This is less about R083 than the 'cloud'.
I decided to do some testing before upgrading from R080 to R083, WeMo lamps, Aeon Labs appliance switch.
On the Web UI, the Sensors page, the lamp slider control now functions as you would expect. No lockups, only a little sluggish, however the x% displayed is incorrect (one say 0%, another says 100%, another says 21%, and none change value when the sliders/lights change level). The sliders remain at the last command level.
So it appears they've improved the 'cloud' functioning as well.
The 5.0 Android App x% display is similarly 'stuck', but the sliders function well to set the levels. After some seconds of inactivity, the sliders return to the x% value, yet the light doesn't change. So assuming this operates correctly on R083, the cloud and App fixes were not all that was necessary to get these to interplay/react properly.
The app and the WebUI get out of sync on the appliance switch, showing OFF when on, although at one point they were updating as it was switched, and presently shows OFF *and* 36.687 watts. If I change the 'load' power, then on the next power cycle of the appliance switch, then the power value updates. Now showing OFF *and* 34.822W. Let's hope R083 improves this.
No Rules tab content yet on the 5.0 App.
I'm also hoping the wired LAN dropouts, the wifi devices reconnecting to almond+, and the required 'wakeup' push on the keyfobs all go away, too. Oh, and maybe I'll be able to get rid of the CRON entry to reboot daily.
Updated to R083.
Set lamp power level to 52% via the LCD. Reads 51% and OFF on the 5.0App. Hit slider to 92, shows 92% and OFF, on the App.
Another Lamp shows ON and 0%, it's on near fully on.
