HS210 3 way light turns on from only one side
I've just installed the HS210 3 way on both sides of my 3 way switch. I'm pretty sure it's wired correctly, but would always appreciate validation for it.
I've wired both black wires into the 2 black screws on top. I've tied together the white wire and ground wires with their own wire nuts and the red wire on the side screw.
The behavior that I see is that whichever side turns the light/switch off, has to then turn it back on. For example, if I turn on the switch on switch1, then turn off the light with switch2, switch1 cannot turn the light back on. Instead, switch2 has to turn on the light.
Is this expected behavior, or did I miss something in wiring?
