Description
A programmable thermostat is required to keep costs down while keeping everyone as happy as possible with the temperature of the shop.
Requirements
The programmable thermostat should:
- Be remote controllable (all features)
- Wifi, indirect network connection such as serial to a laptop, xbee
- Be able to control a heating device via 120V relay
- 1 GPIO
- Be able to control a cooling device via 120V relay
- 1 GPIO
- Be able to control a heating or cooling device by remote means
- Currently, X10 and X10 via network proxy are options
- Have a user interface for people to interact with at the physical location
- LCD with buttons
- Be able to monitor temperature accurately in one or more locations
- DS18B20+ temp sensors
- USB temperature sensor?
- Built-in temp sensor?
- Have certain software capabilities
- Hot target with hot-side hysteresis
- Cold target with cold-side hysteresis
- Relaxable hysteresis based on timeout with audible warning of relaxation
- Relaxation cancellation capability (local or remote user can silence alarm and reset timeout)
