The electrician came yesterday and fitted the wiring and first lot of plastering. He's back on Monday to finish plastering and fit the light fittings. As such, I've set up the Hue in readiness using a desk lamp.
I've got the above 'on at sunset, off at 10pm' set up natively through the app, which surprised me as I thought I'd need some help from IFTTT.
Also, currently out in the village, I'm getting the No Hue Connection warning, but no more info. As best I know, it's all on at home. Any ideas?
