I’m a big fan of .SVGs too, I might also convert my dashboards. Which editor are you using; Inkscape?
I’ve found this to be a great site for creating animated SVGs if you’re interested in that.
The HTTP Response node just returns an acknowledgement to the sender (Motioneye) to keep it from retrying, logging errors, etc. No configuration is needed in NR, you just attach it to the flow and it automatically responds.
There’s probably some way to send only values without keys via POST but I guess it’s not as simple as I was assuming. Oh well, it turns out to not be helpful in this case anyway.
Glad everything’s working!
