Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

ioBroker Sigenergy Adapter

NPM version License: MIT

Adapter for Sigenergy solar energy systems via Modbus TCP/RTU

Supports the Sigenergy Modbus Protocol V2.5 (released 2025-02-19).

Features

  • 📡 Modbus TCP (Ethernet / WLAN / Optical fiber / 4G) — Port 502
  • 🔗 Modbus RTU (RS485 Serial)
  • ⚡ Full register support — All plant and inverter registers per V2.5 spec
  • 🔋 Battery statistics — Time to full, time remaining, daily coverage
  • ☀️ PV statistics — Self-consumption rate, autarky rate
  • 🔌 AC Charger (Sigen EVAC) — Optional
  • ⚡ DC Charger — Optional
  • 📊 Calculated values — Derived statistics updated each poll cycle
  • 🖥️ VIS Widgets — Energy flow, battery status, statistics panels

Supported Hardware

| Category | Models | |-----------------|--------| | Hybrid Inv. | SigenStor EC SP/TP, Sigen Hybrid SP/TP/TPLV, Sigen PV M1-HYA, PG Controller | | PV Inv. | Sigen PV Max SP/TP, Sigen PV M1 | | EVAC (AC) | Sigen EVAC 7/11/22 kW, PG EVAC |

Default Modbus Addresses

| Device | Address | |--------|---------| | Plant (read/write) | 247 | | Plant broadcast (write, no reply) | 0 | | Inverter | 1 | | AC Charger (EVAC) | 2 |

Configuration

Connection Tab

  • Connection Type: TCP (Ethernet) or Serial (RS485)
  • TCP Host: IP address of your inverter

VIS Widgets

Note: All 7 widgets are provided by the separate ioBroker.vis-2-widgets-sigenergy adapter. Install it alongside this adapter to use the widgets in VIS-2.

Energy Flow Widget

Shows animated energy flow between PV → Battery ↔ Grid → House.

Battery Status Widget

Displays SOC bar, SOH badge, time to full/empty, current power.

Power Overview Widget

Live reading of all four power flows.

Statistics Widget

Today's autarky, self-consumption, SOC min/max, battery coverage time.

Inverter Widget

Live inverter data: PV power, grid frequency, phase voltages, temperature.

AC Charger Widget (EVAC)

Status and power readings for the Sigen EVAC charging station.

DC Charger Widget

Status and power readings for the DC charger.

Communication Protocol
