There are quite a few things that could be happening - any causes I share would just be speculative on the cause of a missed detection of your pool pump. I have a few questions for our Data Science team before I share some of the things that could be happening here.
Unfortunately, I don’t know a lot about the Direct Drive garage opener. The 63 page product technical specs i looked up for it look like it’s a 3/4 HP / 1HP motor.
You can see how difficult this gets based on the variations of available residential electronics and appliances - there are tons of options out there and reviewing each of the technical specifications get pretty untenable.
One more note. It’s not how long devices run, but how many times they turn on and off, that educates Sense. In some ways, running for 9hrs continuously could impair learning - the on is separated by the off by a lot of time, and that also reduces the number of repetitions. But a lot depends on the overall shape of the on and off transitions as well.
That is why it feels logical that if you could switch something on/off 20 times you could “learn” sense something about a device.
I would bet people would be willing to even turn off the rest off the house ( no other traffic on the highway). To let sense listen to it in detail.
chris.angeline.gross… Wanted to chime in right away, but I waited to let the smoke settle… Hi… I only come to the board in the morning once…EDT… Sure a lot has been said what I am going to say, But not going to sort it out… Just a couple of things…
Think the pool pump has to have a number of cycles everyday in order for it to be found. Once or twice a day is not going to cut it… Just my thought here…
The LG frig… We have had 2 with the linear compressors. Also both have been going through APC UPS’s. The first LG was about 6-7 years ago. Put it on a computer type APC UPS… Tall narrow. Maybe modified square wave… 1000 watt… This was on it 24/7…(more later)… Sense found it…frig and also found the defrosting cycle separately. I think the defrost comes on about every 20…Twenty… hours or so… Crazy cycle.
The second LG frig… LRMVS3006S…Was put into service last April '21. It is going through a different APC UPS… It uses a APC Smart-UPS C 1500VA LCD… Believe it has a transformer in it and will give more of a ‘pure sign wave’. It is low profile and boxy square. And heavy… Now this is not on the ‘grid’ 24/7. Got our solar going last summer with the stay home… It is not being seen by Sense from about 7 in the morning until 11 at night. That is when it is on our solar generator. So not being picked up by Sense because of the new APC or the less time on Sense. Not sure yet, but hope one day Sense will pick it up.
Ok… Please don’t put a refrigerator on a UPS. They are not rated for the startup draw that a fridge can pull. They can catch fire if over drawn. I’ve seen this happen in server racks a couple times.
Second, the UPSs that you can purchase under 2k do not have always on inverters and therefore only deliver pure sine wave while on battery. They will however attempt to condition the power or supplement when there’s a brown out, but it’s a complete move from grid to battery.
There’s really no reason to have a fridge on a UPS. The max run time wont equate to spoiled food without it. If you’re concerned about food spoilage grab a small Honda inverter generator. They are quiet, very efficient and have a low total harmonic distortion making them suitable for sensitive electronics.
Lastly, a residential grade UPS has no impact, positive or negative on Sense discovery as it only passes power through, unless on battery.
I read that smart plugs are NOT recommended for refrigerators. A couple of reviews claim that they can cause fire hazards. I also have a high end LG fridge (LRMDC2306S) with wifi. I communicate with LG ThinQ phone app. Could Sense communicate with the LG in the future just like ThinQ?
That would be cool if Sense could make Sense of smart appliance power usage, especially since I have an LG smart washer and dryer that talks to ThinQ as well. But I’m not holding my breath. Why ? Most of these smart appliances use proprietary communication and likely provide samples at far too slow a rate to fit cleanly with the Sense UI. My smart fridges (SubZeros) once offered a “true” industry standard, Smartgrid-ready: ANSI/CEA2045 and the USNAP alliance, for power measurement and management. But that standard went defunct due to poor targeting and lack of value to enough stakeholders.
Not sure where you saw that, I know of no such limitation and as an electrical engineer can’t think of any reason that should be a problem. I’ve had my Sears variable speed refrige on a Kasa plug for years and it works great.
I hope the specifics include a “not correct” button so Sense can continue looking for what it really is. Sadly four kitchen appliances register as “coffee maker” and when the rice cooker comes on I can’t tell it “NOT coffee maker”, at least I haven’t found that button yet.
