I am trying to use a template in button card but not getting the expected results. I think it is because the the result of the template is not a proper string.
Except that I want the url entry to come from a template. These are the three versions I have tried in the developer template tool and they all seem to work fine there, but not as the url_path in button card.
Sort of. My issue was running Ha in rpi3b and it was getting tight on memory, so I wanted to off load Tasmota Admin and make my own basic dashboard to monitor Tasmota devices. ( swap file was being used a lot) I ended up with using info button. After you click info, double click displayed ip address to select it, and right click to open in browser. A bit convoluted but didn’t use this feature too often. More used / needed was a way to restart mqtt device. I then used a long press to do mqtt restart. Not sure if this will help you, but here’s my card code, and sensor_mq_cnt_yaml
