Do Google Home speakers reboot every night?

Configuration
1

Every night I get these errors in HA

[xxx.xxx.x.18:8009] Heartbeat timeout, resetting connection
Timeout contacting http://xxx.xxx.x.18:8008/setup/assistant/alarms
ClientError contacting http://xxx.xxx.x.18:8008/setup/assistant/alarms - Cannot connect to host xxx.xxx.x..18:8008 ssl:None [Connection refused]

The same logs I get when I unplug Google Home. Is Google Home rebooting every night? I’ve seen posts on reddit where people claimed that their devices usually reboot in the night to check for updates.

I’m using Hassio 0.93.2, Google Home alarm sensor component and I also have one Chromecast at home.

I’ve experienced this too in the past but not checked my logs recently I have to admit…
