Okay fell like I am starting to get back on track:
Q - Do you have to restart HA everytime you update the configuration.yaml?
Sorry looking back at your post:
Do you mean the section: HomeAssistant Names and IP Addresses?
If so what do I put in Name? I have installed hass.io vanilla.
What do I choose for Dim Controls currently set to none do I change this to pass thru?
I have managed to get through with name HomeAssistant and added and tested the three switches.
I unlinked as you said which worked but there is 6 devices switch.boys_aircon x2 switch.boys_foxtel and 2 x switch.boys_tv
Why is this? is it one for on and one for off?
How do I delete these and start again?
Thanks for your help I think I am getting close.
Edit: Sorry I assume I select Philips Hue in Google Home and pair which works. Then I get double ups.
