Wi-Fi outlets are at about 1.5-2 Watts of power consumption, that's the WeMo as mentioned in Jim's answer, and also a few other ones I've tried, like the TP HS110. ZigBee outlets like the one from Samsung SmartThings should use less power due to the ZigBee protocol usage. According to their support forums, it's about 0.3W when the relay is off and 0.6W when ...

To understand better the power consumption of smart plugs it's worth peeking into them. To do so let's see some smart plug reference designs. One from Atmel One from Texas Instruments As you can see the parts of these two different designs are quite the same. There is an AC/DC power supply which provides the DC voltage for the sub-circuits. There is a "...

There are plenty of smart plugs, based on ESP8266 chips, which can be flashed with new firmware relatively easily. A popular (open source) firmware that has a lot of users and community support is Tasmota. This firmware is easily integrated to a locally hosted home-automation ecosystem which can be accessed remotely via the internet. The device also will ...

A WeMo Rep stated 1.5 Watts for their wall switch on a WeMo forum. I imagine most of these wall/socket switches will draw 1-2 watts in standby. WeMo Community Thread

A couple of options off the top of my head. Sonoff kit, can be flashed with open source firmware that allows control via MQTT/HTTP. While not sockets directly adding it into the cable is not hard. The Sonoff Pow does control and power monitoring. Belkin's WeMo sockets use SOAP messages and uPnP which is self describing (you can see my notes on working out ...

Electrical expert on diy.se with a public service announcement / context challenge. Don't buy anything that touches mains power on Amazon Amazon is a river of cheap Chinese junk. Amazon lets anyone (i.e. The Ebay/Alibaba crowd) sell on their platform. This is called the Amazon Marketplace, and consists of any listing that says "Ships from and sold by ...

This video from 2015 shows an Aeotec Z-Wave Smart Dimmer measured at: ~0.4W idle ~0.6W on but fully-dimmed (no load) I assume these switches have a similar power usage as an outlet/socket, given their similar functionality. Outlets could be slightly lower, given no need for dimming circuitry. The person writing this post from 2016 purports to work for "a ...

Google Home seems to figure out the "type" of an outlet via the name. If the name includes the word "lamp" or "light", then it's considered a light and will become part of the light set, and participate in the "turn on/off the lights" commands. So, change the name of the device to something that includes "lamp", wait a while, and eventually it will be ...

Yes, "smart sockets" seem to be readily available on the market. Some examples include: UK: Lightwave. Particularly the LW260 1 gang socket, LW270 2 gang socket and the L42 2 gang socket seem to be what you were looking for—a smart plug socket without any bulky extrusions. With regard to legality, Lightwave say, "All Lightwave devices are safe and legal to ...

You have already capability to publish data over MQTT protocol, even a broker and way to forward certain requests to Spring from the socket. I see no point of taking the responsibility of knowing whether socket is plugged for some requests for Spring. MQTT broker does that under the hood, you don't have to invent the wheel again. So, I would create some ...

Most smart plugs I have come across are Wi-Fi controlled devices. I expect the regulations would be similar to those imposed on a Wi-Fi router such as Technicolor's TG582n. RTTE Directive 1999/5/EC: Radio and Telecommunications Terminal Equipment. Commission Regulation (EC) No 1275/2008 implementing Directive 2009/105/EC: Ecodesign requirements ...

According to this TPLink page the HS-100 units are rated at 13A maximum. You can switch a load of essentially any size by using the HS-100 to switch a secondary relay (solid state or electromechanical.) Electromechanical relays able to switch many kilowatts are available at prices that are usually well below the cost of the automation system switches. You ...

Your AC is rated at 4.9A, and the switch appears to be rated at 10A, so you've done nothing 'obviously' wrong (unless the device is marked explicitly not suitable for switching motors or inductive loads). However, to me the 10A current rating doesn't seem very believable. I'm not sure I'd want to trust that plug for even 5A. The big problem is that your AC ...

I measured a number of devices with an ELV Energy Master, which is known to be quite accurate. These are the results: Device off on both on TP-Link HS110 V2 1,2 W 1,8 W x TP-Link HS110 V3 1,0 W 1,8 W x AVM FritzDect 200 0,5 W 1,3 W x Gosund SP111 0,3 W 0,6 W x Blitzwolf SHP7 0,3 W 0,7 W 1,1 W ...

I'm not aware of any generic local discovery capability built in to a browser. In fact I would consider any capability to be a security venerability as it would allow attackers to profile the your network remotely unless it had a manual interaction step to start it, which would really slow down the workflow I think you are aiming for. I can think of 2 ...

Update: This device did not meet the requirement of scheduling a gradual dimming. It only turns on or off fully. I bought the Leviton DW3HL-1BW.

Are you willing to at least connect the device to the internet for initial configuration (which will include the near-mandatory 'apply updates' phase)? Here's what should work - Set up two wifi networks within your home. Most people have an old wifi device that they've superseded. Your primary home wifi / router device will be the internet gateway, with ...

There is also a company called "Allterco Robotics". They introduced the "Shelly". This is a very small piece of ESP8266 Hardware and some open source software. You can place them behind your existing plugs and control your plugs via WiFi afterwards. https://shelly.cloud/shelly1-open-source/

The Sonoff line is very diy-friendly, breaking out the ESP8266 headers you need to program it. Anything Wi-Fi under $10USD/ea commercially will probably be using an ESP8266. They probably won't get a lot cheaper than that, there's just no margin down there. In the DIY market, there's nothing else Wi-Fi and programmable under $5/ea and commonly available. I'...

If your AC unit is a portable one, yes, it should work. By portable, I mean the unit is shipped with a 13A plug attached rather than designed to be wired in to a fused spur. It also depends on the size of the unit. If the compressor is rated at 1 kW or less, you should be fine. Equally, if it is a slightly larger unit, but with modern electronic 'soft start',...

I measured an IKEA TRADFRI control outlet (on/off) E1705 with a true-RMS multimeter. These are the results: - Relay OFF: 0.43 W - Relay ON (no load): 1.9 W

I would imagine the same restrictions would apply to Smart Plugs and any other electrical device equally; there does not seem to be any specific legislation that applies to IoT devices. The UK Government (which, despite the recent Brexit referendum, still respects EU law as of 2016) has published an extensive guide named Electrical equipment manufacturers: ...

I've got the TP Link HS110 myself. The appropriate connection is established via their app (called Kasa). The process is described here. Without diving into the French Amazon reviews I won't comment on "the critics." However, I've had no issues with these plugs. Having said that it is important to notice that most smart plugs from commercial sellers will be ...

Since you're interested in generic ways to connect devices to Alexa, I'll explain the two main methods that devices use when integrating with the Echo platform. Skills Most of the devices that have 'first-class' integration with Alexa have a custom skill. For example, the Belkin Wemo has a skill, and so does the TP-Link device you link to in the question. ...

Some smart plugs can be controlled over the internet without having to be on the same network. D-Link Smart Plugs (http://us.dlink.com/products/connected-home/wi-fi-smart-plug/), for example, have a linked app that allows you to switch the plug on and off from anywhere as well as setting schedules. They can also be connected to things like the IFTTT system ...


5

The Belkin WeMo sockets can also be controlled remotely from the app. Basically any socket with support for Alexa/Google Assistant will have cloud component to control them (because the smart assistants connect to a cloud end point to do the control). This means you can also use the Alexa/Google Home apps to control them remotely.


5

Sonoff do a range of smart sockets that can be flashed with the opensource firmware (though it does look to require soldering skills). Once flashed they can be controlled by either a local MQTT broker or HTTP request direct to the sockets. For straight off the shelf options: If you are happy just to ignore the cloud capabilities Belikin's WeMo devices can ...

I believe you don't need to do any coding effort on connecting smart-plugs to Alexa. http://www.belkin.com/us/support-article?articleNum=157351 This link contains all you need to set up the cooperation. You have to have one Alexa device, your first Wemo device and Wemo and Alexa apps (I suppose in your phone). You will have to setup the Wemo device and ...

In this case, the relay control is just a signal to energise the coil in the relay. It's likely to be a fairly high current (10s of mA) so needs a switching transistor in addition to just the mcu I/O pin (unless the relay is a solid state module, or has a local driver). Do remember that the components inside this switch all risk being at mains voltage, and ...

Bluetooth isn't very common in that area. Most switches use ZigBee or Wi-Fi. I assume that you don't want to interfere with the actual function of the half-hot in the first place. If you'd use this plug and this switch you could use IFTTT to have the plug activate whenever you activate the switch. However that requires an internet connection and that command ...
