Both through app and IFTTT, it seems as though my ignition notification doesn't come through for about 1-2 minutes. Although decent, it does lead a lot to be desired for trying to utilize for remote start for winter days (whether or not it started if no line of sight). My guess is because it is syncing with the site first, then pushing to devices. I'd think that if something along the lines of the device itself can send out a quick push to Pushover direct on ignition (or just allow for us to make a POST web request), it may significantly decrease the time to notification.
Either way, loving the device so far. Got this hooked to my garage with geofencing in IFTTT, and it's almost like magic now coming home to an already opened garage (As most geofencing attempts with phone we're not accurate enough to reliably open the garage due to battery saving measures by phone.)
