Just before I started with my DreamQuest project I was working on a project called HomeTerm. HomeTerm is a web-enabled thermostat. The idea is that you have your HomeTerm device at home controlling the temperature just like a normal thermostat but with the added bennefits of the Internet.
You can control and monitor the temperature of your room from almost anywhere. You can enter a detailed temperature plan from the comfort of your computer. Also detailed graphs are available for temperature and humidity.
I have a Meridan/P from Device Solutions but never given it a propper introduction. The Meridan/P has the same connections and powerfull functions as it’s bigger brother the Tahoe II but in a smaller package (50mm x 50mm). It lacks the screen and the ethernet connection but both can be added externaly should be needed. The pinout of the connectors match up with the connectors on the Tahoe II so converting your project to this new board is easy!
I use the Meridan/P in my HomeTerm project now as external temperature sensor. The baseboard (Tahoe II) is connected to the Meridan/P with Xbee. The Meridan/P also controls an RGB LED matrix allowing you to put the temperature sensor in sight. The baseboard sends the current time and external temperature from Yahoo Weather to the Meridan/P and in response to that it sends the current room temperature back.
