Elgato's eve Energy Wireless Power Sensor & Switch looks similar to the Koogeek switch reviewed next. Yet, it has several design advantages over its competitor. First, there's a switch on the front of the plug that glows green when the outlet is on and also acts as a hardware reset button. Second, the AC power plug is offset to the upper third on the back of the device. This allows you to plug it into a duplex socket and not cover the second outlet.
If this is the first HomeKit device you're installing, just tap "add accessory" on the eve Energy app and follow the instructions that appear on the screen of your iOS device. Like all three SmartPlugs reviewed here, you'll need to either enter the eight-digit code manually or use the camera on you iOS device to scan the number which appears on the back of the eve Energy quick start guide. If this isn't your first HomeKit device, just tap the setup icon at the bottom of the eve Energy app and then tap the "+" key to initiate a search for your new Switch & Power meter.
When you first launch the eve Energy application, you land at the Rooms page. Listed on the left are the zones (first floor, second floor) and the rooms that belong in each zone. On the right side of the screen, you'll see details for each of the devices, or accessories as they are called in the HomeKit world. In the rooms, the accessories appear with their Siri names to make it easy for you to control them using Siri from here. The eve Energy Smart Outlet has the Siri name "Fan" along with a corresponding fan icon chosen from an icon library.
You can configure the data that appears on this screen by clicking on the Edit icon located in the upper- right corner of the screen. For the purposes of the screenshot, I'm displaying all available data for the eve Energy "Fan". The iHome Switch also resides in the Office, but it is a switch without power monitoring capabilities. The only option other than power, was "in use", which scrolled off the screen.
Elgato Eve Energy Rooms
There's a lot going on in the image below. To create this image, I clicked on the edit button in the upper left corner, and I toggled the expand directory ">" that appears next to the Project Cost, Total Consumption, and Total Cost menu items. Here's what's going on. On the left side of the screen, you can see the rooms (top) and how many accessories are in each room. At the bottom of the screen, you can see the configured zones and the number of rooms in each zone. You can change the orders of the Rooms or Zones, and you can change the which rooms belong to each zone from this menu. To change which accessory is assigned to each room, you need to go to Settings>Accessories>Room and reassign it. This is also where you can edit the Siri name for each accessory.

Looking at the right side of the screen, you see the projected cost is estimated on day usage. You can also project the annual cost based on a minutes average or a weekly average. Total consumption shows that about 2.5 KWh have flowed through the switch since I started testing it. The bar graphs can be dragged to the right showing the previous history. Similarly, the Total Cost is based on the total KWh used multiplied by the rate energy that I set - $0.181/KWh.
There's even more detailed information available than is shown on the graphs. If you double tap the date bar under either the Total Consumption or the Total Cost graphs, additional more detailed information will appear. You can view bar charts with views for an hour day, week or month. Under the expanded view for Total consumption, there's a measurements menu. You can drill down into detailed daily power consumption that's recorded in approximately 10-minute increments. In my tests, I was able to export a single day's consumption records or Total Monthly consumption in .csv format via email.
The short gallery below shows the detailed information that is available.
Switching to other rooms, I checked energy consumption detail was available for other manufacturer's devices using the eve Energy app. The ConnectSense Smart Outlet, configured for the living room, showed the most detail. The screenshot below shows that the eve Energy app had access to the current energy data, but not any usage information beyond the state data. Rather than showing power (Watts), the data reported was in amps.
Outlet one was 0.4 A and outlet was 0.3 A. The state times shows that both outlets had been energized (State timer) for 2044 seconds. The 0.4 A corresponds to the 48 W reported for Outlet one and the 0.3 A corresponds to the 36 W reported by Outlet Two in the ConnectSense app. The Koogeek Outlet (Bedroom) reported 18 W matching what was shown in the Koogeek app. No additional data was available to the eve Energy app.

Like the ConnectSense app, the eve Energy app has a navigation bar across the bottom of each screen. I'll discuss each one briefly.
At a Glance
The left most menu, At a Glance, addresses one of my complaints about the ConnectSense app. At a Glance, shown below, shows a summary of all devices by room. Optionally, you can tap the "All" link at the top right of the page to select individual zones. This could be useful if you had a very large HomeKit device installation.

The Scenes menu combines the functions found in the ConnectSense Scene and Rules menus. To execute a scene, merely tap on the icon. It shows all scenes that have been created by any HomeKit device on the current iOS device. You can also create a scene and choose any combination of accessories and actions to include. One important thing to note: The eve Energy app is able to delete scenes, timers and rules created by itself, or any other application. This was a very handy feature, as I was able to clean up test rules, events, and timers from other applications.
The Timers function is exactly like what I found in the ConnectSense app You create a timed event and select once or repeating. If you select repeating, you have the same options of minute, hour day or week. Once you select the trigger time for the event, you choose the scene name(s) you want to execute. Like the ConnectSense timer rules, you can't choose the days of the week, nor can you create a timer based on sunrise/sunset.

The Rules feature is exactly like the ConnectSense Rules-based event. You configure a rule the same way: Select one or more triggers, select conditions that must be met (ConnectSense calls them constraints) and then select the scene(s) that you want to execute if all of the triggers and conditions are met. It takes a few tries and a little experimentation to get the hang of these conditional rules, but ones you conquer it, you can create some pretty powerful automation.

The Types menu lets you view accessories by attributes that they have in common. In the screenshot below, the only attribute that all devices had in common was Power on/off. Only the eve Energy had the attributes related to power consumption, and only the ConnectSense had the brightness function which allows you to dim its indicator LEDs
This menu is arranged by room name in an order that you can select. The accessory names shown in this view are the Siri names. Each device can be turned on/off from this view.

The settings menu allows you to configure settings not found in other menus. Here you can configure individual accessories, change their name, Siri name, room assignment icon assignment and find out information about the accessory. Guest Access lets you invite other users to control your HomeKit environment. You can also create groups of multiple accessories that you want to treat as a single accessory. The settings menu is where you set the Energy cost per KWh that is used to calculate total energy costs. The screenshot below shows the Accessories menu selected.
