I just installed an S515 on a 3 way at home. Left the dumb switch on the LOAD end, installed the S515 on the LINE end.  

 

If I power off the lights from the dumb/load end, I cannot power them back on from the smart/line end….

Any ideas?

Did the Tapo S515 shut down as well when you turn off the light with the dumb switch? If that's the case, you may want to check whether the neutral line is connected to the dumb switch as well.

 

Double-check the wiring of the traveler lines. You can try to use a dumb 3-way switch to replace the S515, check whether the same thing still occurs.

  @Wayne-TP If properly configured should the S515 be able to turn the fixture off and on even with the dumb switch in the off position?
