Ok, Here is what I have been thinking of:
a PI, many sensors and controls.
the pi to do the things the pi always does.
the sensors to sense room temp. in each room.
And this is the hardest one, flow control per radiator.
I want that I can set room temp schedules, and can go off schedule using the app (manual intervention)
When the current temp in any room is below the set temp for that room the heater system turns on
The rooms that are already above their set temp have the radiators turned down.
Why? Because I don't like to waste heat to a room I don't enter 90% of the day.
And when my living room has reached the target temp there is always a room that is either still stone cold or feels like sauna.
The hardest part about this is the controllable radiator valves, the rest already exists.
- deepsy 10y agoActually, this is on top on my to-do list. I've been thinking about it for some time. Currently I'm planning to do it via motor and a reductor with ~1:1000 rate. The other issue is to find a cheap way to connect all radiators without putting cables everywhere. I'm open for suggestions :)
- Freestyler_3 10y agoData can go over the air, the power either has to be battery or cable. The other commenter has a link to a product that works on battery. (though that has the temp sensor inside the device, which I don't consider reliable, being so close to the heat source) It would be an amazing project when redoing a house, as at that point I could just run a special circuit. So yeah check out that link, for your convenience copied here: http://www.vesternet.com/smart-home/technologies/z-wave/heating-cooling/radiator-valves http://www.vesternet.com/smart-home/technologies/z-wave/heat...
- bloaf 10y agoI have a lot of similar ideas. The one constant problem I keep running into is the amount of work it would be to get power to all those devices. I'd absolutely love if it were possible to power + network all the devices via PoE, but those adapters are so expensive. If anyone knows of a good Pi-like board that runs off PoE out of the box, let me know.
- Freestyler_3 10y agoYeah you always need some cables if you don't want to change batteries all the time, and wifi is convenient but its better to use wired. I think there are 2 options, 1 you run everything on the network. 2 you use PI's io to directly control/sense. The power either comes from pi, poe or a separate adapter (either at pi running with other wires or near radiator)
- lucaspiller 10y agoFor radiator valves look into actuators like this, there are a few different manufacturers: http://www.vesternet.com/smart-home/technologies/z-wave/heating-cooling/radiator-valves http://www.vesternet.com/smart-home/technologies/z-wave/heat...
