I need to create a button in HA which directs me to a site with dynamic IP address. This template is created in configuration.yaml and gives me the IP (part og the URL needed).
I have tried different versions of this without success: url_path: < http://{{ sensor.ext_ip }}:9123
Any tip on how to create a dynamic URL for a push button (tap_action: / action: url / url_path:) where the dynamic IP is a part of the address and the rest is static?
