Schedule() runs but is not sending commands to device

A scheduled method in a SmartApp doesn’t require hubaction to send commands to the device, but it is required for scheduled methods in a device handler. The ability to run schedules from within a device handler is relatively new so I’m pretty sure it’s always been required.

I wrote a device handler middle of last year that used schedule(), and at the time it worked, without needing to use sendHubCommand(). However, it broke at some point, which is why I’m re-visiting it now.

The “updated” method is executed twice when tapping done from the device’s settings screen which can cause problems if you’re sending a lot of commands to the device from that method. I’m not sure if this happens with iOS, but it’s been doing this on Android for over a year.

Yep, got that covered here: Updated() being called twice?

I really wish these kind of things were better-documented!
