Create new dashboard section from API

Hi

I’ve got HA up and running and have some items on the dashboard for my tado thermostat and Wiz lights etc but would like to add something via the tado API.

Using the http URL I can view the current flow temp of my boiler

https://my.tado.com/api/v2/homeByBridge/IBxxxxxx/boilerWiringInstallationState?authKey=xxxx

This returns the following:

{“state”:“INSTALLATION_COMPLETED”,“deviceWiredToBoiler”:{“type”:“BU01”,“serialNo”:“BUxxxxxxx”,“thermInterfaceType”:“HT_BUS”,“connected”:true,“lastRequestTimestamp”:“2025-02-09T10:05:52.266Z”},“bridgeConnected”:true,“hotWaterZonePresent”:false,“boiler”:{“outputTemperature”:{“celsius”:42.5,“timestamp”:“2025-02-09T10:12:04.000Z”}}}

Is it possible to create a dashboard item where it queries the URL every 5 mins to get the flow temp and just display the “celsius”:42.5 element of it?
