when the broker restarts it seems possible that retained messages are lost. We should republish config periodically (not on reconnects since it could be due to a bad connection)

Add possibility to persist config settings across reboots. Its mostly about values changed while running.

There should also be the possibility to reset the config to default values (aka values set in settings.h) via MQTT.

To reduce mouldy smell ventilation should be turned on approximately every 24hours even if humidity would not be reduced. Still it should only run if dew point delta is <=0.

Idea:

• remember last ventilation run (turn off time)
• if (hum >80 && last run >24h) mindelta =0 until vent ran for 1 hour.

To consider

• save on/off time
• reset other timer when saving
• set mindelta to 0 before evaluating other rules so that normal rules apply. => or even negative to force it to run.
• condition: if (hum > x & & (off >24h || on <1h)
• introduce locally scoped tmp_mindelta to keep original value - check logs and outputs for required adaptions
• add new mode AUTO-ON to keep track of this state and measure time properly

It seems that when the heater is on, sensor cannot be read, thus leading to a reboot. Error checking should be turned off while heater is on.
