  • You can now hide offline devices from the Home page device list for a cleaner, more focused view.
  1. Data Visualization Enhancements
  • Temperature and humidity graphs now support minute-level data for more detailed insights.

Bug Fixes

  1. Fixed an issue where scene notifications were not received via CUBE CAST during remote access.

  2. Fixed compatibility issues with Tuya TS0001 Fingerbot.

  3. Fixed Matter Bridge issues:

  • Fixed an issue where the Matter Bridge repeatedly went offline.
  • Fixed a problem where adding more than 10 devices prevented newly added devices from being synchronized through Matter Bridge.
  • Fixed an issue where the Matter Fabric displayed as empty.
  • Fixed an issue where deleting a device from CUBE did not correctly remove the corresponding device from the third-party Matter platform.
  1. Fixed SONOFF TRVZB issues:
  • Fixed an issue where Boost Mode and Temp. Override Mode failed to execute correctly.
  • Fixed an issue where scene actions incorrectly allowed selecting Temp. Override Mode.
  • Fixed an issue where adjusting the Boost Time while in Boost Mode caused inconsistent or incorrect timing.
  • Fixed a bug where minute-level data of temperature and humidity graphs could not be properly displayed.
  • Fixed an issue where the target temperature displayed in CAST exceeded the allowed range.
  • Fixed an issue where the TRV’s target temperature for Boost/Temp. Override Mode could not be synchronized or displayed correctly.

You did a good job but there are also errors. I don’t see the SNZB-02D that I shared to my ewelink account through matter in ihos. iHost claims that it share and ewelink won’t show them.

In a recent firmware update for TRVZB a ‘Boost’ function was introduced that increases the Target Temperature to fixed 35 deg C for a user selected (in device properties) period of 1- 180 minutes.

TRVZB can only be set into ‘Boost’ from the device’s eWeLink cube card and from Automatic or Manual Tap to Run scenes.

When TRVZB is in ‘Boost’ the valve opening % will only be the opening % set by the user in device properties. If a valve is set to open to 10% on ‘Heating’ it will open to only 10% when ‘Heating’ for ‘Boost’

‘Boost’ cannot be initiated from the TRVZB by tapping on the Top Button.

‘Boost’ cannot be initiated from the TRVZB device CAST Card unless there is a button for a switching device (real or virtual) to initiate a scene to set the TRVZB into ‘Boost’. This also means that a TRVZB cannot be set directly to ‘Boost’ by using a Virtual Assistant such as Amazon Alexa.

There is not any indication on a TRVZB device CAST Card showing that the device is in ‘Boost’ other than the OFF Manual and A indicators not highlighted and the Target Temperature displayed as 35 deg C.

The only definitive indication that the TRVZB is in ‘Boost’ is the ‘Boost’ toggle switch indicator within the eWeLink cube card for the device and the TRVZB display showing ‘HI’ if its top knob is tapped.

We have been testing the ‘Boost’ function and feel that it is not really very useful in its current stage of development. It would be useful to understand Sonoff’s long term plans for this feature.

Currently as an alternative for TRVZB ‘Boost’ In eWeLink cube, CAST, or Virtual Assistant (Amazon Alexa) we use a set Target Temperature command to switch TRVZBs from AUTO to Manual with the stated Target Temperature and scenes that execute at 59 minutes past each hour to switch all system TRVZBs to AUTO. This gives a variable temperature boost to a maximum time of 1 hour.

Would be interesting to hear other users experiences and thoughts.

For Raspberry Pi version 1.1, could you please provide a clear photo of the back of the board ? We’d like to get the this board to reproduce the issue, but we don’t have one. Where can we buy or obtain? This issue has indeed been bothering us for a while.

hi ewelink team , when will the new update of Ihost/cubeos will be released or planned ?

many thanks

9

I’m curious too but now nspanel pro employs them.

10

as a matter hub function at cubeos/ihost

Matter Hub

Supported Matter clusters:

  1. Switches and plugs (On/Off Plug-in Units)

  2. Lights, including:

  • Dimmable Light

  • On/Off Light

  • Extended Color Light

  1. Bridge-type devices

  • Devices connected under a Matter Bridge, including:

    • Switches

    • Plugs

    • Light types (Dimmable Light, On/Off Light, Temperature Light, Extended Color Light)

    ** i would like suggest more types such as : locks , smoke and leak sensors , covers , motion and door sensors .

    best regards

Where did you get this information from?

We expect to release the new version in early February 2026. This update will be significant, so testing may take a bit longer. Additionally, there is a flaw in how CUBE processes devices coming from the Matter Bridge, and we will work on optimizing that in the future.
At the current stage, our focus will likely be on enhancing the functionality of adding devices via Matter Bridge to other ecosystems.

We’re trying to address the root cause of this issue currenly. In early Februry 2026 version, will be fixed.

15

Thank you for your thoughtful and valuable suggestions. We have recently discussed, recorded, and adopted them. In the next version, we will add “Boost” and “Temperature Override” modes in CAST, and we will also optimize the valve opening and closing logic. Please stay tuned for these updates, and thank you again!

16

We have officially launched the CUBE documentation site recently, where you can find the relevant information you need. or if there are any additional parts you would like to see included, please let me know. Thank you!

That’s nice, but since it doesn’t work with Matter Bridge, I can’t share devices with NSPP. And NSPP is just a decoration on the wall that can’t be used.

Hi, I’m just getting to know Cube OS, but I want to ask, is it possible to run it without internet access? Really, only locally in the local network?

19

I use it everywhere, the internet is unstable.

20

but how to add WiFi elements that do not support matter without internet and the ewelink add-on which does not support all devices anyway. I also use alternative devices that the application supports but Cube does not
