@DBKAsa Following up on this, I have contacted support chat (very very slow and unknowledgeable). They have no answer. "rearrange the wiring", they said. How idiotic. The light WORKS, it's just slow. Rearranging the wiring will make the light not work, as electricity will no longer flow to the switch.

If anyone else here knows a solution for the issue, I'd love to hear it. Thanks and good luck to anyone with this defective product. I'll be posting reviews on Amazon and anywhere else I can think of about this situation.

@DBKAsa Had to sign up for an account just to confirm I experience this too. Way too slow on single tap. And what's absurd is that setting the double tap to instant actually does what you'd expect: near instantly turns on and off. Is this an oversight? Is it new with a firmware update? I can't seem to find anything about this anywhere else 

@Tim8480 It's definitely an oversight, and a big one. Somewhere else on this forum is a post where the user says they experienced it with hardware v2, but not v1.8. So I think it's a hardware revision, not firmware. That said, if it could be fixed by firmware that'd be great. Still, we should at least be able to recieve replacements.

@DBKAsa If only support had a clue. I mean "try changing the wires around" is literally the craziest thing a phone support person has ever told me. Yes, I'll risk my life by randomly changing some wires around to just "see if it works". Unbelievable. The unfortunate side of companies not based in the US is that there's no consequence for negligence...even if I literally shocked myself to death trying what they told me to.

@DBKAsa the fact that I can set "double tap" to "instant on/off" and the light IMMEDIATELY responds is a testament to the fact that it's possible to skip the single-tap delay. Unfortunately, doing so seems to instantly set the dimmer setting to max brightness? That can't be right? Your support story is hilarious by the way. 

@DBKAsa I have h/w 1.0 with f/w 1.5.11 and h/w 2.0 with f/w 1.0.4. All exhibit the same slow to turn on behavior. Tried messing with the minmum dimmed level calibration thinking it might've been something to do with that but it made no difference. 

Pressing "on" via the app has a shorter lag than the physical button....

@DBKAsa 

h/w 2.0

f/w 1.0.5 (recently updated through the app)

I am experiencing the same issue as pointed out by everyone here and am very frustrated.  Hopefully tp-link can give us a fix through firmware update.

@DBKAsa @JohnnyBoy22  @eneka  @Tim8480 

I figured it out (they do it on purpose)!

Here's the reply I got from support:

"HS220 has the function of single-click and double-click, so the action cannot be executed immediately after the single-click. It has to wait for a period of timeout to confirm that the user would not double-click before the action of single-clicking is executed.  So when the user clicks the button, there will be a little delay."

@DBKAsa 

Like @Park_29487 suggested, I sent them and email and I got a similar response. The delay is because switch is waiting to see if you're going to double tap.

The workaround they have me is:
"If you want the switch to respond immediately, you can set double-tap instant on/off..." "...as long as you double-tap it, it will respond immediately, but sorry, there is currently no setting for single-tap instant response, and we will give feedback to relevant departments."

 

@DBKAsa 

The solution to this is a simple fix that I cannot understand why it hasn't been implemented.

The understandable claim by TP-Link support is that the switch must first confirm that the activity is not a long press or double tap before treating it like a single press.   Sure, that takes time and it makes sense.

However, if both double tap and long press have been set to "None" in the app, effectively disabling them, then the logic should be to not require and wait for a confirmation of which activity occured. If the only viable option is single tap, then treat all activity as a single tap.
