### Routing

#### View or change this node's repeat flag
**Usage:**
- `get repeat`
- `set repeat <state>`

**Parameters:**
  - `state`: `on`|`off`

**Default:** `on`

---

#### View or change this node's advert path hash size
**Usage:**
- `get path.hash.mode`
- `set path.hash.mode <value>`

**Parameters:**
- `value`: Path hash size (0-2)
  - `0`: 1 Byte hash size (256 unique ids)[64 max flood]
  - `1`: 2 Byte hash size (65,536 unique ids)[32 max flood]
  - `2`: 3 Byte hash size (16,777,216 unique ids)[21 max flood]
  - `3`: DO NOT USE (Reserved) 

**Default:** `0`

**Note:** the 'path.hash.mode' sets the low-level ID/hash encoding size used when the repeater adverts. This setting has no impact on what packet ID/hash size this repeater forwards, all sizes should be forwarded on firmware >= 1.14. This feature was added in firmware 1.14

**Temporary Note:** adverts with ID/hash sizes of 2 or 3 bytes may have limited flood propogation in your network while this feature is new as v1.13.0 firmware and older will drop packets with multibyte path ID/hashes as only 1-byte hashes are suppored. Consider your install base of firmware >=1.14 has reached a criticality for effective network flooding before implementing higher ID/hash sizes. 

---

#### View or change this node's loop detection
**Usage:**
- `get loop.detect`
- `set loop.detect <state>`

**Parameters:**
- `state`: 
  - `off`: no loop detection is performed
  - `minimal`: packets are dropped if repeater's ID/hash appears 4 or more times (1-byte), 2 or more (2-byte), 1 or more (3-byte)
  - `moderate`: packets are dropped if repeater's ID/hash appears 2 or more times (1-byte), 1 or more (2-byte), 1 or more (3-byte)
  - `strict`: packets are dropped if repeater's ID/hash appears 1 or more times (1-byte), 1 or more (2-byte), 1 or more (3-byte)
  
**Default:** `off`

**Note:** When it is enabled, repeaters will now reject flood packets which look like they are in a loop. This has been happening recently in some meshes when there is just a single 'bad' repeater firmware out there (prob some forked or custom firmware). If the payload is messed with, then forwarded, the same packet ends up causing a packet storm, repeated up to the max 64 hops. This feature was added in firmware 1.14

**Example:** If preference is `loop.detect minimal`, and a 1-byte path size packet is received, the repeater will see if its own ID/hash is already in the path. If it's already encoded 4 times, it will reject the packet.  If the packet uses 2-byte path size, and repeater's own ID/hash is already encoded 2 times, it rejects. If the packet uses 3-byte path size, and the repeater's own ID/hash is already encoded 1 time, it rejects.

**Default:** `0.2`

---

#### [Experimental] View or change the processing delay for received traffic
**Usage:**
- `get rxdelay`

**Parameters:**
- `value`: Receive delay base (0-20)

**Default:** `0.0`

---

#### View or change the duty cycle limit
**Usage:**
- `get dutycycle`
- `set dutycycle <value>`

**Parameters:**
- `value`: Duty cycle percentage (1-100)

**Default:** `50%` (equivalent to airtime factor 1.0)

**Examples:**
- `set dutycycle 100` — no duty cycle limit
- `set dutycycle 50` — 50% duty cycle (default)
- `set dutycycle 10` — 10% duty cycle
- `set dutycycle 1` — 1% duty cycle (strictest EU requirement)

> **Note:** Added in firmware v1.15.0

---

#### View or change the airtime factor (duty cycle limit)
> **Deprecated** as of firmware v1.15.0. Use [`get/set dutycycle`](#view-or-change-the-duty-cycle-limit) instead.

**Usage:**
- `get af`
- `set af <value>`

**Parameters:**
- `value`: Airtime factor (0-9). After each transmission, the repeater enforces a silent period of approximately the on-air transmission time multiplied by the value. This results in a long-term duty cycle of roughly 1 divided by (1 plus the value). For example:
  - `af = 1` → ~50% duty
  - `af = 2` → ~33% duty
  - `af = 3` → ~25% duty
  - `af = 9` → ~10% duty
  You are responsible for choosing a value that is appropriate for your jurisdiction and channel plan (for example EU 868 Mhz 10% duty cycle regulation).

**Default:** `1.0`
