The individual circuit view has really helped me find some major drains in my house that I don't think inwould have found with a whole house solution. Something like a dieing refrigerator compressor suddenly using twice as much energy wouldn't show up on a whole house but is noticeable on single circuit tracking.
I know nothing about this company, but if their products are only available at Aliexpress, Amazon, and eBay, that's probably not a good sign.
Also, the Vue can be flashed with esphome which is nice if you're in that or the HA ecosystem.

Does anyone have an energy monitor from this company? I like the idea of a smart energy monitor but haven't done a lot of research

Interestingly, there does seem to be a Home Assistant integration for this company: https://www.home-assistant.io/int...ns/refoss/

The energy monitoring model it specifies is the EM06 tho, which looks like an EU version, so no idea if it would work.

I have a Meross garage door opener in my house and it works great. It says sold by: Meross Ecommerce so I don't really know if that means it's the same company or something else.

I think for the $30 difference I would still go with Emporia Vue (or similar).

The device itself looks almost identical to the Vue (except it's orange).
The software looks different but likely just a different presentation format.
I have the Vue and it works great and can be integrated with Home Assistant.

How easy is it to install? Do we need to hire certified electrician?

It looks like all the probes are non contact. However, you'd have to take the panel's front plate off.

I would consult an electrician as you're getting too close to the bus bar and unless you can go to the main breaker upstream, it's not worth the danger.

Edit: I'd wait for a few early reviewers to do the testing for me, even if I have to pay $30 more later. But overall, I'm happy to see devices like this being developed. It's about time!

Same here, I had to talk to their CS and it was actually seamless to do. Someone who knew what they were doing actually replied back and it wasn't the typical scripted response.

That was 3 years ago though. Lol things might have change, who knows.

Isnt Vue depends on cloud? Or is it complete local? If it's complete local, how does it communicate to HA via wifi or zigbee or something similar which requires hub?

Do we really need energy tracking per circuit? Can we not directly 'read' from electric meter outside using RF or espCAM?
IDK, I really liked seeing how much energy my dehumidifier (and old freezer) was using before I replaced it with a newer Energy Star model. I'm using the Sense/Wizer system (with some TP-Link smart monitoring outlets). That install does install to the panel in 2 open braker spots. Good to see some new tech coming in.
