This is a Home Assistant integration to support devices running Tuya firmware without going via the Tuya cloud. Devices are supported over WiFi, limited support for devices connected via hubs is available.

Note that many Tuya devices seem to support only one local connection. If you have connection issues when using this integration, ensure that other integrations offering local Tuya connections are not configured to use the same device, mobile applications on devices on the local network are closed, and no other software is trying to connect locally to your Tuya devices.

Using this integration does not stop your devices from sending status to the Tuya cloud, so this should not be seen as a security measure, rather it improves speed and reliability by using local connections, and may unlock some features of your device, or even unlock whole devices, that are not supported by the Tuya cloud API.

A similar but unrelated integration is rospogrigio/localtuya, if your device is not supported by this integration, you may find it easier to set up using that, or another more recent fork, as an alternative.

Installation

Installation is easiest 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 click the button below (requires My Homeassistant configured) or follow the instructions for adding a custom repository and then the integration will be available to install like any other.

Configuration

After installing, you can easily configure your devices using the Integrations configuration UI. Go to Settings / Devices & Services and press the Add Integration button, or click the shortcut button below (requires My Homeassistant configured).

Choose your configuration path

There are two options for configuring a device:

• You can login to Tuya cloud with the Tuya or SmartLife app and retrieve a list of devices and the necessary local connection data.
• You can provide all the necessary information manually as per the instructions in DEVICES_DETAILS.md.

The first choice essentially automates all the manual steps of the second and without needing to create a Tuya IOT developer account. This is especially important now that Tuya has started time limiting access to a key data access capability in the IOT developer portal to only a month with the ability to refresh the trial of that only every 6 months.

The cloud assisted choice will guide you through authenticating, choosing a device to add from the list of devices associated with your Tuya account, locate the device on your local subnet and then drop you into Stage One with fully populated data necessary to move forward to Stage Two.

The Tuya authentication token expires after a small number of hours and so is not saved by the integration. But, as long as you don't restart Home Assistant, this allows you to add multiple devices one after another only needing to authenticate once for the first one.

Stage One

The first stage of configuration is to provide the information needed to connect to the device.

When using the cloud assisted config, the device id and local key will be pre-filled from the cloud, and the IP address will also be filled if local discovery is not blocked by other integrations or a complex network setup. Otherwise, see DEVICE_DETAILS.md for instructions on how to find the info.

host

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

device_id

    (string) (Required) Device ID retrieved

local_key

    (string) (Required) Local key retrieved

Note that each time you pair the device, the local key changes, so if you obtained the local key using the instructions below, then re-paired with your manufacturer's app, then the key will have changed already.

protocol_version

    (string or float) (Required) Valid options are "auto", 3.1, 3.2, 3.3, 3.4, 3.5, 3.22. If you aren't sure, choose "auto", but some 3.2, 3.22 and maybe 3.4 devices may be misdetected as 3.3 (or vice-versa), so if your device does not seem to respond to commands reliably, try selecting between those protocol versions. Protocol 3.22 is a special case, that enables tinytuya's "device22" detection with protocol 3.3. Previously we let tinytuya auto-detect this, but it was found to sometimes misdetect genuine 3.3 devices as device22 which stops them receiving updates, so an explicit version was added to enable the device22 detection.

At the end of this step, an attempt is made to connect to the device and see if it returns any data. For tuya protocol version 3.1 devices, the local key is only used for sending commands to the device, so if your local key is incorrect the setup will appear to work, and you will not see any problems until you try to control your device. For more recent Tuya protocol versions, the local key is used to decrypt received data as well, so an incorrect key will be detected at this step and cause an immediate failure.

Stage Two

The second stage of configuration is to select which device you are connecting. The list of devices offered will be limited to devices which appear to be at least a partial match to the data returned by the device.

type

    (string) (Optional) The type of Tuya device. Select from the available options.

The list presented is filtered to exclude devices that definitely do not match among the 1000+ supported devices. If a device config you expected is not shown, you may have a different firmware version, so the best way to report this is as a new device.

If you pick the wrong type, you will need to delete the device and set it up again. This is because different types of devices create different entities, so changing the device type without deleting everything is not advisable.

Stage Three

The final stage is to choose a name for the device in Home Assistant.

If you have multiple devices of the same type, you may want to change the name to make it easier to distinguish them.

name

    (string) (Required) Any unique name for the device. This will be used as the base for the entity names in Home Assistant.

Device support

A list of currently supported devices can be found in the DEVICES.md file.

Note that devices sometimes get firmware upgrades, or incompatible versions are sold under the same model name, so it is possible that the device will not work despite being listed.

Battery powered devices such as door and window sensors, smoke alarms etc which do not use a hub are not possible to support locally, due to the power management that they need to do to get acceptable battery life. In some cases that may also apply when a device that can be either battery or USB powered is plugged into USB. If you cannot gather Warning level logs with dps listed when attempting to set it up, then it will likely not work with this integration.

Hubs are currently supported, but with limitations. Each connection to a sub device uses a separate network connection, but like other Tuya devices, hubs are usually limited in the number of connections they can handle, with typical limits being 1 or 3, depending on the specific Tuya module they are using. This severely limits the number of sub devices that can be connected through this integration.

Sub devices should be added using the device_id, address and local_key of the hub they are attached to, and the node_id of the sub-device. If there is no node_id listed, try using the uuid instead.

Tuya Zigbee devices are usually standard zigbee devices, so as an alternative to this integration with a Tuya hub, you can use a supported Zigbee USB stick or Wifi hub with ZHA or Zigbee2MQTT.

Some Tuya Bluetooth devices can be supported directly by the tuya_ble integration.

Some Tuya hubs now support Matter over WiFi, and this can be used as an alternative to this integration for connecting the hub and sub-devices to Home Assistant. Other limitations will apply to this, so you might want to try both, and only use this integration for devices that are not working properly over Matter.

Tuya IR hubs that expose general IR remotes as sub devices usually expose them as one way devices (send only) except in learning mode, if they expose them at all locally. In general, Tuya IR hubs are only useful for HA's built in IR support, not for any Tuya features such as their predefined (cloud only) device database, or climate device simulation.

Contributing

Documentation on building a device configuration file is in /custom_components/tuya_local/devices/README.md

If your device is not listed, you can find the information required to add a configuration for it in the following locations:

1. When attempting to add the device, if it is not supported, you will either get a message saying the device cannot be recognised at all, or you will be offered a list of devices that are partial matches. You can cancel the process at this point, and look in the Home Assistant log - there should be a message there containing the current data points (dps) returned by the device.
2. If you have signed up for iot.tuya.com, you should have access to the API Explorer under "Cloud". Under "Device Control" there is a function called "Query Things Data Model", which returns the dp id in addition to range information that is needed for integer and enum data types.

If you file an issue to request support for a new device, please include the following information:

1. Logs from this integration showing the LOCAL DPS actually received from the device.
2. Identification of the device, such as model and brand name.
3. As much information on the datapoints you can gather using the above methods.
4. If manuals or webpages are available online, links to those help understand how to interpret the technical info above - even if they are not in English automatic translations can help, or information in them may help to identify identical devices sold under other brands in other countries that do have English or more detailed information available.

If you submit a pull request, please understand that the config file naming and details of the configuration may get modified before release - for example if your name was too generic, I may rename it to a more specific name, or conversely if the device appears to be generic and sold under many brands, I may change the brand specific name to something more general. So it may be necessary to remove and re-add your device once it has been integrated into a release.

Offline operation issues

Many Tuya devices will stop responding if unable to connect to the Tuya servers for an extended period. Reportedly, some devices act better offline if DNS as well as TCP connections is blocked.

General issues

Many Tuya devices do not handle multiple commands sent in quick succession. Some will reboot, possibly changing state in the process, others will go offline for 30s to a few minutes if you overload them. There is some rate limiting to try to avoid this, but it is not sufficient for some devices, and may not work across entities where you are sending commands to multiple entities on the same device. The rate limiting also combines commands, which not all devices can handle. If you are sending commands from an automation, it is best to add delays between commands - if your automation is for multiple devices, it might be enough to send commands to other devices first before coming back to send a second command to the first one, or you may still need a delay after that. The exact timing depends on the device, so you may need to experiment to find the minimum delay that gives reliable results.

Most devices can handle multiple commands in a single message, so for entity platforms that support it (eg climate set_temperature can include presets, lights pretty much everything is set through turn_on) multiple settings are sent at once. But some devices do not like this and require all commands to set only a single dp at a time, so you may need to experiment with your automations to see whether a single command or multiple commands (with delays, see above) work best with your devices.

When adding devices, some devices that are detected as protocol version 3.3 at first require version 3.2 to work correctly. Either they cannot be detected, or work as read-only if the pprotocol is set to 3.3.

Connecting to devices via hubs

If your device connects via a hub (eg. battery powered water timers) you have to provide the following info when adding a new device:

• Device id (uuid): this is the hub's device id
• IP address or hostname: the hub's IP address or hostname
• Local key: the hub's local key
• Sub device id: the actual device you want to control's node_id. Note this node_id differs from the device id, you can find it with tinytuya as described below.

Secure locks

Many locks are designed with basic security controls to make remote unlocking more difficult. This integration supports the standard BLE lock model from Tuya which uses a pair of dps (60: remote_no_pd_seykey, 61: remote_no_dp_key) to share a key between the app and the lock during the pairing phase. If you have access to the Tuya developer portal, you can eavesdrop on the second of these messages when the app is used to unlock the lock remotely. If you capture the value sent by the app, then you can decode it using a base64 decoder such as https://base64decode.org. The format has 4 bytes of binary data, followed by an 8 digit ASCII numeric code, followed by 3 or 4 more bytes of binary data.

The 8 digit numeric code from the first app that was paired should work for unlocking the lock.

Although this is documented in the BLE lock documentation from Tuya, Zigbee and WiFi locks often use the same naming for datapoints, which may be compatible with this scheme.

IR/RF blasters

Tuya IR and RF blasters are exposed as remote entities and support learning and sending commands via the standard Home Assistant remote services. IR blasters are also exposed as general infrared emitters, and learned commands can be sent to other infrared emitters using the tuya-local specific "Send Learned IR command" service.

Learning commands

Use the remote.learn_command service with:

• command: the name to store the command under (e.g. power)
• device: a name for the appliance being controlled (e.g. TV)
• command_type: set to rf for RF remotes, omit or leave blank for IR

The integration will put the blaster into learning mode and wait up to 30 seconds for you to press a button on the original remote. The learned code is stored persistently and survives restarts.

Sending commands

Using the infrared platform, you can send known IR commands using other HA integrations, including HAIR, a custom integration for learning remote commands via an ESPHome receiver and sending them to any supported infrared emitter.

To send learned commands using the same remote entity, you use the remote.send_command service with the same command and device values used when learning. You can also send known Tuya codes directly without learning first:

• IR inline code: prefix with b64: followed by the base64-encoded IR code
• RF inline code: prefix with rf: followed by the base64-encoded RF code

There is also a special send_learned_ir_command service for sending commands learned by the remote entity to any infrared emitter (including non-Tuya ones). To use this, you must specify the remote entity the learned command was saved with, the target infrared emitter entity, and the command and optional device the command was saved as.

UI

If you would like to expose the learnt commands as buttons in the user interface you might want to take a look at the Remote buttons integration, which is compatible with Tuya Local.

Pet feeders

Many pet feeders expose an encoded Meal plan setting via a text entity. By default this is disabled, but you can enable it under the Device settings in HA. When enabled many pet feeders share the same underlying format, which is supported by the FrederikM97/mealplan-card custom card.

Contributing

Beyond contributing device configs, here are some areas that could benefit from more hands:

1. Unit tests. This integration is mostly unit-tested thanks to the upstream project, but there are a few more to complete. Focus on unit tests is on python code, the current coverage is summarised in reports on github, but to get full coverage details you can run the tests yourself.
2. Once unit tests are complete, the next task is to properly evaluate against the Home Assistant quality scale.
3. Discovery. Local discovery is currently limited to finding the IP address in the cloud assisted config. Performing discovery in background would allow notifications to be raised when new devices are noticed on the network, and would provide a productKey for the manual config method to use when matching device configs.
