This card shows the status of the seven LEDs on the HS-WD200+ dimmer switch connected using zwave_js. The color and blinking of the LEDs are set as configuration parameters of the Z-Wave device and the current zwave_js integration does not reveal them in attributes of a sensor (yet?), so this was kind of a challenge for me.
The code is at: www/homeseer-wd200-status-card.js. (This is my very first Lovelace card, so if I am not doing something in a standard way, I am open to suggestions.)
With a very basic configuration it looks like this:
This is probably too late to help you, but here are some hints for those who may follow.
I wish there were an easy way to explain how to add a custom card. Some of it depends on whether you are configuring Lovelace in YAML or in the dashboard. It would be easy if I restructure my repositories for installation using HACS, which I will probably do one of these days.
Manually:
Create a www subfolder under your config folder if there isn’t one there already.
