What is wrong with this simple script that triggers every hour?

Configuration
,

I wrote a script that sets a percentage to my blinder every 30 minutes.

here’s the trace:

Executed: May 16, 2025 at 4:32:13 PM
Error: Error rendering data template: TypeError: Type is not JSON serializable: LoggingUndefined

it’s sending no position. The only way this can happen is if the script triggers 1 or more minutes after the current_time, as in that case the position is going to be undefined. Is it possible to happen? Could it be that my raspberry pi 5 is so slow that it takes more than 1 minute to trigger?

I’m not 100% sure it’s your problem but have you thought about using the time pattern trigger instead of specific times?

3

You don’t have an else statement and if you’re testing it, the template will produce an empty string for the position.

It’s not super likely, but it is possible. To guard against it you can use the variable trigger.now.
