I am very happy with homey.ink. Its is working fine on my google hub. Below you can see a screenshot of what i have now created with all the tips in this topic, elsewhere and my own. Thank you all for contribution!!
I do have some questions though;
I am running it localy on a Raspbery Pi which i also use for P1 monitor. Works great!
But how can i upgrade it to a new version without losing everything i added myself?
Also, i see in this topic a lot of more features, like sunset/-rise, settings, notifications etc.
I would love to have those features too. How can i add them?
As far as i figure it out, only the live time which was noted here as a good explained script and therefor it worked in 1 try. But none of the others i understand how to get them to work.
Can someone explain how it all works a little more in detail?
