Hi everyone,

I am excited to introduce the **SHRDZM Smartmeter** app! This is an all-in-one solution for everyone using SHRDZM hardware to monitor their energy flow and visualize it in real-time.

**What does it do?** The app integrates the SHRDZM Smart Meter Bridge and the GD28 Dashboard into Homey Pro. It’s designed for speed and flexibility.

**🚀 Key Features:**

- **Hybrid Data Protocol:** Supports **Modbus TCP** (stability) and **WebSocket** (ultra-fast real-time updates) – even in parallel!

- **Full Grid Overview:** Monitor active power (W), cumulative energy (Import/Export), voltage, and current for all three phases (L1, L2, L3).

- **GD28 Dashboard Control:** Take full control of your GD28 E-Ink display. Use Flows to push data like PV yield, grid consumption, or any other Homey tag to your screen.

- **Flexible Layouts:** Supports Fullscreen, Bar Charts, Gauges, and a 4-value Matrix view.

**💡 Pro Tip (The Carousel):** You can easily create a “Sliding Dashboard” by using a timer flow that cycles through different views (e.g., showing your consumption for 5 seconds, then switching to PV yield).

**Hardware required:**

- SHRDZM Smart Meter Bridge (e.g., for Sagemcom T210-D) or

- SHRDZM GD28 Dashboard Display

I’m looking forward to your feedback and cool Flow ideas!

And here’s the flow for it:
