Setting up Emporia Vue 2 with ESPHome
The instructions for the Emporia indicate that it doesn't matter which of the three 200A circuits you plug into. I am in North America so there are two 200A clamps and it does indeed matter how they are connected to the Emporia. With the configuration script shown in this article, one needs to use inputs A and B.
Yes I know they are called A and B in the configuration but I didn't make the connection ....
While the instructions allude to the fact that you need to keep the legs sorted, I would like to stress that it is important not only for the current clamps but also how you hook up power to the Emporia. If the power leads to the emporia do not not match which 200A clamp is on what leg, readings might be wrong or you might have no readings at all. The black Emporia power wire needs to be on the same power distribution leg that has current clamp A on it. The red power wire needs to be on the same power leg as the clamp that feeds input B.
How does HA know when to reset daily energy numbers? My new install doesn't seem to reset at midnight.
The instructions for the Emporia indicate that it doesn't matter which of
the three 200A circuits you plug into.
It doesn't matter because you can then change things in the configuration.
But yes, if there's a mismatch between configuration and the real world,
there will be problems
How does HA know when to reset daily energy numbers?
ESPHome does the resetting. By default, it gets the time zone from the
system. If you're running the ESPHome compile inside docker or something,
you might need to manually override it. Take a look at the ESPHome docs
about time.
*from the system it is compiled on.

Thanks for all the work getting this working!! I spent about 5 hours thinking there was some way I could get it to compile on a raspberry pi 4 with 4gb ram- including switching to the 32bit version, but it still wont work.. So in the end I relented and am now running home assistant on a 7 year old i3 intel NUC and it works great!! I definitely recommend anyone wanting to use this currently in a standalone installation to just buy a used intel NUC for < $100 on ebay and be done with it... Going to try get it working with three phase inputs some time soon, not sure how hard/easy that will be.
EDIT > looks like it works with three phase just by adding in phase C in the config file! awesome!
I spent way too many hours on this ... but in the end, my method works great and I still have my original Pi4 running HA.
I spent way too many hours on this ... but in the end, my method works great and I still have my original Pi4 running HA.
But can you change the ESPhome settings from the RPI4? that is my main reason, I anticipate needing to re-compile and update, and will have remote systems running this etc..
Edit > I'm not saying one method is better than the other, just saying for me this is overall easier and more maintainable, at least until we can compile it on ARM..
No, I would not be able to change the configuration from the Pi4 .... that would require a recompile which can't be done from the Pi4.
I installed ESPHome and the dashboard on one of my laptops. It just sits there ready for use. If I need to recompile, I just start up ESPHome, go to the dashboard, load te configuration file, tweak it and send it back to the Emporia - no muss, no fuss, I just have to remember to do it via Chrome instead of my normal browser (Thunderbird).
I recompiled a whole bunch of times as I was setting everything up so yes, you absolutely need to be able to recompile and send te result to the Emporia. I am still working out a couple of issues and expect that I am not finished configuring things.
BTW, I did not try generating the .bin file on my laptop, transfer it to the pi and then send it to the Emporia. That should (in theory) work but it's an extra step that is not really required.
Does anybody else have issues with 'daily energy' never resetting at the end of the day?
I did need to set my own sntp server (network doesn't allow traffic to the outside) but that didn't help. Looking at the logs from the Emporia, every message has the correct time in front of it.
Let me clarify this a bit - if I look at the 'energy' dashboard, the daily energy is correct. I have an 'entities' card set up in one of my dashboard views and it shows individual circuits and individual daily power usage (and total daily power usage). It is those totals sensors that do not reset.
Platfom 'Total Daily Energy Sensor' states:
# Enable time component to reset energy at midnight
time:
- platform: sntp
id: my_time
From what I can tell, the time platform is working as every single status message from the Emporia has the correct time stamp .... but maybe that time component is different from the time that shows up in the logs - how do I check if id: my_time is correct? my_time is not an entity or a helper so how can I verify it?
Does anybody else have issues with 'daily energy' never resetting at the end of the day?
My daily energy value also did not reset at first. I don't know exactly what I did to fix it. It may have started working on its own at some point after a few days or maybe a week. I do remember that I changed the time platform from sntp to:
time:
- platform: homeassistant
id: homeassistant_time
This is working fine for me and is syncing time via home assistant. I have my emporia vue 2 on an isolated VLAN which doesn't have internet access, so sntp probably wasn't working (my DHCP server hands out local ntp server info, but I think most devices ignore that).
Thanks for that mgulick. I tried that this morning but this gives me a compile error which is likely due to me having to compile the Emporia configuration on a computer other than the computer running HA.
It is good to know I am not the only person that has/had daily reset issues.

Is there another location, discord or an issue somewhere, that these things can be discussed. I'm honestly watching this gist in case there are changes or issues with the integration itself.
You could just watch the Integration source repository that is linked to in the example configuration. Not sure where else to discuss issues as there is no issue tracker?
changes or issues with the integration itself.
@Jens5395, I would frequently have compile errors when rebuilding after making changes to the configuration. Cleaning the build artifacts usually resolved the issue. It looks like this option is called "Clean Build Files" from the ESPHome dashboard (https://esphome.io/guides/getting_started_hassio.html) and esphome clean <config> from the ESPHome CLI (https://esphome.io/guides/cli.html#clean-command).
Ha!!!! That did the trick, it compiled! Now to see if it fixes things at midnight ....
Thanks!
@clowrey sure, my point is that these issues are not related to the Emporia Vue.
Please keep all discussion here
Hey y'all, I've had my own gripes with Gist as a discussion platform as well.
Any further comments here will be deleted and recreated in https://github.com/emporia-vue-local/esphome/discussions. This will be the last comment on this gist.
@rjchu, Yes mqtt is working quite well - I use FHEM (https://fhem.de/) hence mqtt is my choice of integration in this case.
Btw, unlike the emporia app which only calculates apparent power on the 16 CTs, this implementation is correctly measuring real power - thank you @flaviut !
sudo docker run --rm -v "${PWD}":/config -it esphome/esphome version Version: 2022.6.0here is my draft config - still making design decisions but working quite well already. the send times are temporarily set too low, I plan on every 10 secs for instant and every 5 mins for totals, etc

Hi. How is your setup working with 3 phase?
Just bought a couple of emporia and noticed the yaml is setup for 2 phase, not 3.
Good morning
VUE 2 modified with ESPHOME.
same as VUE2.yaml. on home assistant virtual machine works well.
on ihost modified Home assistant returns:

@fabiopbx the current reading doesn't work. I've never been able to figure it out, and there's been some past
discussion where others couldn't figure it out either. I would recommend against using the current sensor.I'd suggest you use a multimeter with a current clamp (don't touch any metal with your fingers! this stuff can easily kill you!)
to see what's going on and if the kW reading is inaccurate. If you want current, you can always calculate it using power/voltage.
Hello @flaviut,
Are current readings ok now ? What should I add in the yaml in order to expose
them in HA for the small 16 clamps ? Because I'd like to give a try to the following :
emporia-vue-local/esphome#287 (comment)
Thanks in advance for your input. Best regards.

Final entry:
For reasons unknown to me, the Emporia configuration compiled, was installed wireless and seems to function. There was a computer reboot involved so that might have fixed whatever was causing the compile errors.
To sum it up, a pi4 64 bit HA server configuration can not compile the Emporia Vue 2 configuration via ESPHome. It can however generate a configuration stub that, once uploaded to the emporia with a wired connection, will allow the emporia to connect to the network via wifi.
Now that the Emporia is on line, the Emporia configuration can be built. This is done, in my case, on a Ubuntu machine that runs an Intel processor and has the required tool chains available.
I installed ESPHome and ESPHome dashboard on my computer (the one wit the Intel processor). Note that there was only ESPHome installed and no Home Assistant files/system. I started up ESPHome, went to the dashboard (btw, you can also do this without the dashboard and I think I read that the dashboard only works on Linux) and generated a new stub for the Emporia. I then copied the configuration as shown in the article here into the stub, over-writing the temporary stub (it was just a place holder). I adjusted the wifi parameters for my setup. There are a couple of gotcha's here. My normal esphome configuration files use !secrets for the ssid and password. This will not work because we are compiling on a computer that does not have these HA options available. The ssid and password must be hard coded into the configuration. I also had to set up static IP parameters in the configuration in order to make this work .... although I can't recall the exact reason. All my esphome devices have static IP's set up in the router so hardcoding a static IP in the configuration might not be required. YMMV.
So, we have an Emporia device that is on the network and we have a configuration file set up on the Intel computer. All that is required now is to install the new configuration to the Emporia.
If all goes as planned (and not like in my case), the configuration will be compiled, uploaded to the Emporia that is on line already and when finished, the Emporia will reboot and spew out all kinds of data which will be captured in the Home Assistant system running on the Pi4.
When you set up the hard coded credentials, please note that the SSIDS field is case sensitive. I new this was so for the password but did not realize that this was the case for the SSID. That error took me WAY too long to find!
I hope that this might help future HA builders to set up an Emporia device without all the crap I went through .....
