2009/08/04 Work on HAI Omnistat code for misterhouse

π 2009-08-04 01:01 in Linux, Linuxha, Public

We recently made a subzone for our bedroom which allows to send a crapload of air from our HVAC system to the bedroom at night so that it can get cooled or heated quickly without bothering to bring the rest of the house to temperature.
But to control and monitor all this, there was some half finished code in misterhouse that I cleaned up, fixed up and improved. I now get reports of what's going on, can remotely control my HVAC system to change its setpoints, remotely and easily program its 48 time and setpoint settings via a web browser instead of the cumbersome panel interface, and of course I can log everything, like so:
