Leviton LB120-DS 20A 1-Pole Plug-On Smart AFCI/GFCI Branch Circuit Breaker, Hydraulic Magnetic, 120 VAC, White

I bought this as breaker for my Tesla wall charger. I wanted to verify how much power it is using, and also have the ability to monitor that over time as well as be able to trip the breaker remotely should some random passer by decide to plug in to the charger. This is obviously only usable in the leviton smart panel application. But it does work well.

The Leviton Load Centers are great, but some of the double pole smart breakers, the -GS or -ES models, do NOT work with 120/208v systems. Only the standard -S varieties work. Disappointing!

BLUF: I think these are worth looking at if you are already going to replace your breaker panel, if youre looking for energy monitoring only, look into something else like the Sense Energy Monitor (which also has pros/cons). You dont have to have smart breakers, but I like seeing the energy usage for each breaker. The Leviton smart breakers (I have only a handful right now because they are pricey) allow you to receive near-real-time notifications (SMS Text and Email) about the status of your breakers (IE if a breaker is tripped or turned off, you will get notified). You can also monitor the current draw on each of them independently (See picture) as well as receive notifications of high or low voltage. Pros: 1) Smart - Remote Monitoring, bill estimate (with user input) 2) Notifications - trip notifications, status updates (IE: turned on/off), high/low voltage, Self-test failure, and other various 3) Design - If youre tired of the old gray box, this offers a sleek white casing that has a windowed front cover (additional cost) 4) Data hubs can be wired or wireless internet access 5) No wiring to the breaker itself, each connection is made through the lugs on the back of each breaker as you plug it in (up to 6awg 60 amps). Cons: 1) They are expensive. $58 for base (non GFCI/AFCI) single pole SMART breakers and $90 for base (non GFCI/AFCI) double pole SMART breakers. AFCI/GFCI smart breakers are more expensive topping out at $122 for a single pole smart AFCI/GFCI and $162 for a double pole smart GFCI breaker. (NON-SMART breakers are more reasonably priced at $11 single pole and $17 - $22 for double pole. 2) They require the Leviton Load Center breaker panels 3) They do not come in half breakers, each space requires a full space (other panels offer half size breakers to double capacity). 4) To get smart monitoring you need to get 1 x data hub per breaker panel (So if you have a main panel and a sub panel, you will need to get 2 data hubs), they are $149/ea. Bottom line: If you want smart monitoring you have options. Obviously this is the more expensive option as replacing a breaker panel could run more than $3000 for a panel, cover, full set of smart breakers, and installation costs. I opted for this option because my old panel was full and I needed more space. I could have used a sub panel in the utility room but I already have one in the garage and didnt want to have multiple sub panels. If you want independent breaker monitoring and/or control, I have not seen a better option.
