Cygnett Smart Wi-Fi Plug with Power Monitoring $14.45 (Normally $34.95) + $5 Shipping @ Cygnett

180
COMEBACK15

Shipping free if spend over $50.
Fairly reliable smart plug, quite large though.
Can barely fit a normal plug next to it in a standard double GPO.
App control via Cygnett, EWeLink or Apple Homekit.
I was also able to get it working home assistant with the HACS custom component sonofflan. Energy monitoring also works (I use it to see how much power my dryer consumes)

  • Can barely fit a normal plug next to it in a standard double GPO.

    Is that a pros or cons?

      Not really a pro or con when every single brand has the same problem

        This isn't true. Quite a few add that bulk in length rather than width.

  • +2
    • Not if you want Homekit though

    • I have one of these arlec ones too and it seems to drop connection more frequently, YMMV.

    • $65 for 4 packs. Not worth it if I only need one.

    • I've tried Arlec smart plugs and had to return them as I couldn't get them to connect at all. I've had success with the Genio line and have a few of them now. Pretty happy with them

  • +1

    A bit off topic - any remote controlled plug that can be used outside? I need something for the pool lights.

  • I bought a couple of them when they were $14 at Woolworths. They are good and they can connect to WiFi directly without a gateway.

  • +1

    I found the meross ones really easy to set up and similar price:

    • I have it too and it works well. Buying 4 pack will save you most money and works out cheapest.

    • Only reason I buy Cygnett is the Apple HomeKit integration, which meross one doesn't have unfortunately

    • Damn I really wanted these but they also don't fit side by side in a double GPO according to FAQ :(

  • Lucky these have two year warranty. I had one that I had to return to Harvey Norman just before the 2 year mark.

  • t actually looks to also be the smart home range they have on sale, including globes and LED strips. https://www.cygnett.com/collections/smart-home

  • Out of curiosity, from a network security perspective, would you create a separate wireless network for these IOT devices and/or put then on a separate VLAN/rule?

    Alternatively, what is your recommendation for securing IOT devices?

    Feel free to add any further commentary on the matter :)

    • They need internet access so there's not really much point in my opinion.

      • Why do they need internet access? Do you know what happens if they connect to an internetless wifi?

        edit: I can see in other comments they can be remotely controlled via internet. But can't they just work and communicate with the app while in the same wifi, without internet?

        • +1

          I have no idea because the only reason why I, and I assume most people would use these is for Google Assistant etc which does need internet access.

          These days something that only communicates via LAN is very rare, I doubt it would but it would be great if it did.

    • Ideally they can't access your main network devices in a perfect world, but devices that can create VLANs tend to be expensive so I haven't got that far yet. I have a VDSL modem with a wifi network that is just used for IoT devices, then my main router is below that on a different subnet. That way I can ping devices on the modems network from say my home PC, but they cant ping me back unless that connection is already established. If you're very paranoid you can enable AP isolation which prevents the connected devices from even talking to each other, but in practice it makes them harder to troubleshoot and setup.

      Only issue you will have is with controlling devices (like casting, player controls etc) won't be discovered across the different networks unless you have some kind of fancy multicast repeater. I have a NAS running home assistant with 2 ethernet ports, one plugged into modem and one to router. This allows discovery on both networks, and I just block all the ports with a firewall rule on the modem side. Probably not ideal but it works.

  • I nearly bought one of these yesterday but found out you need an Apple Homepod to communicate with it from outside your home. Am I correct or not?

    • No these link straight to wifi and the Android apps allow cloud control out of the box. Maybe for the apple side of things you might (I've never used HomeKit).

    • That's generally how HomeKit works - you need Apple TV / Homepod (or mini) / iPad at home, to serve as hub for external control.

      Yes you're correct for Apple HomeKit.

      However, if using Cygnett's smart app, you can access it on the internet outside of your home. Google Home integration (which is available on iOS too) works the same way, by communicating through the Cygnett service. So with an iOS device, you could still avoid the need to buy any Apple Homepod.

      This does however mean that you are relying on Cygnett's servers, which could have security risks or obsolescence in the future (what if Cygnett shuts it down?). Even when you are home on your local network, Google Home still requires internet to function in order to talk to Cygnett's servers, instead of directly communicating with the plugs on your local network.

      But with Apple HomeKit, it is quite different, the smart plugs will integrate with HomeKit by directly communicating on your local network, which does mean to control them outside of your home, you need an Apple Homepod or Apple TV to act as the hub/bridge to open it to the internet. There is no involvement of Cygnett's servers when using them with HomeKit. This (imo) is better than Cygnett or Google Home apps, because it does not require internet connection through Cygnett's servers. And whilst it does rely on Apple's servers for external control, I think they are must more reliable and trust worthy than Cygnett's.

        Thanks deal-fomo, great reply.

  • I bought many of these last year as I had one which worked perfectly with HomeKit. I ordered 6 from Amazon Black Friday sale. 4 didn’t work and I got a refund. I have purchased Meross (HomeKit compatible) from Amazon and they are more reliable

    • but there's no homekit compatible meross with energy monitor, that I can see. What's yours?

  • +2

    I don't get why smart plugs are always designed so incredibly wide. Do they not have double GPOs in other parts of the world?

    • +5

      it's to block the adjacent outlets, to help you reduce your energy consumption.

    • Check out my comment for plugs that aren't so wide.

  • Anyone know if these work with Zigbee2Mqtt?

    I'm a big fan of these ATHOM Preflashed TASMOTA Smart Plugs. I got mine from AliExpress, but Athom appear to be having a sale.

    1 shipped from China is $18.80
    2 shipped from Australia is $34.60 (need to order in multiples of 2).

    • No need for internet access.
    • Work well with Home Assistant.
    • Can use the socket next to it.

    Edit: Oh … it's USD 😢

    • +1

      Yeah these actually seem to be the price they've had them at for some time.

      I have 8 of the ESPHome flashed variant. Been running solidly for months now.
      Highly recommended, worth the extra 5 bucks a pop.

  • Will those work with 5G home broadband ?

  • This week the v1 Matter standard was released
    https://csa-iot.org/newsroom/matter-arrives/

    Still trying to get my head around if I should pause hardware purchases for a bit, as the hardware vendors will start releasing matter compliant devices. I use home assistant, so can technically have a mishmash of brands/protocols but for futureproofing think I’m going to give it a couple of months. Anyone else got thoughts on this?

  • Im a newbie to the integrated world.

    With one of these can I use my Samsung phone to turn on/ off, say a lamp, from my phone (in house only or while out and about)?

  • Anyone know how much power this smart plug draws when idle? Looking to place it in a hard to reach socket to turn off devices drawing vampire power.

  • +1

    Received mine today. It’s wide, but the plug is offset to the left when looking at the front.

    So if you plug it into the right of a 2-gang wall plate, you can easily fit something else to the left of it
