Dreo Smart Device Integration for Home Assistant

HomeAssistant integration for Dreo brand smart devices. Currently supports some models of Tower Fans, Air Circulators and Space Heaters.

You can purchase these devices from Amazon: Dreo Fans on Amazon

This integration is based on the engineering that Gavin Zyonse did for the HomeBridge integration here: https://github.com/zyonse/homebridge-dreo.

This documentation is intended to be accurate for the branch/tag it's in. If you are installing a specific version (including latest) of the integration, please change current viewing tag in GitHub to see the matching documentation.

Heaters are modeled as climate devices, which enables the ability to put a thermostat control for the heater into your HA dashboards. Some examples are shown below.

Oscillation is now supported, but shown under "swing mode" since this is how the climate device models that. Note that for all heaters, to satisfy UL listings the remote control is disabled if it has not been used for 24 hours, which will then necessitate a quick tap on the WiFi button on the physical heater to resume the ability to control the device remotely via either the Dreo app or this HA integration.

Installation

HACS (Recommended)

Dreo is now part of the default HACS store. If you're not interested in development branches this is the easiest way to install.

Installing Dreo Smart Device Integration

1. Open HACS
2. Click Integrations
3. Search Dreo
4. Click the Dreo Smart Device Integration and install

Manually

Copy the dreo directory into your /config/custom_components directory, then restart your HomeAssistant Core.

Initial Configuration

Important

If you used the very early version of this that required editing configuration.yaml, you will need to do a one-time reconfiguration. Delete the configuration entries you added and then go through the configuration flow within HomeAssistant.

1. In HA, open Settings
2. Click Devices & services
3. Click Add integration (blue button at the bottom right of the screen)
4. Search Dreo and select it
5. Enter your Dreo username & password (same login you use on the Dreo app)

Once the Dreo app has been installed,

Options

This plugin supports configuration from the HomeAssistant UX. The following options are available.

Option	Description	Default
Auto-Reconnect WebSocket	Should the integration try to reconnect if the websocket connection fails. This should not need to be unchecked, but there have been occasional reports of crashes and we think this may be the cause.	True

Note that at present you need to restart HA when you change an option for it to take effect.

Debugging

Use the Diagnostics feature in HomeAssistant to get diagnostics from the integration. Sensitive info should be redacted automatically.

In your configuration.yaml file, add this:

logger:
    logs:
        dreo: debug
        pydreo: debug

Now restart HomeAssistant. Perform the actions needed to generate some debugging info.

Download the full logs

1. In HA, open Settings
2. Click System
3. Click Logs
4. Click Download full log

Download diagnostics (.json file)

1. In HA, open Settings
2. Click Device & services
3. Click Dreo
4. Click on the three-dot hamburger menu (next to Configure) and click Download diagnostics.

Enable WebSocket debugging

In some cases, you may need to enable WebSocket debugging. You can do that by adding the following to your configuration.yaml file.

logger:
    logs:
        homeassistant.components.websocket_api: debug

Adding New Fans

Don't see your model listed above? Create an issue and I'll add it.

Please make sure to include:

• Model - in the format above
• Number of speeds the fan supports (not including "off")
• Does the fan support oscillating?
• What preset modes are supported?
• Is temperature supported?

Depending on answers, I may reach out and need you to pull some debug logs.

Debug Logs for New Fans

1. Enable debugging
2. Go to the Dreo app on your mobile device and perform the various commands you want to be able to use in HA. Dreo servers will send updates to the WebSocket that the integration is listening on.
3. Go look at the logs, you should see something like the below. Create an issue and include the lines related to pydreo, the diagnostics json file, and if possible, what actions you performed in the app.

To Do

This is my first HA plugin and a bit slow going; bunch of stuff left to do:
