Yeelight ceiling lamp and Siri voice control

Hi. I’m setup a Home assistant on QNAP docker. There’re 2 yeelight ceiling lamp added to the HA. And I using Siri voice control to control these lamp. I will disable the wifi and shutdown the QNAP for server hours and then restart it in the morning. I found that these devices will stop respond to Siri and HA. I need to power reset these lamps in order to take control again.
Also I can only use Siri to turn on or off and change brightness of the lamp. How can I change the color temperature with Siri?
Another problem is I can add a Sony Bravia TV into HA and only can control its power status through Siri. I cannot control the volume, channel etc through Siri.
