@JingleDJ Thanks! I've done a bit more reading and experimentation and (along with some other suggestions from folk) I'm fairly confident about things. But it's not natural is it?! Basically, I still agree with this guy: https://www.reddit.com/r/homeassistant/comments/1c0qjo5/comment/kz0dtdr/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button
Anyway, it is what it is. No changing it now - although installing PyScript or AppDaemon is appealing (even though I've never used Python in anger (yet...) - I'd still be a lot more productive I think)...
