Newly added ESPHome temperature sensor has no history until a restart

Hi,

I’ve recently started using ESPHome to monitor my Panasonic air conditioner using this: GitHub - DomiStyle/esphome-panasonic-ac: Open source alternative for Panasonic air condition wifi adapters that works locally without the cloud

With this I get an outside temperature sensor but it wasn’t keeping any history until I restarted Home Assistant.

Is that expected?
