Actually… It is possible. But you have to use the IFTTT integration, just as you would with echo.
On the SmartThings side, you assign a virtual switch to run a routine, and that routine can change the mode. Or arm smart home monitor.
Then you have your IFTTT applet turn on the virtual switch when the pop button is pressed.
Here’s the FAQ for how to do that. Although this is discussing echo, it’s the same process for the pop switch.
Of course this assumes that the IFTTT pop service/channel is available in the UK, and I haven’t confirmed that. please let us know if it isn’t. The UK page I link to above which describes the specifications for the pop switch does say it has IFTTT integration, so it should work.
I’ve just installed one of their brushed chrome light switches in the kitchen to control dumb downlighters. Works fine from Alexa/app with occasional lag. Also has on/off manual button and status led. You’ll obviously need a hub so either buy an energenie hub on its own or hub & plug adapter kit too… Main thing is it’s pretty cheap! I have experienced some random lag with some of the plug sockets though… But light switch seems fine. Allows you to convert dumb UK lighting to smart lighting at least! Oh and make sure you install it as a light switch in the app, it looks just like the relay picture but the images are out of date, it is definitely a light switch!
There is no slave switch available yet for Energenie.
I believe there might be one coming.
Lightwaverf are another series of switches.
These like the energenie need there own hub for ST integration.
With Lightwaverf though, you can integrate with a raspberry Pi to act as a server and then integrate with ST to give minimal lag for automation.
I have Energenie here, albeit the plugs (not sockets). I added the Device Handler, and now run from ST with minimal lag, its all working quite well, and the Handler does a great job.
I also have LightWave, had them ever since B&Q started stocking the Siemans model years ago. Sadly I cant get that working through ST, no matter how many times I tried, so gave up. I’m sticking with them though, as their dimmers are great, sadly quite a lag through Alexa though as you’re always treated as remote. I really don’t want to go down the route of PI, even though this would remove it. I simply don’t want yet another hub
Apparently Energenie will be releasing more products this year, I’m holding out for this as their pricing is pretty good in comparison to others.
Maybe I am missing something, but wouldn’t the simplest solution to the two/three wire problem be a light switch with a built-in battery to accept commands when the switch is off? Thereby bypassing the need for the neutral wire.
There are some good battery powered switches, but they don’t actually control the current flow. They just act as wallmount remotes. In the U.K., Devolo and Popp make nice versions of these that will work with SmartThings. But then there has to be some device which actually does cause the lights to go on and off. It could be that the lamps themselves are smart or it could be and in the wall micro, not battery-operated, installed in the ceiling Rose where there typically will be a neutral. So the switch sends a message to the SmartThings hub which then sends the message on to the device that does control the brightness of the Lamp.
Note, though, that all of those are “surface mount” devices which are mounted on top of the wall, not inside it.
The reason why we can’t just hook a battery to the radio that is inside the wall is that pretty much any battery-operated device inside the wall becomes a fire hazard. Safety codes generally prohibit that in both the US and the UK.
Thanks, I have seen those, however, the problem as I understand it is that UK 2 wire systems leave the switch with no power when the switch is open, hence it cannot “listen” for the command to turn on the light. If a battery was incorporated into the switch to power the zwave device when the switch was open, it would solve this problem. Allowing a “normal” current control. The Lightwaverf dimmer seems to be the only other option apart from a device similar to the Fibaro universal dimmer and potentially deepening the patress. However, the Lightwaverf dimmer is only rated to 250w, I have 8 x 40w on one dimmer. I was simply exploring the feasibility of a 2 wire switch controlling the current with a built-in battery handling the zwave.
That’s correct, that’s why there has to be an additional device involved, either an in wall relay at some point on the circuit where there is a neutral, or by using a smart bulb such as a Phillips hue.
The Fibaro in wall dimmer micro can be used with just two wires, so it’s a popular solution, but as you noted, it’s not just the neutral that’s the issue, it’s also the size of the pattress box.
a battery was incorporated into the switch to power the zwave device when the switch was open, it would solve this problem.
Putting a battery inside the wall solves the problem of powering the radio, but if you burn down your house it’s not really an effective long-term solution. Our goal is never just to make a single light turn on–it’s to safely incorporate home automation controls into your overall electrical system.

There are some additional options. A common one is to put the micro at the ceiling rose rather than at the wall switch. There’s almost always a neutral there.
Another option is to use the energie or Lutron switches with one of the community created methods, although at present both of these require also using a “man in the middle” server device, typically a raspberry pi, and that requires more effort and technical set up than many people want to do.
Just this month at CES 2017 and official SmartThings/Lutron integration was announced, with the lutron staff saying they expected it in place by March. If it does arrive in that timeframe, that will provide another set of alternatives.
But for now, the most effective may be just to consider putting a micro at the ceiling Rose. That will give you a choice of more brands, as well.
I think you’re right. There’s just no standard that currently allows for this right now. Automation is still a relatively niche industry, hopefully if it becomes more mainstream, then standards will be created that allow for safe inclusion of batteries for such use.
The smoke detector is also a surface mount device, it’s not sunk inside the ceiling.
You asked why Z wave light switches don’t just have a battery inside. The answer is that the ones that are surface mount devices can. The ones which go inside the Patress box inside a wall would not comply with safety code. There are actually multiple technical reasons why this is true, but the fact that it’s true is why those devices are not on the market.
I have just had another thought. My main problem is both only 2 wires (solution dimmer in ceiling). The other problem was that the current set up is 8 x 40w too much for the Fibaro 2 (250w), the 1st generation Fibaro has a 500w rating, but very difficult to find in the UK now. The obvious solution came to me today. Bit slow, I guess, replace existing 40w with 4w LED’s! Job done, now I can use the second generation.
Does anyone know if the new Sonoff pow switch could be used to emulate an inline relay to control the lights but know the state, so that it could “interact” with the physical switch on the wall… I know there are a few rather dull looking zwave light switches that will run if you have a neutral wire. (I am lucky i do) and i know there is an expensive relay that will do it from Fibaro i think, but i want the affordable option. (i will make an informed decision on the safety merits of one of the newer sonoff devices in good time) Replacing with a sonoff touch is one option for some lights, but not good for 2 and 3 gang etc… I want to be able to purchase a nice standard brushed silver light switch and use a relay… (either momentary push switch, rocker or switched style) (the sonoff pow is a bit big so that might be a prob, if it it could be setup to work )
any thoughts would be appreciated… read too many forums and have lost the plot on this topic in the last few days, but still learning. I am a newbie to HA
The Sonoff pow switch is an inwall Relay, just like the Fibaro micro, it’s just using Wi-Fi instead of zwave. It says it’s CE certified and it’s not using a battery, so it should be fine as far as safety goes. It works exactly the same way as the other inwall micros, so you can use it with an existing switch, but it’s still going to act as a momentary, so the switch may not work quite the way you expect.
I don’t know if it has an open API, so don’t know if there’s going to be any easy integration with SmartThings.
Here’s an article from a guy who did an MQTT/Thingspeak integration, but it’s very technical:
@erocm1231 has done a lot with Sonoff devices, he might have more to add.
Also, since it can be hard to be really clear on all these technical distinctions, I’m not saying that you can take anything with the CE Mark and put it inside a wall and use it safely. Rather that a device that is intended for in wall use, like this one, will be rated for that purpose when it receives its CE Mark authorisation. I hope that’s clear.
Thats all clear , thanks. I know it can be used like a normal relay, in parallel. But what I am trying to establish is … with an appropriate device driver, and the correct wiring, can it be setup to work in conjunction with the physical switch, so if the physical switch is on, it knows the state (using the pow capability) and vice versa if off, eg read the power consumption to establish what state it is in (now i know with some “official” expensive solutions i think they are using this technique, but it is not working on low wattage leds, because of low current.) Then if i switch on via smartthings, it will turn off if physical switch is on (so would need to work like two way switch i guess, or a momentary switch with latch relay maybe ?
trying to understand the art of the possible, with limited knowledge at this point and dont want to reinvent the wheel if it has been done or is being planned… … (a low cost version i mean)
folks have connected these to smartthings , so that is doable i believe via wifi.
yep, i was coming to the conclusion it would only be suitable in the ceiling. Can you give me a pointer on how it would need soldering. I am assuming the normal pinouts wont be enough to connect in the way i want and therefore would need to pick up off the relay or something else on the board ? thanks
But why not make a switch that is effectively a Fibaro Micro Switch with front switch? all powered .
Or a Devolo that can be optionally wall powered instead of battery for those wanting a permanent maintenance free switch?
Personally I would like to see a Devolo style switch that has a built in connector to permanently connect the light socket to turn it in to an always on with an emergency slot maybe for some compliance to kill power.
That way you have no batteries, you use the existing hole in the wall and you keep the look of a normal switch.
