- call compute value direct, enlarge TCP stack [#3127](https://github.com/emsesp/EMS-ESP32/discussions/3127)
- Dewtemperature for Easycontrol calculated by ems-esp [3135](https://github.com/emsesp/EMS-ESP32/issues/3135)
- add option for sync thermostat to ntp, allow different time zones [3148](https://github.com/emsesp/EMS-ESP32/discussions/3148), defaults to no sync.
