@dafish,

As far as we are aware, the KS230 will not work in a 4 way circuit. Officially, we only support the use of our switches and dimmers in a 3-way configuration; but you can find threads from other users across the forum, detailing how they got different products to work in a 4-way circuit. You will most likely find that other products are far more suited for 4-way circuits than the KS230. I would recommend taking a look around, as some of our user's knowledge in home electrical wiring surpasses my own by far, and oftentimes they provide diagrams of how they wired everything.

As far as how the dimmers function, the satellite unit will pass dimming signals to the main unit, and the main unit is the only device actually controlling the flow of electricity to the connected device. Placing an additional dimmer/unit in between the units will prevent the signals from reaching the main unit. Dimming Signals are a very bizarre topic, and is also the reason why our dimmers are not compatible with some dimming types.

We are looking there is just a lot to have to look through. if you need direct support from the team, it is always best to email or live chat with the support team, as there is no guarantee that your post will be responded to throughout the communities, or in a timely manner.

As for version differences, especially Smart Home - there is often very little difference between versions. The jump from v1 to v2 was unique in that it did change the wiring of the device and made a lot of improvements on the hardware side. Smaller Hardware Updates such as 2.0 to 2.6, will be the same and will usually share its firmware - oftentimes, this change is triggered by a simple change in manufacturing location.

I do not currently see a v3 model listed on the site for available firmware downloads. I would assume that there should be no real differences between the v2 and v3, but I will try and look for specifics if the version does exist. At an Amazon level, the older v1s, with the older wiring system, are listed as an older or classic style - new postings for the KS230 will generally use the newest versions, but you can check the wiring diagram in the listing to confirm.

  @Super_Man_007,

Apologies for the experience you had with the V1. The V2 was really the model that you are looking for in terms of improvements; looking at our internal documentation - there is no difference in the setup and operation of the V2 models.

The V2 had many improvements over the V1 (a few are mentioned in the original post of this thread) and basically fixed all of the reported issues from the previous version, as this was the purpose of the V2 redesign.

Is there a specific part of the original version that you have stuck in your mind that i may help put to ease?

What type of wiring setup are you looking to install a switch into?

Also, I will probably be just as vague regarding the V2 differences. The smaller updates for models are often minimal changes, such as a change in retailers or manufacturing locations. If there were any hardware differences between the V2 revisions, they would be so minimal that they would likely go unnoticed by users, and this is the case for a large portion of our Smart Home Products with multiple sub-versions.

In my opinion, as I have these installed in my home, you would be best to ignore your experience with the V1 and look at the features of the V2, along with some of the other posts on this forum detailing their setup.

  @Super_Man_007,

Unfortunately, as long as the switch is in working order, it is not eligible for a warranty return; you would need to check to see if you may still return through however you purchased the device.

All Kasa switches use a standard wall plate size, for some KS230 there may be a small gap between the plate and the switch - but this should not cause the reset button to be pushed. Are you positive that the switch is properly aligned to the wall box, and your wall plate uses standard decora sizing?
