HOT_WATER -> OFF

[fgrosswig]

is there an option to set HOT_WATER to 0 while toggled off? i played with the temp lowering down to 30 degrees which works but usually the WATER system can be set to OFF during a timeframe at night. Would be interessting to see the "OFF" valve in the chart as well.

Would also like this for room temperatures. At present, it looks like the tado API just returns a "null" value along with an additional power: "OFF", attribute.
