WebControl by CAI Networks is a $35 TCP/IP-based (web) device that I've used for about a year and can recommend.
Provides eight digital (TTL) in, eight TTL out, three general purpose 0-10vdc analog in, eight 1-wire temperature inputs, and a dedicated HIH-xxx humidity sensor input.
One can create rules using Boolean AND/OR logic with the various inputs including TTL-level logic, 0-10vdc analog, temperature, Relative Humidity, and Date+Time and delay timers to control the TTL outputs.
The built-in Real Time clock (RTC) can be kept accurate by Network Time Protocol (NTP).
Supports email notification upon state change.
The WebControl PCB has circuitry for RS-232 and RS-485 I/O that is not populated with ICs and are still unsupported by the firmware. I had a useful conversation with the manufacturer about the potential to support BACnet. They are up against memory constraints in the microcontroller.
I also tested various 1-wire temperature devices for them and based on that they added the more accurate DS18B20 1-wire device than the "econo" DS1822 device which was the only device they previously supported.

Find available suppliers through Amazon.com:
http://www.amazon.com/Webcontrol-Universal...7812&sr=1-1
Also eBay (currently more expensive. but may include the case which is steel, compact and of good quality)
IMO, quite the bargain at $34.99 + $4.49 shipping to US = $39.48 delivered.
