Opal Ice Nugget Review

I like the features and UI of the app, but as others have mentioned the schedule I set for ice machine keeps turning off. I set the days and enable the schedule, and then when I come back the next day to check why the machine didn’t turn on as scheduled, I notice the schedule is disabled. This problem seems to happen every other day. Fix your buggy software!!!

This app is a total waste. I have never been able to use the scheduler. I’ve set it but it never turns on. I’ll go back to check my schedule & it’s turned off when I know I had it on. Also, what’s the point of having an app if I can only use it to turn on my machine at home? It needs to be WiFi enabled, not Bluetooth. I can’t tell you how many times I’ve been away from home & need to turn it on but can’t because the app won’t connect unless it’s in the vicinity of the ice maker. The schedule needs to be changed also. Like the alarm apps that have a spinning selection of date & time so you can set it specifically to turn on at a certain time or turn off at a specific time. For the price I paid for a ice maker, you’d think the technology for an app would be much more sophisticated. Needs a complete overhaul to be used to its ability. The last thing is I don’t want to be forced into seeing all of the other FirstBuild products when opening the app. I want to connect to my device and operate it. I shouldn’t have to wait each and every time for the machine to connect to the app, it should be set up initially but after that, remain connected.

Tip for enabling schedule

For all the people complaining that the schedule feature doesn’t work, try leaving your ice maker powered ON. Never turn the unit off with the power button. If anyone in your household presses the power button on the unit, that will turn off not only the machine but will also disable the schedule. Once someone turns the Opal off using the power button, the machine cannot power itself back on without a human touching the physical button — even if you have scheduled it to make ice for a future day / time. The unit CAN stop making ice and return to making ice on schedule as long as nobody touches the power button. I hope that makes sense and helps people. Other than that, the app is annoying for all the other reasons people have mentioned. Great ice maker, lame app.
