**UPDATE: they replied to me early this morning that they were working on it, and it is back up today! **
I got errors when I restarted this afternoon. I visited the website wifiaquatimer.com and their SSL Certificate just expired. So I suspect that is why the component is failing.
FYI, I reported the problem via the melor.com contact form. Their tech support has been great in the past so hopefully they can get it resolved soon.
