Dear All, I would like to have a functionality where in I need to run specific flow repeatedly when I receive specific type of message. Please let me know how to handle this in node red. Is it possible to do this in trigger node. If so please let me know how to do this? Thanks & Regards Varun

Hi, Thanks for the response. But how to input specific message to inject node? Thanks & Regards Varun

You don't you remove inject and feed your message into the switch node. The injects where to show what happens with different message values.

Post you code between back ticks to make it easy to copy and paste. e.g. ``` code ``` becomes code

edit previous by clicking pencil icon, then add back ticks before and after code, on their own line. [image] Newbies forum/section? General For real newbies… How to interact with the forum for nulls like me. blush how to put an image in a post… Simply use the upload icon and drag the file. Or copy the image in the clipboard and paste it in the post. blush How to share code in the forum, a node-red node should be selected first, otherwise the Export menu item may be disabled. and then use Export->Clipboard. [image] Then Select, for example, “Current Flow and compact”. And Export to clipboard . [image] Go to your post,…

Hope now your able to copy the code. I wanted to have complete control over variable delay node in my code. That is I want to trigger or stop sending message to subsequent flow based on specific message.

Yes to copy flow i can now click copy icon, also no messy code all over thread, maybe you could tidy up the mess? As to what you are attempting, more info is required as i am not getting it.

Ok Sorry for the messy code. I was trying lot of options.Let me tell my requirement. Requirement: At specific time inject node will trigger to turn OFF water dispensing system. after 10mins I shall turn it on again the water dispensing system. Step 1 and 2 should repeat till specific time is reached after that it stop looping till next day, This what I wanted to achieve. I tried using trigger node. Which helps to loop but I was not have any control to stop it after specific time is reached.

so how do you turn it on? what device?
