I like the thermostat and app but it has flaws: With True Radiant set to 1 hour max (and both Auto-Schedule and Eco modes Off) it can turn on the heating much earlier instead of only coming on if/when it needs to to get the temperature to the set level by the set time. Sometimes it doesn't come on early at all. Unreliable! The usage history graph is next to pointless, running according to its own odd timezone and not showing a lot. See the Heatmiser app for how it should be done. The web version scheduler shows most settings 0.5 degrees out from what the app does so is unusable for quickly setting things up.
