Hello,
I have the same problem as described in this post
https://community.home-assistant.io/t/input-date-time-format/34838
Unfortunately the solution given in this post (dec 2017) does not work actually with latest Hassio version.
{{states('input_datetime.start6')}}
{{ states('sensor.time')}}
1 gives format : HH:MM:SS
2 gives format HH:MM
So impossible to compare the 2 states
How can I format the input_datetime to HH:MM ?
Thanks in advance for your attention
Patou
