I placed a switch in my room and now I can turn it on in VR to run Calculator on my "NewLaptop" computer via TRIGGERcmd.

It's pretty cool, but it needs work. It's opensource. I downloaded it for free and installed it with SideQuest, but you can also install it from the Meta Quest app store for $5. It reads your devices from your Home Assistant server.

https://immersive-home.org/

Install the "Mosquitto broker" Home Assistant add-on if you don't already have it.

Create a Home Assistant user for Tasmota to log into MQTT using this web page:
http://homeassistant.local:8123/config/users

Connect your ESP32 device to your PC via USB and install Tasmota firmware using this web page:
https://tasmota.github.io/install

Connect it to your wifi, open the Tasmota web interface, and enable MQTT. Point it to your Home Assistant IP address, and input the username and password for the user you just created for it.

In the Tasmota Module configuration, enable IRrecv on GPIO 15:

Add this to your Home Assistant configuration.yaml. This will make the IR receiver(s) available as entities you can select on your automation.

mqtt: 
  sensor:
  - name: "IR Receiver Blue"
    state_topic: "tele/tasmota_778254/RESULT"
    value_template: "{{ value_json.IrReceived.Data }}"
  - name: "IR Receiver White"
    state_topic: "tele/tasmota_47F4CC/RESULT"
    value_template: "{{ value_json.IrReceived.Data }}"

Modify it for your specific tasmota name(s) instead of tasmota_778254 or tasmota_47F4CC. You'll find yours on the MQTT configuration page.

Go to this page and install the blueprint with the IMPORT BLUEPRINT button.
http://homeassistant.local:8123/config/blueprint/dashboard

Click the blueprint and configure your automation with an action for each of the 21 buttons on the IR remote. Notice the automation can use multiple IR receivers if you want.

The IR remotes are cheap enough you can buy a bunch and have them all over:

Optionally, you might also want to run this command in the console to prevent it from losing its config when the power going out and back on too many times:

SetOption65 1

If you prefer a Raspberry Pi solution that uses the same IR remote, check out this post.

EDIT 4/12/25: I've learned that these basic IR receivers work more consistently:
https://www.amazon.com/Vishay-TSOP4838-Infrared-Receiver-Pack/dp/B00UO9VO8O

These work well too:

I've been thinking about how I could allow other parameters. Would you want to create an HA automation that triggers the command, and do you want the properties of the device that triggered the automation to be selectable as command parameters? I think I could build a way to do that.

#!/bin/bash

mkdir -p ~/ha/config
docker run -d \
  --name homeassistant \
  --privileged \
  -e TZ=America/Detroit \
  -v ~/ha/config:/config \
  -v /run/dbus:/run/dbus:ro \
  -p 8123:8123 \
  --rm \
  ghcr.io/home-assistant/home-assistant:stable

This shows my session where I ran it, then confirmed it's running with the docker ps command:

russ@RussHP:~/ha$ cat start.sh
#!/bin/bash

mkdir -p ~/ha/config
docker run -d \
  --name homeassistant \
  --privileged \
  -e TZ=America/Detroit \
  -v ~/ha/config:/config \
  -v /run/dbus:/run/dbus:ro \

After it was running, I was able to access it at http://localhost:8123

You should see this at the top of the page:

import requests

# Home Assistant settings
BASE_URL = "http://(your HA server IP):8123/api"
TOKEN = "(your long-lived HA access token)"

# Headers for authentication
HEADERS = {
    "Authorization": f"Bearer {TOKEN}",
    "Content-Type": "application/json"
}

def toggle_light(entity_id):
    """Toggle a light entity in Home Assistant."""
    url = f"{BASE_URL}/services/light/toggle"
    data = {"entity_id": entity_id}
    
    response = requests.post(url, json=data, headers=HEADERS)
    
    if response.status_code == 200:
        print(f"Successfully toggled {entity_id}.")
    else:
        print(f"Failed to toggle {entity_id}. Status code: {response.status_code}, Response: {response.text}")

# Example usage
if __name__ == "__main__":
    light_entity_id = "switch.laptop_calculator"  # Replace with your entity ID
    toggle_light(light_entity_id)

The above script shows how to flip a switch, including the virtual switches you get from the official TRIGGERcmd integration.
