mum or wife
btw, Bill, your site became sloooooow (used to be fast, now pictures open very slowly) ...
bin thinking last night about this .. I noticed that Bill mentioned few HVAC standards (I do not know any of them) but making the device follow them (being able to join the network with other HVAC devices.. communicate with them ..) would be very interesting
I still believe sw part of the project will be a *****.
The IO part: [easy]
- detect all sensors (1wire, i2c, rf, ir) - almost easy
- get data from all sensors - easy
- turn relay's on/off (on board or via i2c port extender) - easy
- serial comm - easy
- ir comm - easy
- log data to i2c eeprom - easy
- read button & rotary encoder - easy
- RTC - easy
The logic part: [tough]
- dynamic menu system [mid tough]
* allow user to control every single sensor
* allow user to set weight for every single sensor
* allow user to go trough log
* full scheduler setup
* RTC control (set time)
- data display [easy]
- data analysis and element controll [tough]
The network part: [I have no idea]
- HVAC standard??
The network part can be "left for kit builder to develop as extension" .. but rest of it have to come with the kit .. and .. it's not easy, the data analysis need to be full dynamic control, not just simple hysteresis on/off switch - and when multiple differently weighted sensors come to story, it gets interesting
