HS210 3-Way Smart Switch - No Circuit Status Feedback on App or Switch LED
I recently installed six HS210 3-way smart switches in our home. Four of them are in a four-gang junction box and two of them are in a two-gang junction box. All of them have hot lines (black) connected to them. They are all single-switch installations (one smart switch on only one end of each 3-way circuit).
Five of the six HS210 switches work perfectly (three of the four switches in the four-gang junction box and both of the switches in the two-gang junction box). Those five switches turn on and off via the app when the power button is pushed and the status of the lights are also reflected in the app. Those five switches also properly turn the lights on and off in the circuit when pushed, with the LED on the switch also properly reflecting the status of the lights (LED off indicates the lights in the circuit are on and vice-versa).
One of these HS210 smart switches, however, is not working properly. It will turn the lights in that circuit on and off at the switch, but the LED on the switch itself will remain lit. Also, when I press the power button in the app, the switch does cycle on and off, but it does not show the status of the lights in the app. It always appears as if the switch is off.
I have reset the switch and the problem still exists. I have also toggled the other non-smart switch in the 3-way circuit to both positions and the problem still exists.
Might this particular switch be defective?
I love the TP-Link switches and am in the process of converting our entire home to them. I have already installed a combination of 24 single-poles, dimmers and 3-ways and have more on the way. I also have a very good understanding of electricity and home wiring, but I'm not perfect (just ask my wife ).
Thank you, in advance, for any feedback you can provide!
