I often get a “Charging limited by temperature” message on summer days. It’s great that the unit has this protection, but as a future feature, it would be good if there was a relay inside the unit that would through software configuration be set to “close” when the temperature reaches a point that would limit the charging rate. This relay function would be off by default so would not effect anyone not using it.
This is not to provide power, just close a 12v relay. 12v relays can handle decent loads, and this could be used to either switch the power to a small computer style fan for either direct airflow, or for area exhaust, or as a signal for a smart home.
