Sparmatic is a thermostat that is relatively cheap and quite easy to mod. It costs from 13 to 25 EUR. It contains a simple AVR ATmega169/ATmega169PA. However, as there are different microcontrollers mentioned in the last sentence, there are several revisions of the device.

===Features===
* Motor control:
** Readout of the motor's rotation sensor (and counting)
** Current measuring and automatic switch-off
** return to home
** move to specified position
* Readout of the temperature sensor (including some calibration)
* Some simple PI controller
* LCD
** Bargraph
** Day row
** 4 digit numbers (e.g. for temperatures, position counts...)
** All symbols (mostly untested :)
===Planned Features===
* LCD
** Convert characters to 14 segment display (if needed)
* Onewire slave support
* Buttons & Rotary encoder
* Window open switch
* Measurement and inclusion into regulation of return temperature (to get maximum efficiency of the heating)
