Cron json as variables

General
1

Hello I´m using some cron with fix values.
I want to refer to two Dashboard object for both variables toGrid and toSolar to adjust these values easier.

How is that possible?

Cron field:

{"toGrid":20.3,"toSolar":22.0}

No answer here? Is my wish not possible? Maybe there are better solutions as my?

cronplus is 100% dynamic. Your dashboard would need to "create dynamic schedules".

Alternatively, you could use a change node to update the values to those created by your dashboard.

e.g. cron-plus --> change (update msg.payload.toGrid, update msg.payload.toSolar) --> next node

Alternatively, you could use a JSONata payload and dynamically create the payload using $flowContext for example!

Thanks for your feedback. In the meantime I thought it would be better to have a number from an MQTT device. But how I can integrate any number in the cron?

5

store the number in context

retrieve the number from context - use a change node or the other methods mentioned in last post.

OK thanks I will try that - I´m not an expert, but I do my best :wink:

Have Cron-plus inject a simple message at your sheduled times.
Use a change node, or other means, to insert the current values for msg.payload.toGrid and msg.payload.toSolar.
