I was wondering if there was a way to render a fallback image for a dashboard. Basically, my use case is that I’d like to display an image of the sensor provided by the customer. If no image exists, then I’d display a “No Image Available” image (as opposed to a block render error).
One idea I had was to add a tag to the devices that specified the path to the image. I could then set this
imagePath to the fallback image if none other existed. However, I don’t think I can use a context variable to pass this down as the user would have to pass the path in – ideally I just want to use the value of this tag depending on the image selected. Any thoughts? Thanks!
