You should be able to do all of that, assuming you haven't already figured it out, here's how:
Ok, I lied... it probably is possible to do this, but I haven't played around with ITTT or the API enough to help tell you how you'd do it. If you figure this out it'd be cool to hear how you did it. Alternatively what you could do is set the garage door to alert you anytime the door has been open longer than a period of time. I assume you don't want to leave your garage door open for long periods of time anyways. That'd maybe work for you?
Via the web interface (couldn't find it in the iOS app, but maybe it's there too) in the ARM / DISARM menu there's a 3rd menu option called "Options..." In here you can define 2 schedules for auto arming and disarming. I used to use this feature when I had a more regular schedule and it worked great.
I've set my tags "Receiver Mode" to use the Low Power Mode and get anywhere from 1 to 2 years of battery life. I set polling/logging anywhere from 1 minute to 5 minute intervals. I think I set most of my tags to medium for the sampling. I've purchased these batteries on Amazon: https://www.amazon.com/gp/product/B008XBK7PG/ and also some cheap IKEA ones and they seem to work fine. I should probably do some head-to-head comparison between them but frankly it's not been a big deal for me. When one battery goes low I just replace most of them so I don't have to think about it again for another year. If you are handy with a soldering iron and don't care about the size of the tag you can solder on a AAA battery pack. I did that to an older tag of mine and it's worked out great - otherwise the Motion & Reed sensors use a larger CR2450 battery that seems to last a few years at a time. Again it hasn't been such a big deal for me, but I can see how depending on the location it might be a pain to replace batteries. :)
How do you define expensive?I purchased this and with really heavy use throughout the year I've only gone through 2 batteries. That's less than $2 for a full years worth of batteries.
They are so cheap that whenever I find a friend who owns a go plus, I just give them 2 batteries. 2 batteries should last a year for 95% of people and cost pennies.
Sounds like a battery issue. I usually keep a few extra in the grip of my rifle for when they start to go dim. They use the CR2032. I usually buy those in bulk because I have several scopes and red dots that use that same battery.
I bought these last year. They seem quite legit, good power output, and still running in the devices I put them in last year.
It's a CR2032 battery, and you'll need one of these drivers. You could probably get a friend to do it or go to a local PC repair or circuit board repair shop and get it done for next to nothing.
I had to do some convincing to get him to tap it with a soldering iron, since it's a battery, but someone at a local shop did mine for me for free.
