The microwave would not function if the time and AM/PM values were not set. (As far as I could tell, there was no way to actually ever see the AM/PM value after setting it!)
So. Every time the power went out, I would be confronted with blinking times on clocks I didn’t even want, and a nonfunctional microwave.
I will never buy a kitchen appliance with a mandatory clock ever again.
I fired off an E-mail to Siemens, stating that there was ONE feature which could tempt me into granting it access: NTP support.
Much to my surprise, I got an enthusiastic reply from an engineer stating that this would be rolled out in a future firmware update.
Fingers crossed.
I hadn't thought of that. I'll add that to my list of reasons why I will not buy an appliance that wants to connect to a network.
