Well, where does this stand?  I need to have a local data feed.  If the internet goes out.  I have no data. The internet often goes out when the power goes out.  My generator kicks in but now I have no power data to guide the regulation of power loading.

Give me a local data feed that I can feed to my NAS or MQTT server.  Give me a local web page directly from the ESP32.  That would be easy for your to do.

I need a 2nd 16 channel device but I am not buying it UNTIL I get a local data feed.

What happens if Emporia goes out of business?  All the cloud data stops.  That’s what happens.

Giving users local data is the most important confidence building update that Emporia can do today for its current and future customers.  I have already told 4 people not to buy Emporia simply because of this.

Yes,  I understand VA is just that.  Volt x Amps = Watts.  Yes again, Amps are much easier to determine with a DC voltage and a pure resistive load.  Coming from the Vue 2 CT is a small AC voltage.  Looking at the circuit board, it looks as if this is half wave rectified and smoothed (not sure because I have not traced out a full schematic).  This is always going to be approximate given varying load types.

My Fluke is a fairly old model that I have had  for decades and I do not think it delivers a true RMS amperage reading.  However over the years it has been pretty consistent measuring everything from incandescent light bulbs and heaters to 5HP motors.  I trust it.

Given what you say about how the Vue 2 derives its AMPs reading I am not at all surprised at the difference.  I need the Amps reading on a per second basis to calculate phase (well the 180 degree difference between the ends of a transformer winding) so as to know what I can switch on or off when running on my 7,000 Watt inverter.  This was the reason I bought the Vue 2.

I shall try this test again with a much newer true RMS clamp meter this weekend when a friend brings his one to my house.  More then.

Due to UK ring mains wiring, most UK fuse boxes (Load Center in US) have very few fuses.  I was born in the UK and now live in the US.  It may be more useful in the UK to use fewer CT sensors and more Smart Plugs as well as having a CT on the Main.

You are right UK fuse boxes are very cramped and quite a few still use real fuses, not breakers.  There is no reason why such installs should not be a success albeit with slightly less granularity than US multi breaker systems.

Another vote for a no cloud install.  Why?  During power cuts my AT&T fiber internet often goes out even while my 7,000 Watt generator/inverter running my router and all the rest of my LAN/NAS and other bits of electronics.  The main reason I bought a Vue2 was to monitor my loads before and during running on the inverter.

Even if Emporia just gave me a real time webpage from the ESP32 I’d be happy but I’d rather not be using somebody else’s hard disk (sorry, cloud) at all.

Surely after the time this thread has been running Emporia could do this.

Thanks to all for your replies.  My Inverter runs the entire house but, not everything at once.  This is why I need the Vue 2.  My router, Ubiquiti WiFi and all necessary electronics will all be running during a power outage.  The problem here is the AT&T fiber often goes out with the power.  Last time a truck hit a power pole and this severed several “cables” including the fiber optic to my, and other, subdivisions.  The Vue 2 is powered from the inverter too.

I do have UPSs and they hold up my stuff for long enough to get the generator/inverter running but that is not the issue here.  The lack of incoming internet is.

All I really need is a simple webpage on the Vue 2 showing real time data if I cannot see cloud data.  This may also be an issue for those using off-grid systems, satellite internet excepted, of course.
