hey Matt, I've loaded up your flow but i can't see where to inject my long and latt as the first node is "true" rather than a field to add in long and latt
Thanks!

Great video, but my god! What a lot of crap to get sunrise and sunset... Why are you using Node Red over the bass HASS automation conditions?

First of all, thank you for all your good stuff on this channel. But in this video, I do not understand the point of all your calculations. In javascript, a Date object is in UTC so there is no need to try to convert a date for a particular TZ (if node-red knows your TZ via TZ=Europe/Paris for example). Take the API information as-is (UTC), create a date object from the string (for example, const sunrise = new Date and compare it directly with date.Now() will work. Like date.Now() or new Date() will also return a date in UTC (and not a CEST date or whatever), there is no need to do all of these calculations wherever you live. But maybe i'm missing something....
