[NonNASA] Outdoor Temperature - Home Assistant Sensor Request

[Goaheadz]

Since there is already a message containing the outdoor temperature, I think making this as a HA sensor, would be handy for automation's.
This is the message I get:

[W] | [samsung_ac:493] | MSG: {src:c8;dst:00;cmd:c0;commandC0:{ou_operation_mode:88; ou_4way_valve:0; ou_hot_gas_bypass:0; ou_compressor:0; ou_ac_fan:0; ou_outdoor_temp[°C]:13; ou_discharge_temp[°C]:11; ou_condenser_mid_temp[°C]:12}}

Let me know what can I do, to make this possible.

Help needed :)

Thx

Beside de temperature, there is also the voltage and amperage being draw by the outdoor machine.
Since power from all splitters are connected to the outdoor, we could also use this information as sensors for consuption log and display.

like adding a new power draw like aqs in picture:

I added that for NASA protocol in my pull request. IDK how it can be implemented for non-nasa protocol

[Goaheadz]

IDK either, but if its possible to extract temperature from sensors in splitters, it should be straigth forward to do the same for sensor in the outdoor machine.

@lanwin may be the saviour :)

Yes its my plan to add that too. But did not expect it soon. My desk is currently overflowing with other work.

No news regarding this?

Hello @Goaheadz,

I appreciate your efforts and interest in enhancing the project. Since I recently took over the project maintenance, I’m eager to help but need a bit more clarity on the Non-NASA protocol as my experience with it is limited.

From what I understand, you’re looking to add sensors for outdoor temperature and possibly for voltage and current measurements to track energy consumption. Is that correct?

To assist you effectively, it would be very helpful if you could provide the following:

Your Current YAML Configuration: This will give me a clear picture of how your ESPHome setup is structured and how the integration is currently working.
Relevant Log Entries: Please share a few lines from your log that contain the message data for outdoor temperature, voltage, and current, so I can see the exact format and structure.
Current Sensor Data from Your ESP Device: Any screenshots or JSON outputs from your ESP device showing the current sensor values would be helpful.
With this information, I can better understand your requirements and work towards implementing a solution. Looking forward to collaborating with you on this!

Best regards,
Ömer Faruk ARAN

Still no luck. Here's the log again.

The error you encountered might be due to the ESPHome source not being updated. To fix this, try adding refresh: 0s to the external_components configuration, which forces ESPHome to pull the latest source every time. Here’s an example:

external_components:
  - source: github://omerfaruk-aran/esphome_samsung_hvac_bus@add-outdoor-sensors 
    components: [samsung_ac]
    refresh: 0s

This will ensure that the latest code version is used, preventing errors caused by outdated cached versions.

That helped install the code but unfortunately, the sensor is unknown in Home Assistant. Yaml and Log attached. Thank you for taking the time to do this. I am off to bed for the night now. Can continue testing tomorrow.

Good night! We’ve made some improvements in the Samsung AC component related to processing the outdoor temperature. Could you please check it again and let us know if the issue is resolved?

[Jkirjo]

That outdoor unit reported outside temp would be nice addition in generally. Most likely it is also available in data stream. I'm also interested in, what unit reporting about defrost cycles. In winter time that could be worth of to know.

Hi Aran,

Thank you so much for all the time you put into this.

As soon as I get home (later in the day) I will also provide some log files and yaml (currently the AC breaker is OFF), and try the new sensor.

devices:
- address: "c8" # Outdoor device address
outdoor_temperature:
name: "Outdoor temperature"

Adding inverter_power[W] sensor, will also allow us, to create a Energy sensor in Home Assistant and control consumption and costs per outdoor unit.

Hi @Goaheadz, @tech2urdoor,

Thank you for the feedback. I have updated the setup and here's an example of how to update your yaml configuration:

1. Update the external_components section:

external_components:
  - source: github://omerfaruk-aran/esphome_samsung_hvac_bus@add-outdoor-sensors 
    components: [samsung_ac]
    refresh: 0s

1. Add the new sensors to your devices:

devices:
  - address: "c8" # Outdoor device address
    outdoor_temperature: 
      name: "Outdoor temperature"

    outdoor_instantaneous_power:
      name: "Outdoor Instantaneous Power"

    outdoor_cumulative_energy:
      name: "Outdoor Cumulative Energy"

    outdoor_current:
      name: "Outdoor Current"

    outdoor_voltage:
      name: "Outdoor Voltage"

After updating this configuration, please build and flash your ESP device. Let me know if you encounter any issues or need further assistance.
