Matter ID Lookup

Logs, packet captures and device reports are full of numbers like 0x0101, 257 and 0x0016. Paste one into the box below to find out whether it is a cluster, a device type or a global attribute. Hex, decimal and names all work.

Is a Cluster ID always two bytes?

No. In the Matter specification a Cluster ID is a 32-bit (4-byte) number. The upper 16 bits are a vendor prefix and the lower 16 bits are the number:

0x0000_0101
  │    └─ number 0x0101 (Door Lock)
  └────── vendor prefix 0x0000 (0 = Matter standard)

Every standard Matter cluster has the prefix 0x0000, so people drop the leading zeros and write 0x0101. It looks like two bytes, but that is just shorthand. A vendor-specific cluster cannot drop it: its prefix is the vendor ID, e.g. 0x1234_FC00 is the first private cluster of vendor 0x1234.

Attributes, commands, events and device types use the same "prefix + number" structure, each with its own number range:

Field	Size	Standard range (prefix 0x0000)	Vendor-specific range	Example
Cluster ID	32-bit	`0x0000` – `0x7FFF`	`0xVVVV_FC00` – `0xVVVV_FFFE`	`0x0101` Door Lock
Attribute ID	32-bit	`0x0000` – `0x4FFF`; global `0xF000` – `0xFFFE`	`0xVVVV_0000` – `0xVVVV_4FFF`	`0x0000` LockState
Command ID	32-bit	`0x00` – `0xFF`	`0xVVVV_0000` – `0xVVVV_00FF`	`0x00` LockDoor
Event ID	32-bit	`0x00` – `0xFF`	`0xVVVV_0000` – `0xVVVV_00FF`	`0x00` DoorLockAlarm
Device Type ID	32-bit	`0x0000` – `0xBFFF`	`0xVVVV_0000` – `0xVVVV_BFFF`	`0x000A` Door Lock
Endpoint ID	16-bit	`0` – `0xFFFE` (0 is always the root node)	—	`1` application endpoint
Vendor ID	16-bit	Assigned by CSA; `0xFFF1` – `0xFFF4` are for testing	—	`0xFFF1` test vendor

The same number means different things in different fields

0x0101 in a cluster_id is the Door Lock cluster, but in a device_type it is a Dimmable Light. Each kind of ID has its own numbering. When you see a number, first check which field it appears in, then look it up.

Decimal or hexadecimal?

The protocol carries plain integers; the display format depends on the tool. chip-tool logs often print 0x0000_0101, while Home Assistant diagnostics use decimal 1/257/0 (endpoint/cluster/attribute). 257 and 0x0101 are the same number. The lookup box accepts both; plain digits are read as decimal.

Device Type ID reference

Device types are listed in each endpoint's Descriptor.DeviceTypeList. The table below lists all 95 standard device types in the current release. The class describes its role:

Node — one per device, on root endpoint 0 (e.g. Root Node)
Utility — a helper type layered on top of others (e.g. Power Source, Bridged Node)
Simple — an actual device function (e.g. Door Lock, lights, sensors)
