Yes, I appreciate seeing the other data, not only the voltage but also the wattage and the frequency.
Can you venture a guess as to what the Sense spec’d frequency range might be?
Do you know who might be able to tell me what the Frequency range is set to on my monitor?
I like your graph, including the colors. What are each of the colored lines reflecting? It’s interesting that the voltage would drop so tightly with the 48 A EV charging; sure does stand out.
What drove the read and the blue apart on Nov 22 at around Noon?
Maybe I will have the head space and time to get Home Assistant up and running here some year.
The Sense Wattage provided me an opportunity to solve a puzzle the other day.
I look at both the Tesla app and the Sense app multiple times per day as components of my off-grid solar electrical system management, along with weatherbug for the solar insolation / cloud cover info.
Usually, Tesla and Sense are reporting the same power usage but the other day, Sense was showing more than 2000 watts over the Tesla report.
Where were the 2000 Watts going? It would be nice if Sense could have answered that question for me but it only increased the “Other” bubble on the display as it spiked the Power Meter graph.
So, I went through my head for clues about something that might still be on that would draw that amount fo power. I went around shutting things off, turning them back on and found out it only happened when I switched on the 240 V electric Water Heater.
Sense detects it sometimes, revealing ~ 4000 watts draw. I primarily use the electric water heater as a storage for the surplus solar electricity; it also keeps the Tesla inverter from increasing the frequency to stop the flow of DC solar electricity from the SMA inverter (62.5 hz - solar curtailment).
Anyways, when I flipped the water heater switch … Sense detected it and the 4000 Watts it draws. But it also detected the mystery 2000 Watts in the “Other” category.
I went through a lot of steps including flipping the Sense breaker, removing and unplugging the CTs, checking everything else. I plugged everything back in and tried to run the network connection test. At first it told me everything was good, I was connected to ethernet, but when trying to finish the test it told me I didn’t have a connection. (?).
The blue light on the ethernet to Sense monitor was flashing so I figured it was still trying to connect.
So I figured I would give it some time but still no go after a number of minutes.
No biggie, sometimes it seems like the monitor is bugging. But, I am told by Sense support folks that they check it during their process and that it is always fine. (I wish they would send me another one to rule out any problems with this unit.)
Anyways, on my first go around I had not unplugged the cat5 ethernet cable so perhaps it losing connection was somehow a coincidence with the 2000 W mystery draw.
I securely plugged both ends of the cat 5 ethernet cable back into the appropriate ports.
And, waalaah, I had a good connection and the mystery 2000 W draw was gone.
I have been connecting wireless since the beginning but hooked up the cat 5 ethernet to see if that would solve the gaps or data drops in my power quality graph. I will remember to double check those connections if the monitor starts behaving off-kilter again.
I still don’t if the cat 5 ethernet cable has solved the erratic power quality with frequent drops cause I the power quality graph is still stuck on November 10th.
And, I still don’t know what was causing the reported 2000 W mystery draw.
BTW, the sun has come out again and the two Tesla powerwall 2 batteries are 99% fully charged, the frequency is shifting up to 61.9 - 62 hz to shut down the flow of electricity to the batteries and the house. During such times I have to think about what I can turn on to use the blessed electricity instead of having the system stop the flow.
So, I also appreciate the Sense frequency data; just wish it wasn’t buried so deeply in the app reports.
I’d actually like to see the power quality graph (wish it could be real time) with the two voltage lines and frequency on the main page rather than the bubble map.
Of course, now I wish I could see the power quality patterns in any location. And, I wish I could speak with someone at Sense who could give me some straight answers instead of kicking me around to different people with different answers.
At least that is how I feel but usually I just keep myself distant from all of that and just utilize the data that is available. But, I feel the loss of the power quality info and graph.
Are we experiencing the death of the power quality lab?
