Individual room temperature setting and heating
Posted: Tue May 26, 2015 9:49 pm
I would like to share to you my solution to set and control the temperature for every individual room in my house.
Hardware:
- ELV MAX! cube and thermo radiator controls
- RFXCOm RFXtrx433
- Heatmiser WiFi thermostat
- Olimex A20
(And a heater of cource)
Software:
- Debian linux for the A20
- OpenHAB
The solution is a setup where the temperature per room can be set by hand or through the openHAB interface in a browser or smart phone. The radiator controls reveal their status by showing how far they are open. When open for more then 25% I assume there is (al least somewhere in the house) the need for heating. I then send a command to the Heatmiser to turn the heater on. And reversely when there is no valve open for more than 25%.
This is off course the brief version of my setup. In reality I also use a virtual thermostat for the living room that can be programmed. If you like I can tell you more, bat the principle is above. Cost of all this?
- ELV Max Cube 50
- Radiator control 35x number needed, in my case 7 = 245
- RfxCOM 110
- Heatmiser 150 (in my case the PRT-ts WiFi)
- Olimex A20 120
The software is open source, so a total of around 550 euro. And the system is competed suited for other domotica setups as well.
Happy to share more details if you like.
