Tasmota electricity consumption meter?

[thommy6102]

I`ve got an Soyo Inverter 48V without Display. Therfore I choose "esp8266-display-wifi-version-limiter-example.yaml", to flash on my D1 mini. Must I include some code to the "esp8266-display-wifi-version-limiter-example.yaml" file? And if so, how is it done? With other words: How do I have to proceed to insert the code for querying my Tasmota electricity consumption meter into the yaml file?

Thanks for any help.

You did choose the correct configuration example (YAML) if you want to drive the power output of your Soyosource using the RS485 limiter port. If you cannot retrieve the instantaneous power consumption using MQTT you should remove these lines:

  # mqtt subscribe example
  - id: powermeter0
    internal: true
    platform: mqtt_subscribe
    name: "${name} instantaneous power consumption"
    topic: "smartmeter/sensor/groundfloor/obis/1-0:16.7.0/255/value"
    accuracy_decimals: 2
    unit_of_measurement: W
    device_class: power
    filters:
      - throttle_average: 15s

https://github.com/syssi/esphome-soyosource-gtn-virtual-meter/blob/main/esp8266-display-wifi-version-limiter-example.yaml

And add another method to retrieve the instantaneous power consumption f.e. this one:

https://github.com/syssi/esphome-soyosource-gtn-virtual-meter/blob/main/powermeter-sensor-examples/tasmota-http-status-sns.yaml

If you merge/combine both examples into one setup the YAML should look like this:

esp8266-display-wifi-version-limiter-tasmota-sns-example.yaml.txt

Thanks a lot for your very quick help. Ive flashed your merged/combined file.. (Opened it with notepad++ and copied it to my ESPhome) Ive changed the tasmota_status_url to that one what I have.

But I do not see a difference. What Iv e expected was to see the actual power consumption from my powermeter inside the web interface. I dont wanna use MQTT. So, Ididnt configure it. The similar project (0 power consumtion by Bavarian Super Guy is running here since 6 month. Were Im wrong?

BTW: Is there any possibillity to accelarate the compiling/flashing process with ESPhome, inside Home Assistant?

Could you open the tasmota_status_url in a browser and provide the JSON object here? I would like to verify the hierarchy and content.

The short answer is "no". If you compile a ESPHome node a second time without cleaning the build folder it should be pretty fast because most of the parts can be reused.

I used this url: http://192.168.2.56/cm?cmnd=status+10

and it shows me:

StatusSMS: Time: "2023-07-07T09:21:48 SML

This is the expected response (with german keys): https://github.com/syssi/esphome-soyosource-gtn-virtual-meter/blob/main/powermeter-sensor-examples/tasmota-http-status-sns.json

This part of the parser must be adapted:

# from
              - lambda: |-
                  std::string response_data = id(http_request0).get_string();
                  if(!response_data.empty()) {
                    json::parse_json(response_data, [](JsonObject root) {
                      id(powermeter0).publish_state(root["StatusSNS"]["SML"]["Leistung"]);
                    });
                  }

# to
              - lambda: |-
                  std::string response_data = id(http_request0).get_string();
                  if(!response_data.empty()) {
                    json::parse_json(response_data, [](JsonObject root) {
                      id(powermeter0).publish_state(root["StatusSNS"]["SML"]["curr_w"]);
                    });
                  }

Could you provide the SML status response as raw data? I would like to add another powermeter example to the project.

1. https://github.com/syssi/esphome-soyosource-gtn-virtual-meter/pull/144 Sri, I don`t understand.

2. The exchange from "Leistung" to "cur_w" inside the string was it. Now it`s running.

Many thanks for your effort to me and your Hamspirit.

Last question from my side. I`ve often have tp press the F5 button im my Firefox Browser to keep the page up to date. Is it normal?

[syssi]

1. It's just a notification about two new files: https://github.com/syssi/esphome-soyosource-gtn-virtual-meter/pull/144/files
2. Looks good to me!
3. The small website of the web_server component uses a tiny javascript implementation to subscribe to a event stream using websockets to be able to update the sensor measurements instantaneously. A refresh of the page isn't required in general.

[thommy6102]

OK, thanks again for your great job. Problem is fixed now. I`m going to close this issue.

BTW: Im using a "Hitchi IR Reader" connected to Node MCU 8266 with Tasmota. Maybe its helpfull for other users.

May be you would like to transform the device to a ESPHome node some day. This is the required component: https://esphome.io/components/sml.html
