I think the sensor beeps non-stop if/when it disconnects from Bluetooth. At least that's the impression I got from the FAQs.
Did they address what happens if the battery dies over night (especially in winter temps) and you don't realize it and your phone is in your purse so you don't notice it didn't connect? Okay, I just went and read their FAQ and they don't seem to address this.
I saw this too (none of this directed at AllieK, just random comments from me
):
Should the connection drop between your phone and the monitor, you will receive an alert to notify you of this. Note the app should automatically attempt to reconnect.
I hope they designed this alert to be able to be a different sound than the other alerts, and that it also sounds again on reconnection (and a slightly different sound like one beep for disconnect, 2 for reconnect). Because I sure as heck would be PO'ed if it was the same as every other alert sound and I pulled over thinking my kid had climbed out of their seat and I find that the alert said the app disconnected but had already reconnected while I was pulling over.
And this one:
Child left in seat alert:
Based on the reminder interval set in your Driver's Little Helper app you will be alerted after this time should your child still be left in the seat and the car is no longer moving.
Since typically people aren't sitting in the car when they forget their kid in the car, I don't quite get the purpose of this one. I am sick today so I may just be dense.
What if you get home, kid is sleeping, so you run into the house to grab something for the next errand while kid is sleeping in vehicle, it alerts you it disconnected from bluetooth but you knew it would since you were going into the house so you ignore that alert, then the house phone rings and you start chatting with someone...and forget your kid in the car on the driveway or in the garage.
And the above scenario is not far fetched in my world at all. I often get home on Friday evenings and my youngest is sleeping in her seat, I pull into the garage, shut vehicle off and run in and grab the key for the mail, then drive to the mailbox with her, or I pick up something we need to return or whatever as next stop is picking up DH and we'll typically run an errand.
I should probably download the app and see what settings are available and such or check if they have a more thorough user manual than just their FAQ.
