[APP][Pro] SHRDZM Smartmeter - Real-time Energy Monitoring & GD28 Dashboard Display

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.

:rocket: 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.

:light_bulb: 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!
