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.
Alternative Firmware[Bearbeiten]
We are currently writing an alternative Firmware for one one of these revisions. You can get it by cloning this git repository:
git clone http://www.0x53a.de/git/sparmatic
(This repo might not have the latest state...)
Features[Bearbeiten]
- 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[Bearbeiten]
- 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)
