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 🙏

Homebridge 3em Energy Meter

Homebridge 3em Energy Meter is a plugin for Homebridge that implements Shelly 3EM energy metering functionality in Homekit.

This plugin uses http requests to a Shelly 3EM (or EM*) device, making it possible to retain the native Shelly cloud statistics (which use MQTT) and at the same time allow you to monitor your energy consumption via Homekit.

Please note that due to the fact that Apple does not support energy characteristics in Homekit, this plugin's accessory will only show values in the third-party homekit application "EVE".

[Status]

It will show in the EVE application the following values: Voltage (the average voltage of all 3 phases), Current (the accumulated Ampere of all 3 phases), Consumption (the accumulated Watts of all 3 phases) and the Total Consumption (the accumulated kWh of all 3 phases as calculated by Shelly API. Note in order to reset this value you must reset it in the Shelly app). A Total Cost and Projected Cost will show if you have specified the Energy Cost in the settings section of your EVE application. Total Consumption and Total Cost will feature the fakegato-history graph.

This application uses the cool fakegato plugin (simont77/fakegato-history).

Please also note that the sole purpose of this plugin is the energy metering feature of the Shelly 3em in order to monitor your 3 phase installation. The Shelly 3em features also an actuator (switch) which is not implemented in this plugin. If you need to use the switch in Homekit please use other plugins, like for example the very good homebridge-shelly (alexryd/homebridge-shelly) plugin.

Installation Instructions

You can easily install this plugin by using the superb Homebridge Config UI X. Search for "homebridge-3em-energy-meter" in the "Plugins" tab and install the plugin. After that fill out the configuration by using the "SETTINGS" link below the installed plugin.

Alternatively, can you install the plugin by

         npm install -g homebridge-3em-energy-meter

and then edit your Homebridge's config.json to include the following in the accessories section:

    {
        "accessory": "3EMEnergyMeterAdv",
        "name": "Energy Meter",
        "ip": "192.168.0.1",
        "auth": {
            "user": "",
            "pass": ""
        },
        "timeout": 5000,
        "update_interval": 10000,
        "negative_handling_mode": 0,
        "use_pf": false,
        "debug_log": false,
        "serial": "123456789012345"             
    },
  • "name" The Homekit Accessory Name.
  • "ip" The IP address of your Shelly 3EM.
  • "user" and "pass" If your Shelly 3EM local web page is password protected specify "user" and "pass".
  • "timeout" The http/get request timeout in msec. This timeout must the less than the "update_interval", default is 5000.
  • "update_interval" The interval for pulling values in msec. Must be greater than "timeout" setting, default is 10000.
  • "use_pf" Enables the Power Factor (pf) usage when calculating Total Ampere.
  • "negative_handling_mode" Defines what happens with negative values. Set to 0 to zero them or 1 to show them as absolute values.
  • "debug_log" Enables the debug logging of the plugin, default is false.
  • "serial" This sets the published serialNumber of the accessory. It is required to use an unique serial for fakegato-history to work correctly.

Shelly EM functionality is beta, please use at own risk as I could not test it on a real EM device. The creator of this plugin is not affiliated in any way with Shelly(Allterco) or EVE.
