Sensor values are static until page is reloaded

[pman100]

Hi. I tried the new helper function grouping with sensors sum and together with the group-card. The intention with this is to avoid have updating the sensor two times, first to list all the sensor and the get a summery of the total value. It works fine except for one thing. The sensor values from the group-card stay static and is only updated when the page is reloaded. My yaml code is this:

type: entities title: 'Power heat and water ' entities:

• type: custom:group-card card: type: entities group: sensor.power_heat_and_water
• type: custom:text-divider-row text: Total power
• entity: sensor.power_heat_and_water name: Power heat and water

is this something that can be updated in the future. Thank for your help. Peter
