HS200 Wired Correctly, but light won't turn on/off
I'm baffled. I want to install a Kasa HS200 in place of a mechanical switch to operate a ceiling light. The existing installation has 4 wires - black, red, white and bare copper ground. The machanical switch wires were connected as follows (looking at the wall): Black wire to top right connector on switch, white wire to bottom right connector, red wire to top left connector.
On the Kasa, I tied the white wire to the existing white wire, the existing black wire to one of the black wires on the Kasa, the existing red wire to the other black wire on the Kasa, and the green wire on the Kasa to the existing bare copper ground wire.
I connected the Kasa to my network with no problem. I can use my phone or press the Kasa to operate the Kasa, and I hear a click from the Kasa and see the indicator on the Kasa switch states. All good. However, the light the Kasa is connected to doesn't come on. I pulled the Kasa and put the mechanical switch back in and the light works as it should. Reinstalled the Kasa (checking carefully to make sure the connections were solid) but the light still doesn't turn on.
Any suggestions on something to try?

Same issue. Tried everything else as others mentioned. No resolution.
Is it really possible that the switch does not provide enough power? That seems ridiculous.

@Engineer_Dan Same problem here. Got the switch installed and set up in the app. It works with Alexa and everything. But it just doesn't turn on my light. Using a single-switch 72w halogen bulb, btw.

@gpg UGH! I get it now.
I only have two wires in the box. But the switch requires 2 black wires and the neutral wire. This allows for the switch to be powered separately from the light.
Since my building is old (like most houses/apartment buildings) this switch will never work with my lighting system unless I get an electrician to run some wiring (not worth it). What's more, TP Link doesn't have (nor does it ever intend to have) a smart switch capable of accommodating my requirements.
It would be nice if sellers would plaster "NOT FOR OLDER BUILDINGS" on the product page. Fortunately, I got it on sale, so I'll consider it a $12 lesson. Not that unreasonable.

@gpg - pretty much all the ads I've seen state clearly "Neutral Wire Required" - Certainly Amazon does

@Jackiesmith I have the same problem. I tried two different Kasa switches of the same model and no joy. The dumb switch does work, however. Is it possible this was wired as a three-way switch but no other switch is actually in the circuit? There is only one light switch for my garage but I too have the same wiring that you describe with the red wire coming off the cluster of black wires.
I have successfully installed several switches that work fine in the rest of the house. One of them-there wundements! LOL

@Engineer_Dan Same issue here. 1st nothing worked so I swapped the wires which are 2 black ( well one looks dark grey). I have a neutral wire too single pole switch. Once swapped, the the lights turned on and dimmed for 2 minutes. BUt now the LED ligths do not turn on at all. Only the wireless portion is working and resonding to my phone. But no lights ever turn on now even thoight they did at 1st. Support says its the wiring, we red it ia ll again. Same issue. no lights only wifi activity. WHat next?!?!

My problem is that it doesn't work with LED bulbs, they either strobe, are dim or not work at all; I have tried at least 5 different brands of LED bulbs, dimmable or not.
I have no such problems with my Lutron Caseta switches (16 of them!), only two rooms in my house don't have them yet.
I wanted to try these since they are 1/3 the price but I guess you get what you pay for...
And of course I missed the return deadline on Amazon, so now I am stuck with it.
