Morning all, I'm new to Node Red so sorry if this is a dumb question. I am controlling a solenoid to come on for 500 milliseconds and go off for 20 mins. This all works fine. I would however like to allow a variable time to be entered from the UI to set the 20 min wait time. I've tried to upload …

One way would be to replace the repeating inject with a function node containing a JavaScript setTimeout function.

Grigsy, Have you had a look at the BigTimer contrib node ?

Morning all, Thanks for your feedback. I have had a look at the suggestions above but not really go anywhere however I have had a play with the change node and I am very nearly there. For context I am trying to allow for a time to be selected in the UI that will set a timer for the drum on my pon…

Unfortunately your flow isn't currently importable.Please read the following post How to share code or flow json and then edit the above message.

[image] Grigsy: if I change the time, it runs two different timing intervals. You will understand the issue if you debug the property msg._msgid in the output of your delay node. What happens is that each time you change the time you are introducing a new message in your flow. These messages…

Hi Andrei and thank you for your response. I understand that I am sending multiple messages that never run out my issue is I am unsure how to resolve the problem. I have tried addiing a change node and setting the global.delay and msg.delay to 0 then passing the msg.payload through but his doesn't…

Not ideal but I have added a button that injects a Msg.reset = true to the delay mode so I can reset it and the set the new wait time. Thanks for your help everyone

I found this thread as I wanted the same functionality. I slightly tweaked the code, but result is the same: [image] This flow functions and an inject node, but allows the interval to be changed. The basic principle that the delay node output if fed back to itself through a change node which set…

The inject node cannot be programmatically set, but you can do what you want in another way - check out Colin's neat solution or the sophisticated node-red-contrib-msg-resend node.
