Hi Simon,
Thank you very much for sharing this undocumented command. It really works!
As far as NTP is concerned, NTP does not recognize time zones. Looking at the timestamps, I can tell that smart ovens and fridges already have the current UTC time. I’m assuming the problem with displaying the time is the time zone (Determining the time zone from a network IP address may not be accurate and they don’t want it to be a service call generator.)
Thank you for sharing possible issues with implementing clock automation. I was going to update the clock every day. But now I think that I will do it once in a while. I couldn’t find an easy way to tell if the oven clock is out of sync. I’ll probably update the time with a home automation voice command. Power outages don’t happen often and this should work for me well.
By the way, are there any other configuration commands? For example, it would be nice to be able to override the default oven setting of 350 degrees because in 99% of times we use 375 degrees for baking.
