OTA updates #

An ongoing discussion about this feature can be found here: #2921

This feature allows to update your Zigbee devices over-the-air.

Not all manufacturers make their updates available, therefore only the following devices support it:

• IKEA TRÅDFRI devices
• Ubysis devices
• Salus SP600 Smart plug
• Osram/Ledvance devices (not every firmware is made available by them, in case not you will see the following exception in the log No image available for ...)
• Philips Hue devices (not every firmware is made available by them, in case not you will see the following exception in the log No image available for ...)
• Jung ZLLxx5004M, Jung ZLLHS4 and Gira 2435-10 Gira does unfortunately not seem to offer firmware updates for their wall transmitter 2430-100 (which is very similar to the Jung ZLLxx5004M) and the update file for the Jung wall transmitter does not work for Gira (probably because the Gira wall transmitter only has 6 buttons instead of 8 on the Jung).
• Sengled devices

Zigbee2MQTT automatically checks if updates are available for your devices.

The update state will be published to zigbee2mqtt/[DEVICE_FRIENLDY_NAME], example payload: {"update": {"state": "available"}}. The possible states are:

• available: an update is available for this device
• updating: update is in progress. During this the progress in % and remaining time in seconds is also added to the payload, example: {"update": {"state": "updating","progress":13.37,"remaining": 219}}.
• idle: no update available/in progress

NOTE: there is also a property update_available which is deprecated.

Check if an update is available #

To check if an update is available for your device send a message to zigbee2mqtt/bridge/request/device/ota_update/check with payload {"id": "deviceID"} or deviceID where deviceID can be the ieee_address or friendly_name of the device. Example; request: {"id": "my_remote"} or my_remote, response: {"data":{"id": "my_remote","updateAvailable":true},"status":"ok"}.

Update to latest firmware #

Once an update is available you can update it by sending to zigbee2mqtt/bridge/request/device/ota_update/update with payload {"id": "deviceID"} or deviceID where deviceID can be the ieee_address or friendly_name of the device, example request: {"id": "my_remote"} or my_remote. Once the update is completed a response is send, example response: {"data":{"id": "my_remote","from":{"software_build_id":1,"date_code":"20190101"},"to":{"software_build_id":2,"date_code":"20190102"}},"status":"ok"}.

An update typically takes +- 10 minutes. While a device is updating a lot of traffic is generated on the network, therefore it is not recommend to execute multiple updates at the same time.

Using the IKEA TRADFRI test server #

The current published firmwares (as of 2020-12-09) by IKEA are corrupted which makes the devices reject the update. The firmwares published on the IKEA test server are not corrupted. You can instruct Zigbee2MQTT to use the test server by adding the following to your configuration.yaml.

WARNING: Use at your own risk!

Troubleshooting #

• Device didn't respond to OTA request or Update failed with reason: 'aborted by device': try restarting the device by disconnecting the power/battery for a few seconds and try again.
• For battery powered devices make sure that the battery is 70%+ as OTA updating is very power consuming.
