* Add ema calculation class, calculate an emo temperature, use the ema_temperature in auto_window dectection * Removes circular dependency error * Fix ema_temp unknown and remove slope smoothing * 15 sec between two slope calculation * Take Maia feedbacks on the algo. * Maia comments: change MAX_ALPHA to 0.5, add slope calculation at each cycle. * With EMA entity and slope calculation optimisations * Change open_window_detection fake datapoint threshold * Try auto window new algo * Don't store datetime of fake datapoint * Change auto window threshold in °/hour --------- Co-authored-by: Jean-Marc Collin <jean-marc.collin-extern@renault.com>
