First : I delete the Homey Hue Lights -> And retain the Hue Hub Lights
Homey Hue Lights
Alexa -> Server -> Homey Server -> Homey -> Hue Hub -> Light
Hue Hub Lights
Alexa -> Server -> Hue Server -> Hue Hub -> Light
One whole less jump, which can be significant especially when Homey Server(EU) is on one side of the word, the alexa server (US) on the other - and I live practically in an different universe (AU).
Second : If you decide to do the same then you need to be aware that the Homey Skill while stable is half-baked. So it is not possible stop a device being imported and further to that as soon as you delete a device … it is re-added. So Instead of deleting the devices you need to disable them in the alexa app.
Third : When attempting to turn on/off a device using Alexa if there is a disabled device of the same name Alexa will tell you she cant comply. And she can easily get confused so you will have to be extreme when renaming the device to stop this. I Found "x[emoji] - Homey - Hue - Disabled - Lounge Light " seems to work .
Forth : I’ve found that there are also sometimes issues with the Rooms imported from the Hue app, and naming them as “Hue in Lounge Room” rather then “Lounge Room” seems to help - this is an issue for me in particular as I have ZWave lights. So I can “Turn off all Lounge lights” as well as “turn off hue in lounge”
Fifth : I use the group app to named as "All Down stairs lights’ To allow me to turn off items not grouped in the hue app.
Hope this helps.
