By default, automations only have five Traces. Sometimes this isn’t enough. While you can change this for each individual automation, it would be much easier to have a global setting. Traces are super helpful for troubleshooting automations.
Can you point where is the number of trace selector ?
Seems to be super useful indeed.
In any automation, click Traces in the upper right. You may have to click the three dots to see it.
That doesn’t answer the question. Your original post says it is already possible to change the number of saved traces, just not on a global level but only for each individual automation. He asks where is this setting hidden. I’d like to know too because I can’t find it either.
My answer corresponded to the question that I thought was being asked. If you’d like to change the number of traces on a single automation to 20 for example, add the following to the YAML for that automation:
trace:
stored_traces: 20
