- I saw a post recently about a smart thermostat. It didn't sound smart
- enough for me. It seems to me that a smart thermostat would be one that
- "knew" what the heat requirements are likely to be. The only smarts I have
- seen in thermostats is the anticipator, which cuts the heat off BEFORE the
- thermostat proper indicates the set temp has been reached. What I think _I_
- need is a thermostat that cuts the heat ON BEFORE the thermostat calls for
- heat. Why -- big masonry house in very cold climate with steam heat. The
- regular Honeywell thermostats I have result in way too much hysteresis,
- because by the time the temp has dropped enough to trigger the thermostat, it
- will continue to drop while steam comes up. Do they make _really_ smart home
- thermostats, that, for example, have a clue as to what the OUTSIDE
- temperature is so they can determine the make-up heat needed and supply it
- in a genuinely timely fashion and not when some bimetallic strip says "its
- too cold in here!". Seems reasonable to ask that a heating system keep the
- right temp, not oscillate between too hot and too cold....
