Home Assistant Energy Monitor Dashboard
Budget: $10 – $30 USD
Request for Proposal (RFP): Home Assistant Energy Monitoring Dashboard
RFP Number: HA-MFM376-001
Date: October 26, 2023
Issuing Organization: Infinitumtech
1. Project Overview
We require the design, integration, and configuration of a real-time energy monitoring dashboard within Home Assistant. The system will use data from a Selec MFM376-C-CE multifunction power meter, communicated via a Waveshare RS485-to-Ethernet converter.
2. Scope of Work
The selected vendor must deliver a fully functional system as outlined below.
2.1 Hardware Integration & Configuration
• Verify and configure the Modbus RTU communication parameters (baud rate, parity, slave ID) on the Selec MFM376 meter.
• Configure the Waveshare Serial Server with a static IP address and set it for transparent Modbus RTU-to-TCP bridge mode.
• Advise on proper RS485 wiring termination and physical installation if required.
2.2 Home Assistant Core Integration
• Configure the native Home Assistant Modbus TCP integration to connect to the Waveshare server.
• Create and define sensor entities for all key parameters by correctly mapping the Selec MFM376 Modbus register map (to be provided). Essential parameters include:
o Phase Voltages (V1, V2, V3)
o Phase Currents (I1, I2, I3)
o Active, Reactive, and Apparent Power (total and per phase)
o Power Factor (total and per phase)
o Grid Frequency (Hz)
o Import/Export Active Energy (kWh) – from multiple tariff registers if available.
2.3 Dashboard Development
• Design and implement a Lovelace dashboard with a clear, user-friendly layout.
• Include visualizations such as:
o A summary gauge or card for current total power (kW).
o Historical line graphs for power and energy consumption.
o Numerical readouts for key electrical parameters in a clean card-based layout.
o Visualization of three-phase voltage and current balance.
2.4 Optional/Advanced Features
• Implementation of energy cost tracking using utility rates (fixed or time-of-use).
• Creation of automations or alerts for high-power thresholds or phase imbalance.
• Configuration of long-term data storage (e.g., using InfluxDB) and advanced Grafana dashboards.
• Setup of energy management features using the Home Assistant Energy dashboard.
3. Deliverables
• A fully operational Home Assistant integration with all sensors reporting correctly.
• A completed and functional Lovelace dashboard as per the requirements.
• Documentation including the sensor configuration (configuration.yaml snippets), dashboard configuration, and a system operation guide.
4. Vendor Requirements & Proposal Submission
• Experience: Demonstrable experience with Home Assistant custom integration, YAML configuration, and the Modbus protocol.
• References: Examples of previous similar projects (e.g., energy monitoring dashboards).
• Proposal Format: Please structure your quote as follows:
o Total Fixed Price
o Estimated Timeline for project completion.
o Description of project management and communication approach.
5. Attachments for Vendor Reference
• Product Link: Selec MFM376 Meter
• Product Link: Waveshare RS485-to-Ethernet Server
Comprehensive Documentation & Video Guide
o Step-by-Step Technical Guide: Requires a detailed manual covering the full system setup, troubleshooting, and future modification.
The video must chronologically cover:
o Hardware Setup: Physical wiring of the meter, RS485 cable connection, and Ethernet server installation.
o Device Configuration: Step-by-step configuration of the Selec meter's Modbus settings and the Waveshare server's network parameters.
o Software Integration: Full process of adding and configuring the Modbus integration in Home Assistant, including sensor entity creation.
o Dashboard Build: Real-time creation of the Lovelace dashboard from a blank state to the final layout.
o System Verification: Demonstrating that live data flows correctly and explaining how to troubleshoot common issues.
