Card is blank

[wabbastang]

I thought I was having the same issue, blank card. I also was trying to use card-mod but it wouldn't work, would throw an error ("i.setConfig not valid" or something long those lines), so I removed that and stripped out the style section. At that point the error messages stopped but it appeared to be showing a blank card. However it occurred to me it might just not be visible, so highlighted the card dragging the cursor down from "route to" and sure enough, there was my travel times, white on white. So for me it is a formatting issue, not the waze card itself.

hi, probably it is a colors issue.
Try to use the following configuration:

type: custom:mod-card
card:
	type: 'custom:ha-card-waze-travel-time'
	header: false
	name: Route to...
	unit: mi
	columns:
	  - from
	  - to
	  - duration
	  - distance
	  - icon
	destinations:
	  - entity: sensor.to_work
	    from: Home
	    to: Work
	  - entity: sensor.to_home
	    to: Home
style: |
  ha-card {
    --primary-text-color: #FFFFFF;
    --secondary-text-color: #727272;
    --text-primary-color: #ffffff;
    --disabled-text-color: #bdbdbd;
    background-image: url("/local/imgs/card_back.png")
    background-repeat: no-repeat
    background-color: rgba(50,50,50,0.3)
    background-size: 100% 300px
    border-radius: 20px
    border: solid 1px rgba(100,100,100,0.3)
    box-shadow: 3px 3px rgba(0,0,0,0.4)
  } 

You can change the card colors as you like.
Thanks, Renato
