    Good for flashing with ESPHome/Tasmota and using them locally with Home Assistant :)

        It's been a while so I can't remember specifics - and didn't take notes - but this seems similar to what I did https://blakeniemyjski.com/blog/securing-smart-home-devices-…

        tl;dr - use a Raspberry Pi execute tuya-convert which hosts an SSID, plug connects, tuya-convert flashes firmware, plug joins your regular WLAN
        (pinouts are here https://www.esphome-devices.com/devices/kogan-smarterhome-sm…)

        • Borg on 07/01/2021 - 16:48

          Would I be correct is saying that this only permits controlling them but does not show the "Live Energy Use" of each plug?

          • The 10th Doctor on 07/01/2021 - 16:52

            @Borg: Negatory, it exposes the value in HA and you can do whatever you like with it. I do some rudimentary tracking but it's harder to estimate my costs as I'm with Amber Electric (TOU plan) https://imgur.com/qMBQU8f

              @The 10th Doctor: These for me at least, are only good for calc approx costs of certain areas, e.g. I connected the fridge to one for a week or so to get a guide of avg use. I do the same for certain sockets in the home that may have a powerboard attached. Now I have a 95% guide as to what is being used where.
              I don't leave these in position permanently unless I do want to use the On/Off capability.

              For Time of Use power (TOU) grab yourself a PowerPal device which attaches to the power meter (if in a house), this way one can monitor the whole house to get a better guide over totals live. 60 days of data can be exported and is by the minute! They work well if one is interested in seeing how much power is being used and at what times.

      i dont think these can be flashed OTA anymore with the update tuya firmware. will have to open them up and do it which i think is quite difficult with these

    • Domingo on 07/01/2021 - 17:56

      I bought two packs about 2 months ago, definitely can't flash them OTA for tuya-convert. The firmware they come with hides the encryption key, so they can't be written to.

      See here: https://github.com/ct-Open-Source/tuya-convert/issues/483

      • [Deactivated] on 07/01/2021 - 22:55

        Did you crack them open and find the points to solder to?

        I did 2 of the Kmart ones the manual way, they have annoying 3 pin security screws that I had to drill out

        • johnmelb on 07/01/2021 - 23:15

          I read these were glued together and almost impossible to open.
          Not sure if there are people here with experience.

    excellent product.

    Just wished the "Smarter home" app that control these showed Power Use for all on a single page. Currently one has to first select the plug, then the Energy icon. If one has many plugs it's a pain having to back out of existing plug to then view the next. I'd have bought more if that feature existed.
    Plugs are decent enough though, especially as they are slim and can be plugged in next to each other.

    • Domingo on 07/01/2021 - 17:58

      I'm using the Smart Life app for mine rather than the Kogan app, but same issue.

  • craigmate on 07/01/2021 - 17:59

    I purchased these back in May, I was able to flash them and put on ESPhome, They are great as they have wattage, voltage, uptime, etc. However I think what tbar05 is saying is correct, they can't be flashed OTA anymore. A few people on the home assistant forum tried lately and it failed. They also tried to open them and it was quiet difficult, and the chip is not easily accessible. If you are happy using the cloud, these are certainly good value, but for local control I think they are not as useful as previous.

  • TomGum on 07/01/2021 - 18:01

    These do make a slight noise if you put your ear next to it.

    • Borg on 07/01/2021 - 19:19

      I just checked. I thought they were silent BUT with ear right up to them they do indeed make a very slight dull hissing sound. Not something one would hear without ear right up to them. Why…….does this represent something bad like crap capacitors or the likes?

      • TomGum on 07/01/2021 - 19:43

        Cheap parts. I have another brand and that makes no noise. But I don’t know if the noise represents a hazard….

  • johnmelb on 07/01/2021 - 22:02

    These can't be flashed anymore with tuya convert.
    Also don't expect to get lucky with old stock, because it seems Kogan had old stock reflashed too.
    (My box came with 2 labels last time).

  • donm on 07/01/2021 - 22:51

    Fantastic pricing. I'm probably being silly, but I'm hesitant to buy WiFi smart plugs. Zigbee seems like a better communications technology for home automation, since it requires less power, forms a mesh network and won't affect your WiFi network (or does it? Both use 2.4GHz). I already have a Raspberry Pi with a Conbee II stick and Home Assistant. The cheapest ZigBee smart plugs seem to be about $40 and don't come with USB ports or energy monitoring. Maybe ZigBee is a better technology but WiFi will be dominant because it doesn't need a hub. Is it a case of VHS vs Betamax?

      These Kogan plus aren't that good for power monitoring.
      None of the Kogan plugs I received detect the devices that consume 4-6 Watts.
      However, the HS110 plugs that I have, do.

      • Borg on 08/01/2021 - 00:29

        I noticed that with one that I have. The Fridge when the compressor turns off it shows 0 watts but should be showing around 10w but doesn't. With compressor on shows around 110watts. Have yet to test using another one. That's not good and could be considered faulty units especially if one was monitoring for Standby power.
        The question is whether it records the data in the daily totals (I wonder). More testing needed.

        A second (have x4) unit I have has no trouble with small watts. Shows 3 watts etc.

        • skid on 08/01/2021 - 07:15

          If you have them flashed with tasmota, there is a calibration procedure which might make them more accurate: https://tasmota.github.io/docs/Power-Monitoring-Calibration/

          I find that devices that do not draw a resistive load are hit and miss on any power meter below 7W.

          • johnmelb on 08/01/2021 - 13:59

            @skid: I tested the exact same device again just now.
            It definitely shows the power consumption with HS110 , but 2 of the Kogan plugs I tested now, do not show it.
            The other 2 are connected to other devices and don't want to unplug them again (as I've already tested before and they also do not show the power consumption.)
            One of those Kogan plugs is connected to a security cam consuming 4W during daytime and roughly 6 during night time. Kogan plug doesn't show power consumption at all.
            Previously I had a hs110 there, and it showed power consumption 24/7.

            So for me a major difference between quality of the Kogan vs TP-link plugs.

            Unfortunately can't flash the Kogan ones, as they have updated firmware.
            I bought the Kogans because they don't block the adjacent plugs, but was expecting that it would pick up something for the low power devices.

            • Borg on 08/01/2021 - 14:58

              @johnmelb: If Energy Use is important, then one could return as faulty. If just for manage On/Off or timer power etc, then still reasonable value regardless. It's how I see them. Would be nicer if they just worked as advertised.

        • johnmelb on 08/01/2021 - 14:14

          It also doesn't pick it up in daily stats.
          I had 1 security cam connected and after +-18 hours, the daily stats still show 0.00.

          I also have 4 plugs at home, none of them are picking up the small power consumption.
          I initially thought something was wrong with the home assistant integration, but after a bit of testing came to the conclusion it were the plugs that didn't report anything (confirmed by checking directly in the tuya app).

          • Domingo on 08/01/2021 - 16:57

            @johnmelb: I wonder if it varies from plug to plug - mine picks up my christmas tree lights which draw 4-5W and used a grand total of 0.4kWh in December.

            • johnmelb on 08/01/2021 - 21:38

              @Domingo: Might be, but I've got 4 Kogan plugs and none of them pick it up.
              2 HS110 do pick it up.

              If there's such a big difference between Kogan plugs, then that's a serious quality problem.

    RRP keeps changing too, dodgy Kogan practices.
    The 4pack was $56.99 , then discounted to $39.99 with RRP $59.99.
    After the promo they went to $59.99.
    Now discounted again to $39.99 but with RRP of $79.96 ??
