Hi @Ze_Pico, I’m making some fairly substantial changes to my Node-Red setup in Spain at the moment (in between doing some plastering, painting and electrical work), so I’m not going to import your flow into my system at this stage, as I don’t want to risk breaking anything.
Considering what it is you’re trying to achieve, including the integration into numerous other systems, the flow looks well structured and straight forward. It looks like you’ve made quite a bit of progress!
It might be worth you re-reading this post:
Especially the bit about how I did the countdown timer and how the remaining time in minutes and seconds is calculated and outputted to a widget to display the remaining time. I used a switch widget for that, but you could use a labelled display if it works better for you.
Pete.
