tuya-local

Home Assistant Tuya Local component

The tuya_local component integrates Goldair WiFi-enabled heaters, WiFi-enabled dehumidifiers, WiFi-enabled fans and Kogan WiFi-enabled heaters into Home Assistant, enabling control of setting the following parameters via the UI and the following services:

Climate devices

Goldair GPPH Heaters

• power (on/off)
• mode (Comfort, Eco, Anti-freeze)
• target temperature (5-35 in Comfort mode, 5-21 in Eco mode, in °C)
• power level (via the swing mode setting because no appropriate HA option exists: Auto, 1-5, Stop)

Current temperature is also displayed.

Goldair GPCV Heaters

• power (on/off)
• mode (Low, High)
• target temperature (15-35 in °C)

Current temperature is also displayed.

Goldair GECO Heaters

• power (on/off)
• target temperature (15-35 in °C)

Current temperature is also displayed.

Goldair Dehumidifiers

• power (on/off)
• mode (Normal, Low, High, Dry clothes, Air clean)
• target humidity (30-80%)

Current temperature is displayed, and current humidity is available as a property. The "tank full" state is available via the error attribute, and if you want to you can easily surface this to a top-level entity using a template sensor.

Goldair Fans

• power (on/off)
• mode (Normal, Eco, Sleep)
• fan mode (1-12)
• swing (on/off)

Kogan Heaters

• power (on/off)
• mode (LOW/HIGH)
• target temperature (16-30 in °C)

Current temperature is also displayed.

Additional features

Light (Goldair devices)

• LED display (on/off)

Lock (Goldair heaters and dehumidifiers)

• Child lock (on/off)

Switch devices

**Kogan Energy monitoring Smart Plug

• power (on/off)
• current power consumption (Watts)
• Additional non-standard attributes
  • current current draw (Amps)
  • current voltage (Volts)
  • timer (seconds) [provided as read only]

Warning

Please note, this component has currently only been tested with the Goldair GPPH (inverter), GPDH420 (dehumidifier), and GCPF315 fan, however theoretically it should also work with GECO, GEPH and GPCV heater devices, may work with the GPDH440 dehumidifier and any other Goldair heaters, dehumidifiers or fans based on the Tuya platform.

GPCV support is based on feedback from etamtlosz on Issue #27.

GECO support is based on work in KiLLeRRaT/homeassistant-goldair-climate and the feature set from the online manual for these heaters. GEPH heaters appear to be the same as the GECO270, so may also work with this setting. This heater is almost compatible with the GPCV but without the Low/High mode.

Kogan heater support is tested with the Kogan SmarterHome 1500W Smart Panel Heater. If you have another type of Kogan SmarterHome heater, it may or may not work with the same configuration.

Installation

Installation is via the Home Assistant Community Store (HACS), which is the best place to get third-party integrations for Home Assistant. Once you have HACS set up, simply follow the instructions for adding a custom repository and then the integration will be available to install like any other.

Configuration

You can easily configure your devices using the Integrations UI at Home Assistant > Configuration > Integrations > +. This is the preferred method as things will be unlikely to break as this integration is upgraded. You will need to provide your device's IP address, device ID and local key; the last two can be found using the instructions below.

If you would rather configure using yaml, add the following lines to your configuration.yaml file (but bear in mind that if the configuration options change your configuration may break until you update it to match the changes):

# Example configuration.yaml entry
tuya_local:
  - name: My heater
    host: 1.2.3.4
    device_id: <your device id>
    local_key: <your local key>

Configuration variables

name

    (string) (Required) Any unique name for the device; required because the Tuya API doesn't provide the one you set in the app.

host

    (string) (Required) IP or hostname of the device.

device_id

    (string) (Required) Device ID retrieved as per the instructions below.

local_key

    (string) (Required) Local key retrieved as per the instructions below.

type

    (string) (Optional) The type of Tuya device. auto to automatically detect the device type, or if that doesn't work, select from the available options heater, geco_heater gpcv_heater, dehumidifier, fan, kogan_heater or kogan_switch.

    Default value: auto

climate

    (boolean) (Optional) Whether to surface this appliance as a climate device. (not supported for switches)

    Default value: true

display_light

    (boolean) (Optional) Whether to surface this appliance's LED display control as a light (not supported for Kogan, GECO or GPCV Heaters, or switches).

    Default value: false

child_lock

    (boolean) (Optional) Whether to surface this appliances's child lock as a lock device (not supported for fans or switches).

    Default value: false

switch

    (boolean) (Optional) Whether to surface this device as a switch device (supported only for switches)

Heater gotchas

Goldair GPPH heaters have individual target temperatures for their Comfort and Eco modes, whereas Home Assistant only supports a single target temperature. Therefore, when you're in Comfort mode you will set the Comfort temperature (5-35), and when you're in Eco mode you will set the Eco temperature (5-21), just like you were using the heater's own control panel. Bear this in mind when writing automations that change the operation mode and set a temperature at the same time: you must change the operation mode before setting the new target temperature, otherwise you will set the current thermostat rather than the new one.

When switching to Anti-freeze mode, the heater will set the current power level to 1 as if you had manually chosen it. When you switch back to other modes, you will no longer be in Auto and will have to set it again if this is what you wanted. This could be worked around in code however it would require storing state that may be cleared if HA is restarted and due to this unreliability it's probably best that you just factor it into your automations.

When child lock is enabled, the heater's display will flash with the child lock symbol ([]) whenever you change something in HA. This can be confusing because it's the same behaviour as when you try to change something via the heater's own control panel and the change is rejected due to being locked, however rest assured that the changes are taking effect.

Fan gotchas

In my experience, fans can be a bit flaky. If they become unresponsive, give them about 60 seconds to wake up again.

Finding your device ID and local key

You can find these keys the same way as you would for any Tuya local integration. You'll need the Goldair app or the Tuya Tuya Smart app (the Goldair app is just a rebranded Tuya app), then follow these instructions.

Next steps

1. The devices need to be generalized so a new subdirectory with source code is not needed to add a new device. Instead, device descriptors should be in a yaml file, which is referenced by the config.
2. Support for non-climate devices needs to be added. For starters, I have some Kogan Power Monitoring Plugs that I haven't yet taken out of the box and converted to ESPHome, but this will probably need input from other users.
3. This component needs specs! Once they're written I'm considering submitting it to the HA team for inclusion in standard installations. Please report any issues and feel free to raise pull requests.

None of this would have been possible without some foundational discovery work to get me started:

• nikrolls's homeassistant-goldair-climate was the starting point for expanding to non-Goldair devices as well
• TarxBoy's investigation using codetheweb/tuyapi to figure out the correlation of the cryptic DPS states
• sean6541's tuya-homeassistant library giving an example of integrating Tuya devices with Home Assistant
