A bonus about this item is that it integrates with Home Assistant and can be purely local (no cloud).

One bad thing is that it's not UL certified.

Useful if you want to monitor both energy consumption and solar export.

Better than Sense?

Sense doesn't have circuit sensors, so you won't have that level of granularity for energy monitoring. Also, requires using their app and relying on cloud data (not sure if they have home assistant integration). If Sense were to go out of business, you would potentially lose all your historical data.

However, sense is UL certified, and I know my solar installer offers installing it for my system (where-as they won't install anything else).

Emporia Vue is also another option and should be UL certified. Works with Home Assistant but cloud only unless you flash the firmware

The Vue 2 and 3 units flashed to ESPHome have been bulletproof for me. I actually just decommissioned my iotawatt in favor of more emporia units to have more expansion ability.

It has a max of 16 input ports (8 on each side). So extra sensors wouldnt have anywhere to plug in

I bought this one and returned it as it was not UL listed/certified. I ended up getting Vue 3

Emporia also offers flexible current transformers for the main bus bars which were required in my setup.

What do you do with the information you collect with this? This looks like more that than a 1 time use to find an appliance consuming too much power.

Keep in mind that UL certification means nothing as far as product performance. It's purely safety related and since this unit is low voltage powered and the CT's are split core, there is not interaction with any system voltage apart from measuring voltage and the magnetic field around your wires. It's like installing a bunch of clamp meters on the circuits and having a multimeter measuring voltage on one circuit to perform the power calculations. While UL is always a must for systems powered by AC voltage, it's not as critical for a low voltage system like this this.

If you like to have historical data (whole house energy consumption, solar generation) this helps you collect the information for that.

While you can use their third party app, I'm personally more interested in storing that data locally via home assistant (server local in your home) and avoiding having my data on the cloud all together. You can view historical data (charts) in home assistant dashboard on your phone or PC (browser).
