OTA updates

An ongoing discussion about this feature can be found in #2921open in new window

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

Not all manufacturers make their updates available, below is a (not-complete) list of manufacturer/devices that support it:

  • IKEA TRÅDFRI devices
  • Ubisys devices
  • Some Xiaomi 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

To check wether your specific device supports OTA updates via Zigbee2MQTT, go to the supported devices page, click on your device and look for the OTA updates section.

Automatic checking for available updates

Your zigbee devices can request a firmware update check. Zigbee2MQTT obliges this, and will automatically check if updates are available for your devices.

The update state will be published to zigbee2mqtt/[DEVICE_FRIENDLY_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

To protect privacy it is possible to limit how often third party servers may be contacted. You can set the minimum time that should pass between two firmware update checks, in minutes. The default is 1440 minutes (1 day). Here it is set to check at most every two days:

ota:
    update_check_interval: 2880
1
2

It is also possible to completely ignore these device-initiated requests for updates checks by modifying the configuration.yaml file. In the example below, only manual firmware update checks will be possible:

ota:
    disable_automatic_update_check: true
1
2

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

Manually 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.
