I've installed two HS210 three-way switches. At one location, the switch is completely inconsistent. Sometimes it works, sometimes it doesn't. Thinking I had a switch problem, I swapped the switches but even when swapped I got the same behavior at the same location. So is there any wiring issue I should check for? What is also weird is that sometimes, when the switch is not working, if I turn on the light using another switch (not a smart switch) on the same circuit, the HS210 will then work for a while.
HS210 works sometimes doesn't work other times
