the meter data that the SUN2000 collects from the DTSU666 via RS485 and exposes in its own holding registers **37101–37136**. This means: - The IP address must be the **IP of the SUN2000 / SDongle** , not the DTSU666 - The Modbus ID must be the **Unit ID of the SUN2000** (default: 1), not the meter’s ID - The DTSU666 itself has **no LAN/TCP connection** — it is only connected via RS485 to the SUN2000 ---

This is correct as per this other discussion I found: [Huawei FusionCharge Wallbox · evcc-io/evcc · Discussion #10262 · GitHub](https://github.com/evcc-io/evcc/discussions/10262#discussioncomment-15945630) Only via OCCP protocol it is possible but there are some limitations below 4.2kW still needing development from Huawei R&D But I also found that it has the option to activate modbus on itself independently: [https://docs.eniris.be/en/Controller/Devices/EV-charging-station/HuaweiSCHarger](https://docs.eniris.be/en/Controller/Devices/EV-charging-station/HuaweiSCHarger) ---

Hi @Andi Shouldn’t the curve for Electricity total (value of measure\_power?) be \*-\*1? The curve is is blue for importing, but the battery is full and currently exporting. In my opinion the Netzwerkleistung should be \* - 1. ![86019](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/f/0ffb99f6930fcb9f8e6e937e642a27029af6ab79.jpeg) Energy SDK screenshot ![86020](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/6/8603d37e76495a820898847851cefe5482297f99.jpeg) ---
