There appears to be security issues with a lot of these IoT devices. But you didn't ask that question. You asked is it worth it? That I can't answer but if you have check if the garage door is closed and have no one at home to check it, maybe 150 bucks is worth it.
That said, most home alarm systems are now Internet connected and adding the garage door status might be an option.
I saw an ad on Facebook and am trying to determine whether or not to purchase this product called Garager 2, it is a two in one device (garage camera and remote controller two in one) Seems to match my needs as I do tend to forget my garage status.
Right now the price is $149.99. I am debating internally on whether or not to make the decision.
Thoughts on this everyone?
