Hello everyone,

===== My Context =====  
I adopted Gladys by installing it on a Raspberry 4 (bookworm + Deskpi Pro case + 120GB SSD)  
I deployed the Switchbot integration to collect six “Meter plus” probes  
Everything works perfectly.  
To continue my experiments, I bought Matter devices from Ikea and deployed the MaterBridge extension  
My Matter over Thread devices: a KAJPLATS bulb, a GRILLPLATS outlet, and two BILRESA remotes

To have a “Border Router Thread,” I deployed OpenThread in a Docker container and flashed an nRF52840 dongle (MakerDiary MDK USB Dongle) with the RCP firmware (openthread/ot-nrf528xx).  
All necessary shell scripts and explanations are in the public repository “[gladys\_openthread](https://github.com/ogattaz/gladys_openthread)” on GitHub

========= The Situation =========  
I have a Gladys instance with MatterBridge deployed.  
I have a functional OTBR (see [the validation report](https://github.com/ogattaz/gladys_openthread/blob/main/doc/validate-otbr-persistence.md))  
I cannot “commission” my Ikea Matter devices

========= Why? =========  
A Matter over Thread device (GRILLPLATS, KAJPLATS, BILRESA) receives its Thread identifiers **during Matter commissioning** , which begins with an encrypted exchange **over Bluetooth LE** (PASE) between the device and a commissioner.

This is exactly what Gladys cannot do, and what the OTBR cannot do either.

========= Solution? =========  
My readings of documentation, forums, and discussions with Mistral lead me to the solution: **chip-tool**  
I found this:

- **chip-tool** is the reference tool for the Matter project but is experimental: it works, it’s documented, it’s the path used by the Gladys community, but you’re off the beaten track.
- The 4 pairings must be done one by one, device by device (pairing mode on each).
- Once the devices are in Gladys, you will need to keep chip-tool installed (or at least its storage) for future needs (recommissioning after factory reset).

Has anyone here already experimented with **chip-tool**?

Thanks in advance for your help.
