Sense has allowed me to reduce my electricity consumption, identify electrical issues, and reduce my electricity cost. E.g:
- Replace all incandescent and halogen bulbs with LED.
- Replace old pool pump with an efficient variable speed pump.
- Identify a failing AC compressor capacitor.
- Help perform data analysis of PG&E's (my electric company in California) set of residential tariff options.
- Influenced behavioral changes; make use of major appliances during off-peak hours, and to pre-cool my house (run AC) earlier when the sun is still allowing my solar system to generate sufficient power and/or during non-"peak" hours.
- My next project is to hunt down my 484W Always On vampires.
If you've had your solar system installed in the last 5 years, you can request to be kept on the EV-A tariff and benefit from its much more solar consumer friendly rate plan, but you have to contact PG&E to get grandfathered.
Regardless, look into your local electric company's tariff options to see which is best for your consumption and generation profiles. I expect many electrical utilities will continue to make their tariffs more hostile to solar customers (and more beneficial to their grid...which I understand), even when they keep net-metering fundamentals, and that we need to be more vigilant to determine the best tariff option.
One of these days, I hope Sense will support TOU (and tiered) electricity cost mechanisms, so that its electricity cost feature is actually useful. In the meantime, exporting Sense consumption and generation data, and doing offline data analysis, in Excel for example, is an option.
