The Timer with UI feedback is progressing. I used 4 such times in a flow. The timer is based on scheduler of BigTimer by Peter Scargill.
Now I’m adding “Correction” control. It’s a numeric UI input which should shift the end time of all 4 schedulers proportionally. This is simple function to implement - not a problem.
Practically, I tested, if the flow.json is changed not via web-UI then node-red asks to merge it. It merges the change successfully and all is fine. So this is the method I’m going to implement: regex which changes the json and reloads the node-red.
is there better/simpler solution to the simultaneous change of internal node value of multiple nodes in the flow not from WebUI?
Maybe this topic should go to Dashboard branch?
