@ [pedolsky: I spotted the reason it was just showing as idle. My timer is named timer.timer_meross_05 and not.timer_meross_05, oops!
It works and now shows the duration as per set on the Input number.
Different Issue now: It is interpreting the 1 miin set on the “input number” helper as seconds hence immediately turns off. Is there a way to have the timer see the number as minutes?
Ah ha, I fixed it by doing a quick search. I adjusted the Automation part.
FROM: {{ states(‘input_number.meross_05_on’) |int(0) }}
TO: {{ states(‘input_number.meross_05_on’) |int * 60 }}
Now to absorb it all and see what I can do with everything you both provided. Thank you so much, very much appreciated.
