Beeing alarmed

A user mailed last week and wanted his car warmer to start in the morning if the temperature was below a certain level and asked if there was no Item that could act on temperature levels (like a thermostat). This seemed like such an obvious function so I actually had to check if it was not already there – and it was not! So now I have made the new HomeItem “ValueTrigger”. You specify an attribute in another Item (a thermometer for example) and specify a max and a min level, together with actions to be performed if the value goes above max or below min. There are also separate methods which are called once a minute as long as the value is above max or below min. The Item has enable and disable actions so you can use a timer to only activate it during specific time periods.This is now in the nightly build.
