Hi all,
I'm a Canadian user so I have a 3 Wire Edison system - two legs that are each 120V to neutral and 240V leg to leg, I have it set up with two 100A current clamps. Right now I have it set to a single phase install with sensor 1 set to a voltage of 120 and sensor 2 set to a voltage of 120 and I call them L1 and L2, respectively for Line 1 and Line 2. I have a few questions:
1. My actual voltage is around 122/123V per leg, should I change the settings to reflect this? What will give me the most accurate calculation?
2. If I switch it to 3 phase and have it combine the two sensor readings from each 120V leg into a single summed output, what do I put for the voltage? Still 120V or do I put 240? (I don't want to double my actual consumption by accident)
3. If I look at an hourly graph, I have have noticed that I will have a constant consumption and then it will spike over 1000watts for 1 minute, then it returns back the constant consumption value before.
i.e.
6:05pm 1000w
6:06pm 2000w
6:07pm 1000w
What is causing these spikes? Is there anything I can do to prevent them? I know it is not a true load spike.
4. I am using the wifi connection at the moment, if I want to use the wired ethernet connection instead of the wifi, if I hit the toggle button I understand that the ethernet will now get an IP via DHCP, if I toggle back to the wireless, does the flukso revert back to the previous default ethernet settings. i.e. if it was set to default 192.168.255.1/24 while using wifi, will it return back to 192.168.255.1/24 when I toggle back to wifi?
5. Is there anyway to delete data that has been reported back to the Flukso API server? i.e. bad data from when I first set this up?
I think that is all for now.
Thanks!
Laine.
Hello Laine,
1/ You should set the line voltage of each leg to its RMS voltage.
2/ You can indeed group the three (two in your case) inputs into a single sensor by selecting the 3-phase option. This will map all analog inputs to the first port. You should again configure the RMS line voltage (120V in your case). Please note that for a 3-phase configuration, the configuration of the first sensor will apply to all three analog inputs.
3/ I did notice two spikes in your chart. But they don't seem to occur anymore the last couple of hours. Are you sure this is not caused by a load in your house?
4/ Yes, it will return to the previously configured ethernet IP when toggling back to wifi mode. Just make sure your FLM is up and running, i.e. a blinking heartbeat LED. Should you run into trouble, push the button for longer than 10secs and the FLM will be restored to its original firmware defaults.
5/ Not yet via the web UI. But just tell us which sensors you'd like to have flushed and we'll take care of it.
Cheers,

Thanks for getting back to me Bart.

2. Ok, I may leave it separate for now. I'm curious to see how well I balanced my panel when I wired my house, looks like I did a pretty good job. Our revenue meters only meter based on the two line currents and the leg-to-leg voltage (240V), they don't use the neutral at all, so if you have a severely unbalanced loading between the two legs which creates a voltage imbalance, you can actually get inaccurate metering which in most cases always favors the utility.
3. It turns out they were true loads in my house, it was my girlfriend heating food up in the microwave, she did it twice for about a minute. I feel kind of silly because I was sitting right there playing on my laptop when she did it both times! I never clued in till this morning when I checked the panel to see what circuits on that leg could have caused spikes like that! I did see a spike around 11:40 this morning, I haven't been able to guess what that might have been.

5. You don't have to flush anything for me, it's ok, but thanks for the offer. I'm not going to worry about the my very first Flukso hour when I was tinkering with settings.
I'm happy to be apart of the Flukso community! As you might have noticed, I have lots of cycling, that would be my HVAC equipment (gas furnace, HRV, and steam humidifier), it accounts for alot of my energy consumption which would explain why my electric bills have skyrocketed to over $200/month when energy prices jumped up to 15cents/kwh.

We're now paying 22 EUROcents per kWh. Fortunately, we've managed to lower our yearly electricity consumption to approx. 2100kWh.
