IR Remote

This article will show you the process of setting up the IR remote control.

All devices from Robonomics can be purchased on the official website.

Step 1 — Flashing

All devices from Robonomics come pre-flashed out of the box. However, since all devices are development kits, the instructions will cover the option of flashing the device from scratch. If you do not wish to do this now, proceed to Step 2 - Access Point.

Take the device from the box and connect it to the computer. Then go to the website webflasher.robonomics.network. This is the web flasher.

Note! Web flasher is working only with Google Chrome or Microsoft Edge browser.

In “Firmware” drop-box choose “IR REMOTE” option and next in “SELECT CHIP” choose “ESP32”. Press “CONNECT” button.
A popup window will appear where you should select the serial port to which the device is connected (usually it’s /ttyUSB0). Then choose “INSTALL IR-REMOTE_EN”.
On next window, you can make CLEAR INSTALLATION by check ERASE DEVICE. Press Next and then Install. Wait until firmware to upload to the IR controller.

After finishing the installation process Wi-Fi configuration popup will appear. There you have options:

1. You can provide Wi-Fi credentials, skip Step 2 - Access Point and go to Step 3 - Configuration.

After setting up Wi-Fi you can visit device via VISIT DEVICE button. Later you can visit device via it’s IP address in the network. To find it you can use Fing mobile app or
nmap CLI tool.

2. Or disconnect the device from the computer and connect it to the power supply. IR Remote will start and create a Wi-Fi hotspot. To connect the IR Remote to your home Wi-Fi network through a hotspot, follow the instructions in Step 2.

Step 2 — Access Point

If you take IR Remote from the box and connect it to the power supply, it will create hotspot with name “tasmota-XXXXXXX”. Connect to it. Configuration window should open. If not, open web-browser and go to 192.168.4.1 page.

Provide Wi-Fi credentials. After that the IR Remote will connect to Wi-Fi network. Check the device via it’s IP address in the network. To find it you can use Fing mobile app or
nmap CLI tool.

Step 3 — Configuration

Go to “Configuration”->“Configure other”. In “Template” string insert next:

{"NAME":"Robonomics IR remote","GPIO":[1,1,1,1,1056,1088,1,1,1,1,1,1,1,1,1,1,0,1,1,1,0,1,1,1,0,0,0,0,1,1,1,1,1,0,0,1],"FLAG":0,"BASE":1}

Verify that checkbox “Activate” and “MQTT Enable” is enabled. If not, enable it and press Save button.

Return to “Main Menu” and go to “Configuration” -> “Configure MQTT”.
Provide your MQTT credentials here:

That’s all with ESP for now. The next step is to install the Home Assistant integration.

Step 4 — Integration Setup

This article assumes, that you have Home Assistant and HACS. Go to HACS and add custom repository.

To do this, press three dots in upper right corner, choose CUSTOM REPOSITORIES
and insert this URL: https://github.com/hristo-atanasov/Tasmota-IRHVAC. in Category choose “Integration”. After that find it in search and install it. Don’t forget to restart Home Assistant after that.

Open logs of the IR remote. To do this go to proper local URL, or open again webflasher.robonomics.network and choose “Tasmota IR” and “ESP32”. Press “Connect” and choose port.
Press VISIT DEVICE, and you will see the device main page. Go to “Consoles” -> “console”.

Point your IR remote control (e.g. from an air conditioner) to the Robonomics IR Remote and press buttons on the remote. You will get next log in the console:

10:08:06.925 MQT: tele/tasmota_F6CF74/RESULT = {"IrReceived":{"Protocol":"MITSUBISHI112","Bits":112,"Data":"0x23CB260100A003060D00000000CB","Repeat":0,"IRHVAC":{"Vendor":"MITSUBISHI112","Model":-1,"Mode":"Cool","Power":"Off","Celsius":"On","Temp":25,"FanSpeed":"Medium","SwingV":"Highest","SwingH":"Auto","Quiet":"Off","Turbo":"Off","Econo":"Off","Light":"Off","Filter":"Off","Clean":"Off","Beep":"Off","Sleep":-1}}}

You need information from IRHVAC topic.

Open configuration.yaml file of our Home Assistant instance and insert the following:

Save configuration.yaml and restart Home Assistant.
After restarting you can add in UI a new thermostat card and select the newly integrated device.

If you have problem with GUI mode, switch to “CODE EDITOR” and write next:

type: thermostat
entity: climate.<your climate name>

All devices from Robonomics can be purchased on the official website.
