I use the HS210 in a single pole configuration as it was stated on the Amazon product detail page that this is supported.

I'm switching an outlet.

Now I have observed the following issues.

When I turn off the light the switch and the app still shows the light is on AND the load has still around 70V.

When I plug in a load the button status LED is toggling usually once or twice.

I know many here explained why it shouldnt make a difference when using the HS210 as single pole but something is off. Also not having a second switch here should be equevivalent to no connecting a second traveler.
