Smart Switch HS210 does not light bulb
I have a TpLink HS210 three-way Smart Switch, all the switch boxes in the house have two-pole wiring, phase or positive (red) and neutral (white), there is no ground. I already did tests by substituting two switches for the three-way Smart Switch, it turns on, I configure it with the Kasa application and it connects to Wifi, but it does not turn on the bulbs (I have tried several), even the smart switch sounds when turning off or on the light with the application or with the same button of the switch. As can be seen in the photo, those are the device connections at the top Neutral, Ground and Line / Load, and at the bottom the two Traveler connections. The wiring connection I make to the Smart Switch is to neutral and Line/Load. Any suggestion? Thanks.
