Progress humidity alarms

It is winter time again and I am leaving soon for two weeks. Who will take care of reminding people to open the windows in that time?

The Annoying Humidity Alarm (TM) :-)

Tasks:

• Write Hausbus node software to approximate wall temperature and calculate the dew point of the indoor air.
• Ideally, wall temperature is approximated using a 12-24 hour average of indoor and outside temperature
• Find a working, not annoying way of notification: E.g. a short alarm at first, getting more and more annoying over time. Ideally, taking night time into account with a reduced volume
• Extend the system to get "centralized" alarm (e.g. find a way to alarm people of too high humidity in a room nobody is in)

Consideration of done for Winter Roadmap:

• Kitchen humidity alarm works using wall temperature approximation (without average temperatures) and short melody alarm
