IoTaWatt VS Home Assistant

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.

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.

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.

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.

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.

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).

Apparently the same issue has been reported with Philips TV [1] and Fritz!Box [2] as well.

The plug would transmit power readings to my Home Assistant setup.

Home Assistant can cast dashboard/media/etc to your display and has shopping lists. https://www.home-assistant.io/

If you provided MQTT support like plenty of IoT companies do, then any open source home automation tool can integrate! Home Assistant (https://www.home-assistant.io/) have a grading system, so a local-first implementation would give you their highest score since they also really care about privacy. https://www.home-assistant.io/blog/2016/02/12/classifying-th...

It's hard not to raise a little smile at Google's automation scripts, which bare a not-entirely-passing resemblance to those of a certain other, more comprehensive home automation system...
