I am calling the camera snapshot service in nodered and specifying the following as Data : { "filename": "/config/www/bedroom{{ now().strftime(\"%Y%m%d-%H%M%S\") }}.jpg" } This works fine if I call the service directly from HA and it creates a file with timestamp but from node red it doesnt take…

var now = new Date(); // Create formatted time var yyyy = now.getFullYear(); var mm = now.getMonth() < 9 ? "0" + (now.getMonth() + 1) : (now.getMonth() + 1); // getMonth() is zero-based var dd = now.getDate() < 10 ? "0" + now.getDate() : now.getDate(); var hh = now.getHours() < 10 ? "0" + now.getHo…

[image] vks007: {{ now().strftime(\"%Y%m%d-%H%M%S\") }} This part of the syntax is python specific, it evaluates the current date time into a yyyy-mm-dd-hhmmss syntax. So you’ll need to replace that part by something that works in JavaScript/Node-RED. The double braces syntax here is specific…

ah! of course, thanks for pointing that out. I'll find a way to do it in javascript.

@afelix Looking around it seems it isnt straight forward to specify a datetime within json , can you give me some pointers please. I could do a new date , format it and return if it was a function but not sure how to do it within a json string

You’re not doing it in a json string. Your doing it in a javascript object. If you format the date as a veritable you can then easily append that using the syntax msg.whatever= “stuff”+variable+”otherstuff”

Thanks @edje11 , I was hoping to put something within the Data field of the call service node but then I can always include a function node before that and pass on the filename as an input to the call service node. Thanks

FYI, here is another thread with a solution that requires no programming... [image] Msg.filename logging data General In the spirit of "there's always another way to do it", I like to use the node-red-contrib-moment node whenever I need to format time and date strings. Her…

This is great but I still have a question. After constructing this file name I need to use the Cal, Service Snapshot node. How do I pass on the path and filename in my filename definition in this node ? So the standard is : { "filename": "/config/www/somefilename.jpg" } How can I modify this an…

@Tokn59 Plese don't post the same thing in multiple threads. I will close this thread since it is over a year old.
