According to reliable reports, several Google Home users are not able to control their smart lights using Assistant voice commands. The problem has been in existence for well over a few weeks now. The problem came to light when Reddit user u/usernamechecquesout shared a post on the google home subreddit stating that “Google home stopped understanding light control commands this week”. Redditors commented on the post stating that the problem is indeed not limited to the OP. Due to this problem the Home devices are replaying “I don’t understand” to a lot of light commands. Common solutions like rebooting the Google Home device or reverting to factory settings didn’t help fix the problem. As of now, Google hasn’t issued an official public statement. However, according to people who have contacted support, Google is very well aware of the existence of this problem and is investigating it. UPDATE At the time of writing this article, the problem has been completely fixed. A Google spokesperson told Xda-developers that, “We’re aware that there was an issue impacting Assistant powered devices. It has been fixed and Assistant is working as it previously did.” So if you were facing the aforementioned problem simply try giving new commands and Google Home will work as it used to.
