I’m building a new house with solar, battery, generator, and grid tie in. Originally was planning to go with the span panel, but now considering this panel. I’m not purchasing batteries compatible with span, so automatic load shedding would not work anyways, I was going to have to create my own automations in HA. My question, what are your thoughts and is this integration far enough along, I can go with Leviton and accomplish rules in HA to accomplish load shedding?
I have the new Leviton LWHEM-2 which unfortunately doesn’t have ethernet. I did a quick disassembly of the unit and it looks like there is a main unit with a BLE radio that connects to a separate unit with a WiFi.
I guess I could try to sniff the (serial?) connection between the wifi and the BLE radio, but perhaps I can force it to the “access point” more state while connected to the wifi still by blocking the leviton endpoints.
Will give it a try and report back.

Well, blocking the wifi didn’t work, unfortunately. Now I wish I got the LDATA unit. Will debug more and report back.
I heard the LWHEM-2R has ethernet. Anyone tried that?
I just got the LWHEM-02R and it does not have an ethernet port.
I’ve just recently been doing some work with the LDATA, which proved fruitful. I’m reasonably certain I can keep the API enabled when wifi is on, though it requires jumping through some hoops.
I’m pondering replacing my panel with a Leviton + LWHEM, though, and I’d like to verify if I can do the same on the new one. Would you be willing to share the internal photos you took as a start?
If there’s anyone who has an LDATA installed and is willing to do some testing, please get in touch with me. I can definitely show you how to keep the API enabled even if you’re on wifi, but I found a couple other things I’d like to investigate with someone who has a unit installed.
I’ll install Leviton load center like one of sub panels in my house.
I have both variants of smart hub.
When I will install it I’ll contact you.
Unfortunately I have only stupid breakers and v.2 breakers: that one you can ON and OFF.
V.1 breaker you can only trip.
V.1 hub has Ethernet connection.
V.2 hub has only wireless.
Any updates to this thread?
I want to install a Leviton sub panel in my house to monitor some breakers. I’ve been following this thread for some time.
Does the LDATA contraption work with Gen2 breakers, or only Gen1? e.g. if I get Gen2 breakers for remote on capability, do I have to get the LVEHM or can I still get the LDATA to work with to collect data?
Is the only benefit to the Gen2 breakers the ability to turn them back on remotely?
I don’t have any Gen2 breakers but I have 4 panels; 2 main and 2 sub, and a LWHEM-2 in each one, and it works with this integration. The data is somewhat iffy but I suspect it’s at least partially influenced by the fact that we have solar and the Leviton app itself can’t properly manage it. I don’t have any of the smart breakers so interested in your experience.

I found these posts on Reddit helpful:
https://www.reddit.com/r/smarthome/comments/1gc8g9r/leviton_load_center_local_access_to_data_and/
tells you how to modify the ldata to allow the api server to run alongside wifi.
did you ever figure this out?
I’ve got all new construction after a major house fire and I’m putting in Solar with Battery Backup. I wanted to set up the main load center so that if we lose grid power and the inverter switches to battery that HA would be able to tell certain breakers in the load center to shut off.
Is that possible with the Leviton load center and the LWHEM-2?
Does the LDATA work with gen 2 breakers?
The panel is already installed and wired, but we haven’t put up drywall yet. I don’t want to tear it out and replace it with something like span, but if there’s no other way then I will.
There are definitely differences between Leviton and Span BUT I’d say you are better off with Leviton. The only challenge I’ve had with HA is it only seems to support 3 panels, and I think that’s more an issue of Leviton APIs than it is HA. But for every panel we have a whole home energy monitor and where we also have smart breakers I can see all of their individual utilization.
Would recommend.
I got Leviton load centers for the breakers in my house, which are backed up by our home battery; one panel has been in for over a year, and the installation on the other just finished today. My plan all along has been to do exactly what you’re suggesting – if a grid power loss occurs, switch off specific breakers so we are only pulling from the battery for the most important things (refrigerator, internet modem, basic lighting).
Since most of my most impactful loads (heat pumps, water heater, exterior lighting) are on the panel that just got installed today, I hadn’t set up my “in case of power failure” automation yet. But as a first step, I have long had an automation in HA set up to detect when the grid is cut and battery backup starts; so far, I just get a notification from HA, but my next project will be to also instruct the Leviton integration to switch off breakers. The option is pretty straightforward, see screenshot (this would shut off air conditioning, as an example).
I have 2 Leviton load center panels and started with the LDATA modules in each and then upgraded to LWHEM-2 and that’s what I’m currently running.
I did all of that work before finding this thread and learning about this integration so I’m going to set the integration up with what I have and see what I get.
I can say from experience that the LDATA will work with the Gen 2 breakers, but it won’t recognize any of the advanced features - it will see Gen 2 breakers essentially as Gen 1 breakers. Same goes for the LWHEM-2 … it will work just fine with Gen 1 breakers but there is zero additional functionality to be gained from the Gen 1 breakers by upgrading from the LDATA → LWHEM-2… you need both the LWHEM and the Gen 2 breakers to be “current” and have all the listed capabilities.
