Post an example of the value of sensor.meteossstarttime. We need to know if it contains the date and time or just the time and also how it’s formatted.
Is input_datetime.economy_7_start configured to simply store the time or both date and time?
As for the automation, it will simply have a Time Trigger set for 22:00:00 and will set the Input Datetime to the sensor’s value.
Sorry I have started another post, did not notice this reply & was trying to be more specific
I think it is a date/time issue and my data is text perhaps
sensor.meteokensstarttime is pulled from the text file
input_datetime.economy_7_start
I currently manually change in a card, this triggers an automation and a script that simply sends this value to my solar inverter & does work, does not seem to be an issue text or time here.
