What's that touchscreen in my room?
If anyone is interested in having this type of real-time usage data for their own own home, I highly recommend IoTaWatt: https://iotawatt.com
It's a completely local energy monitor that you can install into your home's circuit breaker panel, and then view dashboards or read data via an API from a local web server running on-device. You choose how many sensors you want, but you can monitor your whole home as well as individual circuits.
For example, I track and trigger automations when my various appliances (laundry, dishwasher, microwave, etc) start/stop. It's very cool. Just be warned that it does require some research, basic understanding of electricity, and comfort working with high voltage mains connections if you plan to DIY it but I found it approachable and easy to setup.

Has anyone here switched from flat-rate to peak-hour rates (or vice versa) with Duke? What has your experience been?
I use an IotaWatt system. It's super easy to install and manage. It uses inductive sensors at your circuit breaker so you can see your total usage and per circuit usage. It also easily hooks into HomeAssistant but that's a bit more advanced of a project.

Smart whole home energy monitor? DIY installation.
I have an IotaWatt and am pretty happy with it. It was not the cheapest option; but is simple, reliable, and local only which checked all my boxes. I did install it myself; BUT this involved opening up and poking around inside my breaker panel. AFAIK this is pretty much required for any per-circuit home power monitoring. Insert "The power inside your breaker panel can kill you instantly and painfully" warning. My panel is mounted on the wall (rather than inside); and I guess I could have put the clamps on the wires where the exit the panel. But it would have been much harder to identify circuits. Also it would probably be much messier.
- Any suggestions what is happening to my electric bill??
- Can someone tell me what this reading is? My electric bill quadrupled this month.

Home Energy Monitoring Dashboard
For individual circuit energy monitoring, I use Iotawatt. This involves installing CT clamps in the main breaker panel to monitor the circuits you want to monitor. I’m comfortable doing it myself but if you’re not, DO NOT mess around with it, hire a professional electrician instead because you can get electrocuted.

Power draw over 1kW higher in the evening/night.
If you really want to mail down your sources of current draw, I can’t recommend this enough: http://iotawatt.com

CMP Strikes! After years of equal monthly use, CMP said our use DOUBLED in March. We were on vacation for 1 of 4 weeks. This is impossible. Anyone else see this? I'm considering filing suit. (I'm a lawyer).
Since you have home automation, you may already know of IoTAWatt - it's a little cheaper than others, and works really well on its own or with HomeAssistant etc.

Is Sense accurate, and can it be trained?
Sense is really good at measuring overall usage. Their neural network analysis to identify individual devices is anything but reliable. If this is important to you, I suggest you monitor individual circuits with something else (eg. iotawatt).

Discharging to Zero
FWIW the API (https://github.com/vloschiavo/powerwall2) reports a state of energy greater than 0 (5% I think) when the app shows you 0%. i.e. there’s a lower buffer. I understand the anxiety seeing them at 0% though.

Hi. We just got solar from Tesla. 14.4kw system and 3 powerwalls. Is there a way I can see each powerwall individually? All I see is the percentage and x3. I’m trying to balance it to where we run on powerwalls all night and have enough reserve power to get through a short power outage if necessary.
You can see individual powerwall stats using the local gateway API: https://github.com/vloschiavo/powerwall2

Tesla API
See here for documentation: https://github.com/vloschiavo/powerwall2 Additionally, Home Assistant has out-of-the-box integration using this API. Note that you must have a backup gateway/powerwall for this to work.
