Emporia Vue Utility Connect

When I get a bit of time, my plan is to convert it into the newer esphome add-on format. Currently, they dont want to offer ANY support if it is a deprecated external component like it is in its current form.

@monkeyst Has been reverse engineering the v7+ protocol, I am just about to go down that rabbit hole myself as I think I am getting higher than actual watts reported but unsure.

Anyways, thank you for your work @jrouvier , it is greatly appreciated!

@monkeyst I got a new emporia vue connect and it has been upgraded to v 8 MGM firmware, so I am using your .h file. I am seeing a watts reading that seems to be higher than what the original emporia app did and I also see lots of extra data coming through the debug logs. I also see that some meter read messages arent caught because the first char isn’t a ‘$’ → [16:40:34][D][esp-idf:000]: E (22338618) Vue: 0x3ffb2bc4 34 0d 0a 24 01 72 2c |4..$.r,|

I havent had a chance to look at the .h file and go througyh it yet. I did have a different meter div value than the original repo code had and had to write some custom code to get the correct values. I am, assuming my meter div is throwing the reported watts off.

Ill try and take some time this week or this coming weekend to go over the v7 code and see if I can add anything. I appreciate your advice, work and input!

Thanks!

Some of the extra output I am seeing in debug logs (including missed meter reading msg)

@visualage Did the “--before usb_reset” unblock you?

@jrouvier Thanks a lot for doing the initial heavy lifting! I can take ownership (for now at least) at GitHub - nekorevend/esphome-emporia-vue-utility: Alternative ESPHome firmware for the Emporia Vue Utility Connect

@baudneo Not sure about the your “Invalid input at position 1” issue, but regarding the watt reading looking too high, do you have any clue about how much higher it is than it should be? Something that comes to mind is that the V2 firmware had a MeterDiv field where the watt field (and watt-hour?) had to be divided by MeterDiv to get the correct wattage. Oops just read your message more carefully.

If MeterDiv is still a thing in V7+, then for me it is a 1. According to what I had documented, MeterDiv might be at byte 2, 13, 23, or 27 since those have a value of 1 for me. Are any of those bytes possibly not 1 for you?

Ive been kind of poking at it,

            Meter Response Bytes   0 to   3: 18 8a 01 00
            Meter Response Bytes   4 to   7: 00 00 25 7e
            Meter Response Bytes   8 to  11: 83 56 07 00
            Meter Response Bytes  12 to  15: 00 01 00 00
            Meter Response Bytes  16 to  19: 25 00 00 00
            Meter Response Bytes  20 to  23: 00 00 00 01
            Meter Response Bytes  24 to  27: 03 00 22 03
            Meter Response Bytes  28 to  31: 00 00 02 03
            Meter Response Bytes  32 to  35: 00 22 88 13
            Meter Response Bytes  36 to  39: 00 00 04 00
            Meter Response Bytes  40 to  43: 2a 23 05 00

Index 27 is 0x3, So I thought that may be it (my meter div was 3 in v2 struct as well), im going to flash back and forth to get some watt readings to compare. meter div 3 output seems to be lower than expected watts, so I am unsure.

The MGM chip is sending weird log messages, it seems they have some logging component spitting some logs out over that UART as well. Here is some of the message that keeps being repeated.

The logging is drowning the meter readings out as $ is not the first char. I am trying to implement something that will adjust for that.

It would be great if we could get this code switched over to the external component format, that way we can get support from the esphome team. ATM they refuse to help with any issues because this uses the deprecated includes component.

I had an issue upgrading to newer versions of esphome and needed to downgrade to get this code working again. I am stuck on esphome 2024.5.4, unsure if others are experiencing the same.

Yes. Adding --before usb_reset unblocked me.

At least for mine, the display on the actual utility meter periodically shows the current watt usage. Is that not the case for yours? I imagine you could have the ESPHome firmware installed and just stand at your meter and compare it on your phone.

Regarding the log outputs, have you identified a consistent header or byte that it always sends before a log? Could hopefully make the code ignore messages that start with that header. The first line of your example messages doesn’t have the 0x0a, but the rest do… Ideally the header also provides the expected length to read :crossed_fingers:

I did briefly look at converting to the external component format some months ago but dropped the idea at the time due to no familiarity with that format (and admittedly no familiarity with the deprecated format. I only added some C++ to jrouvier’s code.) Just curious, what problems were you hoping the ESPHome team would help with? Is it related to you saying you’re stuck on 2024.5.4?

It seems to me it’s roughly around half of the reported value - ish.

My reason for wanting to switch to the external component for esphome support is, I’ve had some minor problems when upgrading. The ::time issue I put a PR in for and then this newer issue of not being able to upgrade to x.5.

Every issue I’ve opened with esphome is closed immediately and I am told because this code is using deprecated custom_component, esphome devs won’t even look at the issue.

I am the main/only ML dev for ZoneMinder so I don’t have a lot of spare time, but I will try and get this code switched over to an external component format when I get some time.

I tried comparing your meter response values to mine and the differing bytes are at 27, 34, 35, but nothing obvious is jumping out at me about them to suggest “divide by 2”.

(Also noticed my documentation was missing two static bytes at 16 and 40 so I’ve pushed an update for that, not that they help here though)

As far as I can tell, 2024.5.4 is the latest version (which works for me). I guess you’re on some sort of beta release track?

If a breakage is impending then maybe I’ll revisit trying the external component conversion as well. :face_with_monocle:
EDIT: I’ve created a branch with stubbed external component stuff. Will look at it more later.

@baudneo Upon reading more of the V2 documentation, I realize that EnergyCostUnit probably also exists at bytes 34 and 35 in V7. For me the value equates to 1000 since I am billed per kWh. I see for your 0x8813 → 0x1388 → 5000, could you confirm if you are billed for every 5 kWh? Thanks!

I am billed per kWh on my energy bill. I don’t think it is exactly /2, but def in that area.

I misspoke, I’m stuck on 2024.3.2, so I think it was 2024.4.x maybe that has issues. When I upgraded, it was only the vue utility that didn’t work any longer. Downgrading back to 2024.3.2 gets the code working again. Esphome guys told me to kick rocks and get the maintainer to upgrade to an external component before they will even consider looking into the issue.

I’ve reached a minimally viable #WorksOnMyMachine conversion to external component at this branch the main branch, leaving the original implementation as unmodified as possible.

It is certainly not idiomatic to external components and I have no idea how update() is actually supposed to work. My understanding is the system should call update() at the stated update interval (30s in the sensor.py or 15s in my yaml override), but instead it calls incessantly The implementation skips using the update() function for now. (solved :slight_smile: needed to call the parent set_update_interval())

Anyway, these are the important parts of my yaml:

external_components:
  source:
    type: git
    url: https://github.com/nekorevend/esphome-emporia-vue-utility

substitutions:
  name: Meter

uart:
    id: emporia_uart
    rx_pin: GPIO21
    tx_pin: GPIO22
    baud_rate: 115200

sensor:
  - platform: emporia_vue_utility
    uart_id: emporia_uart
    update_interval: 15s
    power:
      name: "${name} Watts"
    power_export:
      name: "${name} Watts Returned"
    power_import:
      name: "${name} Watts Consumed"
    energy:
      name: "${name} Wh Net"
    energy_export:
      name: "${name} Wh Returned"
    energy_import:
      name: "${name} Wh Consumed"

I’ve listed out all 6 sensors you can choose from, but you probably don’t need all of them.

If you try it out, I would give the name some value like Test so potentially incorrect values don’t infect your sensor history.

Awesome, great job! Going to try out the new code this evening.

Edit: It works for me!

The only thing is, I must have a newer v8 version of the firmware that also outputs some log messages on the UART between esp and MGM. I will try and modify the reading code to look for the meter responses amongst the other log output.

Thanks for your work @monkeyst

It’s interesting that the log message seems to be inserted into the meter response “packet” (though with a huge gap) according to

[21:21:11][D][emporia_vue_utility:407]: Meter Response Bytes  44 to  47: 0d 00 00 00
[21:21:11][D][emporia_vue_utility:407]: Meter Response Bytes 256 to 259: 53 65 49 68

If it’s always trailing a response packet like that, perhaps the answer is in here:

        default:
          if (pos < data_len + 5) {
            ;
          } else if (c == 0x0d) {  // 0x0d == "/r", which should end a message
            return pos;
          } else {
            ESP_LOGE(TAG, "Invalid terminator at pos %d 0x%x", pos, c);
            ESP_LOGE(TAG, "Following char is 0x%x", read());
            dump_serial_input(true);
            return 0;
          }

Specifically, maybe this change would do the job of wiping out the log message part of the “packet”:

          } else if (c == 0x0d) {  // 0x0d == "/r", which should end a message
            dump_serial_input(true);
            return pos;
          }

BTW, I see you added Meter Divisor: 3 to the debug print that prints once at startup, and it might interest you to add debug: true to the YAML so it prints on every message :slight_smile:

  - platform: emporia_vue_utility
    uart_id: emporia_uart
    debug: true
    update_interval: 15s

I am noticing that the e type message seems to be an out of range/no connection to meter. My test bench is on the other side of the basement and the connection is spotty.

Got it, can confirm I also tried moving mine farther from the meter and started seeing ‘e’-type messages again.

I’ve updated the doc and log output to suggest moving closer to the meter.

Have you figured out the wattage divisor?

Yes, I forgot I found this issue in V2 and fixed it:

   watts >>= 8;
   watts = ((float) watts * (float) meter_div) / ((float) cost_unit / 1000.0);

Neat! Pretty strange and I hope it applies to everyone. Seems fine for me so I’ve updated the code here: Support MeterDiv involvement in Watt calculation. · nekorevend/esphome-emporia-vue-utility@b47be07 · GitHub

Looks like V2 uses meter div for watt-hour calculation as well. Did that need adjustment for your setup too?

I’m not sure about watt hours, haven’t checked the data to compare yet. I will take a look this evening.
