When the weather is mild (-5C to 5-10C), my heat pump has a really hard time recovering from the lower temperatures set during the night and even has a hard time keeping up during the day. I’m not sure how much control the Ecobee has over this (might be defrost related? although I don’t see any ice on the heat exchanger) and it might be purely on the heat pump side. Is there something wrong here? The heat pump is able to keep up just fine without aux when it’s -25C outside.
