I just installed the latest firmware this morning. Now, when I ask Alexa to turn on a light, the light goes on, but Alexa does not say "OK" but tells me something went wrong. So we can still turn on and off the lights, but it appears Alexa is not getting a confirmation. Not sure if it is the HE or Alexa.
Do you have the Echo skill option set to not wait for device response, if you turn that on it will probably fix most of your problems.
I will take a look and give it a try.....thanks!
Thanks, that change apparently did the trick...thanks!
