Outside compensation curve

[Erwin van der Zwart]

For the outdoor temp combined with a curve i usually use a 3 days average, this can simply be done by attaching a trend to your measurement object and use this small script.

Code:

require('trends')
dateslastthreedays = {}
dateslastthreedays['start'] = os.date('*t', os.time() - (86400 * 4))
dateslastthreedays['end'] = os.date('*t', os.time() - (86400 * 1))
threedaysaverage = trends.fetchone('OUTDOOR TEMP', dateslastthreedays)
