# ArgoClima Binding

The binding provides support for ArgoClima (opens new window) Wi-Fi-enabled air conditioning devices which use Argo Web APP for control. Refer to Argo Web APP details section for an example.

IMPORTANT: The same vendor also manufactures HVAC devices supported by a phone application (opens new window).

These devices are using a different protocol and are not supported by this binding. There are good chances these will be supported by the Gree (opens new window) binding, though!

The binding supports all HVAC remote functions (including built-in schedule and settings) except for iFeel (room) temperature which is not supported by the Argo remote protocol and has to be sent via infrared. The binding can operate in local, remote and hybrid modes. Refer to Connection Modes for more details.

See also Argo protocol details to find out more about how the device operates.

# Supported Things

  • remote: Represents a HVAC device which is controlled remotely - through vendor's web application
  • local: Represents a locally available device, which openHAB interacts with directly (or indirectly, through a stub server). Refer to Connection Modes for more details.

The binding has been primarily developed and tested using Ulisse 13 DCI ECO Wi-Fi (opens new window) device.

# Discovery

The binding does not support device auto-discovery (as the devices don't announce themselves locally).

  • Note it is technically possible for the advanced mode with API stub to discover devices, but as it requires manual firewall reconfiguration, it won't be an "auto" anyway so was not implemented.

# Connection Modes

# Basic Modes

These modes assume the HVAC device is connected directly to the Internet. This is the default (vendor-recommended) configuration which does not require any special network-level changes. There are security considerations when using these modes, though.

# Basic: Local connection

The device is locally available through the LAN. openHAB sends commands directly (and polls for status). Basic local connection diagram

# Basic: Remote connection

The device may not be locally available through the LAN (or the user wants silent/no-beep behavior). openHAB sends commands to a remote vendor's service (and polls it for device status), while the device also talks to the same service and eventually learns the updates. Commands are delayed in this mode. Basic remote connection diagram

# Advanced Modes

In these modes, the HVAC traffic which is originally targeted towards vendor's servers is rerouted on the network layer, and flows to openHAB instead. This is possible as the device does use plain HTTP (no TLS, certificate pinning etc.)

The following nftables snippet provides an example rule redirecting traffic to 31.14.128.210 (Argo server) to a local openHAB instance listening at 192.168.0.15:8239. Please note this is not a complete configuration, and an actual secure configuration requires a few more rules and network setup.

table inet fw4 {
    (...)
    chain dstnat_iot {
        ip daddr 31.14.128.210 tcp dport 1-8000 counter packets 2593 bytes 114092 dnat ip to 192.168.0.15:8239 comment "!fw4: Argo 2 lan"
    }
    (...)
}

For example, if your home router is based on OpenWrt (opens new window) LuCI interface, a graphical representation of the forwarding rule might look similar to the below. Argo traffic forwarding rule in OpenWrt LuCI

Please note this forwarding rule would need to be accompanied with other traffic rules (and separate WLAN/SSID) for the device (this configuration is not covered here - refer to your network equipment's manual for more).

# Advanced: Local connection with pass-through proxy

In this mode openHAB is acting as an almost transparent proxy, and does a pass-through of device-side messages and remote-side responses (a man-in-the-middle). This allows to have the device fully controllable via openHAB as well as vendor's application (at the expense of security!). Possible other use of this mode is for firmware update or ad-hoc controlling some settings which are not easily accessible via openHAB.

IMPORTANT: Most of the time, openHAB serves as a fully transparent proxy, not interfering with the traffic, except for cases when cloud has no updates for the device while openHAB has a command pending send to the device. In such case, the binding injects it into the communication flow as-if it was cloud-issued!

Advanced local connection diagram: REMOTE_API_PROXY mode

In this mode openHAB is simulating vendor's server (which is out of the picture). The HVAC is functioning fully locally. This is the recommended mode for maximum security.

Advanced local connection diagram: REMOTE_API_STUB mode

# Argo protocol details

The HVAC device accepts multiple command in one request (similarly to how the remote control works). Dual APIs (local and remote) are exposed:

  • The local API uses direct HTTP communication (all requests are HTTP GET) and polling for getting the device state. Sending any command through this interface effects an immediate change, and audible confirmation (beep).
  • The remote API involves the device periodically (for example, every minute) reaching out to manufacturer's server, and getting any withstanding commands. Commands sent through this interface will be delayed, and not yield an audible confirmation (no beep).

IMPORTANT: The Argo HVAC device has to be connected to Wi-Fi and communicating with a vendor (or vendor-like) server for either of its APIs to work. This is true even if the device is desired to be controlled via local APIs only!

A NOTE ON SECURITY: The device protocol is plain HTTP (no TLS), and it transmits all the device secrets to the cloud service in cleartext (that includes device password as well as your Wi-Fi password!)

Hence, security-savvy users may choose to not only connect it to a dedicated IOT-specific Wi-Fi network, but also deny its Internet access (ex. to prevent a malicious firmware update converting it to a network backdoor). While the device needs to communicate with a protocol-compatible server to work, this binding provides a convenient simulated server exactly for this purpose! Its use requires a specialized forwarding rules set-up on the home router, hence is only recommended to advanced users, though. Refer to Connection Modes for more details.

# Room temperature support

The Argo APIs support all functionalities of the device's remote, and two-way communication, except for room temperature (iFeel) provided from external sensor (the device's remote control). Its value is read-only in the API protocol.

While using the temperature sensor built-in into the device is sufficient for most cases, for certain scenarios it may be desired to be able to set the room temperature from openHAB (for example: to have multi-sensor aggregate temperature display on the built-in HVAC display).

Since the iFeel temperature updates have to be sent via infrared, there are two notable options to consider:

  • Use the original remote: As long as the remote control is pointing towards the HVAC and A/C status on the remote is ON (with iFeel option enabled), it will periodically beam current temperature (which the HVAC will accept if its iFeel option is ON, which can be configured through the binding).

  • Use openHAB-controlled (custom) IR Blaster:

    The Argo protocol is fully supported by the IRremoteESP8266 (opens new window) library, and Tasmota (opens new window). Hence, any Tasmota-IR (opens new window)-compatible device would be able to send iFeel data to the HVAC (and the device itself can be controlled via openHAB's MQTT Binding (opens new window)).

    For example, (by default) the following command sent to cmnd/<tasmota_dev_id>/irhvac channel does send the iFeel temperature.

    // Hint: You may use JINJA transform to fill the room temperature (in Celsius) from a channel.
    //       The status of IR command execution is available through [stat/<tasmota_dev_id>/RESULT] channel
    { "Vendor": "Argo", "Model": "WREM3", "Command": "iFeel Report", "SensorTemp": <the_room_temperature_value> }
    

# Argo Web APP details

The supported devices will typically have a web interface similar to the one shown on the image below. Argo Web APP

For example, the original web application for Ulisse 13 DCI ECO air conditioner is available through http://31.14.128.210/UI/WEBAPP/webapp.php?logo=Argo (opens new window) link, as referenced in the manual (opens new window).
