Wifi and manual switch fail to turn on power
My HS100 connects to Wifi and the power indicator light responds to remote on/off (changes color) indicating that WiFi is working.
However, there is no power delivered to the outlet (confirmed with voltage tester and multiple appliances).
Pressing the manual power button similarly changes the power button color but fails to turn on power to the plug.
I do *not* hear the solenoid/relay clicking -- neither when Wifi switching is used nor when manual switching is used.
I *do* hear a very, very, very faint momentary "squeal" (with my ear up to the plug) when the Wifi switch is powered on (like current energizing something).
A hard wack to the HS100 does *sometimes* power the outlet but the power only lasts for a few seconds.
I suspect a bad relay or perhaps relay driver... but want to confirm that nothing else could be causing the problem.
