Problems with a template not providing expected results in Lovelace card

Configuration Frontend
1

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.

This is how I want the results to end up

tap_action:
  action: url
  url_path: 'http://172.16.0.176'

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.

{{ "http://"~state_attr('sensor.tuyad7_status', 'IPAddress')}}

{{'http://'}}{{state_attr('sensor.tuyad7_status', 'IPAddress')}}

http://{{ state_attr('sensor.tuyad7_status', 'IPAddress') }}

Any ideas ?

It’s likely that you can’t use templates there. There is certainly no mention of it in the documentation.

Hey, did you find a solution?

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

## lovelace code

hold_action:
  action: call-service

    text: tuyad5 restart ?

    var mq = states['sensor.tuyad5_status'].attributes.MqttCount;
    return 'mqtt: ' + (mq ? mq : '0') ;
  ]]]

              if (states['sensor.tuyad5_status'].attributes.MqttCount < Math.round(states['input_number.mqtt_threshold'].state) ) return 'green';
              else return 'red';
            ]]]
          opacity: 0.5
