Hey guys, is there any easy/cheap way to track power usage based on appliance/room that doesn't involve some draconian self reported logging?

@Ruki will know how! I recall he was discussing some Pi setups for this.

You can get plug in meters for individual devices.

 

You can get switchboard meters that record on a per circuit basis (where 1 breaker = 1 circuit).  But you are unlikely to have separate power and light circuits for each room.

It's likely the heat pump is on it's own circuit.

 

But it's likely there is more than one room per power point circuit so attributing power use to individual flatmates rooms could be difficult.

 

Trouble in the flat on the subject of power consumption?

Not yet, but power bill has gone from $50 a week to $170 a week, so want to head it off before people actually complain. I know one flatmate has bought a oil coloum heater, but I don't want to single them out.

Which power company are you with? As if it is Flick electric your high bills will probably be to do with the high wholesale prices right now. (I don't know of any other power companies that do weekly billing)

 

And definitely stick a plug in meter on any heaters. As you will get arguments if you have some flatmates who like to be toasty warm, while others prefer to freeze and have lower bills. As there are people out there who don't understand that electric heaters use lots of power.

Yeah it's flick, and yeah that's exactly the issue. some people arent using heaters but some are, no arguments yet but its not fair if one person has used 4x more than anyone else.

The oil column heater in our baby's room runs ~12 hours per night.  It's on a thermostat on the lowest temp, and its set to half power (1200w) not full power.  In this setup it is on roughly 50% of the time and costs ~$1.50 per night to run.

 

Extrapolating those numbers if it was on 100% of the time, running at full power and on 24 hrs a day ($1.50 x2 x2 x2) it could cost $12/day.

Have you been following the spot prices lately? As during peak usage times they are often complete bonkers right now due to low water levels in the main Hydro lakes. I think a rule of no electric heaters should be implemented. At least until the hydro lakes fill up some more.

~difficult~ flatmates could simply unplug heater from the power meter & plug it in somewhere else , then leave it running 24/7

 

Perhaps look at temps in individual rooms at various times of the day , see what heaters have a thermostat & what temp its set to
Then start timing showers & baths (hot water use) , its a slippery slope if you want to do all this properly :-)
Dont disregard the cost of hot water heating

Ah haa this is my argument that new homes should be required to have solar assisted electricity and water. 

 

Not purely for the cost savings, not because it reduces load on lines, but simply to keep the lake levels higher. Less line consumption during the day means the lake levels can stay higher for longer. And it encourages homeowners to consume their power during the day (time delay appliances) so that they dont need to draw as much from the grid at night.

I don't miss those discussions.  It can get difficult fast.  The only way through I found is to try to agree what is reasonable power usage and everyone stick to it.  Has to be done in an way that doesn't make anyone feel ganged up on.

 

Some people do feel the cold more, so use their heaters more. 

 

Some people have gaming computers with triple monitors and grunty power supplies.

 

Some people have more and longer showers.

 

Best of luck.

This makes no difference. It just means it's on twice as long at half the power for the same amount of heating.
