If you have a new matter device for which there is no PAA yet or the manufacturer isn’t wiling to provide you with one and you get:
CHIP_ERROR [chip.native.CTL] Failed in verifying 'Attestation Information' command received from the device: err 101. Look at AttestationVerificationResult enum to understand the errors
CHIP_ERROR [chip.native.CTL] Error on commissioning step 'AttestationVerification': 'src/controller/CHIPDeviceController.cpp:1145: CHIP Error 0x000000AC: Internal error'
CHIP_ERROR [chip.native.EM] Failed to send Solitary ack for MessageCounter:19271811 on exchange 23003i with Node: <0000000000000000, 0>:src/messaging/ExchangeContext.cpp:99: CHIP Error 0x00000002: Connection aborted
WARNING [root] Failed to commission: src/controller/CHIPDeviceController.cpp:1145: CHIP Error 0x000000AC: Internal error
You can follow these steps:
- Install Advanced SSH & Web Terminal add on and unselect Protection mode
- Identify which
chipversion the python matter server is currently using:
$ docker exec -it $(docker ps -f name=addon_core_matter_server -q) bash
$ pip freeze | grep chip
home-assistant-chip-clusters==2024.5.2
home-assistant-chip-core==2024.5.2
$ exit
- Build a modified version of
home-assistant-chip-coreandhome-assistant-chip-clusters. If it’s2024.5.2you can skip these steps and use my built files
3.1. Fork GitHub - home-assistant-libs/chip-wheels: Python Matter Device Controller and make sure you select all branches, not just main
3.2. Navigate to Actions tab and Enable workflows
3.3. Create a new branch from the 2024.5.2 tag (replace with current version)
3.4. Upload chip-wheels/8766-Bypass-attestation-verification.patch at 8a5ec21d114010723cf428ffe79e244da7562390 · tronikos/chip-wheels · GitHub to your new branch
3.5. Create a new release from your new branch
3.6. Once the workflow finishes you will have some whl files in the release, example
pip installthe above whl files. Open Advanced SSH & Web Terminal (replace URLs with yours)
mkdir /tmp/chip
cd /tmp/chip
wget https://github.com/tronikos/chip-wheels/releases/download/2024.5.2b1/home_assistant_chip_clusters-2024.5.2b1-py3-none-any.whl
wget https://github.com/tronikos/chip-wheels/releases/download/2024.5.2b1/home_assistant_chip_core-2024.5.2b1-cp37-abi3-manylinux_2_31_x86_64.whl
docker cp /tmp/chip addon_core_matter_server:/tmp
docker exec -it $(docker ps -f name=addon_core_matter_server -q) bash
pip install /tmp/chip/*.whl
# Identify process listening at port 5580
ss -ap | grep 5580
# Replace pid with the output of the previous command
kill 126
# matter server should restart using the modified libraries
-
Pair your device with Home Assistant.
-
Once paired restart the Matter Server addon. Modifications will be lost and the device should remain paired.
