# Reed switch on/off WiFi SuperLocal

Reed switch on/off WiFi SuperLocal is similar to the original mode as it sends a message when the reed contact is switched on by a magnet and also sends one when the sensor is switched off because the nearby magnetic field is no longer detected. All mode-specific events are sent with up to 5 MAC pointers and the respective RSSI for very precise localization.

### Reed switch on/off WiFi SuperLocal

**Hex value:** 0x55

**Use cases:** Garage doors, warehouse doors, fridges, anything where reporting contact is important

**Devices that support this mode:** SimplePack Plus

**Required sensors:** Reed contact, WiFi module

**Mode-specific deltas:**

**Deltas** are mode-specific register values different from *register default values*.

**Mode-specific events (uplink messages):**

For more information on what uplink messages (***mode-independent events***) and additional data from various sensors in the device (***appended payload***) can be sent regardless of mode and how to fine-tune message behavior (***alerts***), see *Mode-independent information and events.*

| **Hex** | **Event name**        | **Alert** | **Event information**                                                                    |
| ------- | --------------------- | --------- | ---------------------------------------------------------------------------------------- |
| 0xC4    | Reed on WiFi Precise  | 1         | <p>Reed switched on because of magnet presence,<br>sent with 5 MAC pointers and RSSI</p> |
| 0xC5    | Reed off WiFi Precise | 2         | <p>Reed switched off because of magnet absence,<br>sent with 5 MAC pointers and RSSI</p> |
| 0xFC    | MAC storage readout   | No        | One pointer and its assigned MAC address sent                                            |

**Registers relevant for this mode:**

| **Hex** | **Register name**            | **Default value (hex)**                                                                                                                                                                         |
| ------- | ---------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 0x4B    | Reed contact detection delay | 0x00                                                                                                                                                                                            |
| 0xFC    | MAC storage eraser           | **No default value** - After this register hex, you can send up to 7 MAC pointers (0x01-0x80) to the device and then the respective MAC addresses will be deleted from the internal MAC storage |
| 0xFD    | MAC storage reader           | **No default value** - After this register hex, you can send up to 7 MAC pointers (0x01-0x80) to the device, the respective MAC addresses will be uplinked as the same number of *0xFC events*  |

**Similar modes:**

| **Hex** | **Mode name**          | **Description**                           |
| ------- | ---------------------- | ----------------------------------------- |
| 0x0C    | Reed on/off            | Original version of Reed on/off, no WiFi  |
| 0x19    | Reed on/off WiFi       | Basic WiFi-enabled version of Reed on/off |
| 0x37    | Reed on/off WiFi Atlas | WiFi Atlas version of Reed on/off         |

**Switching to mode, arming, and disarming information:**

Follow the *Basic Operations With SimpleHw Devices guide*, where you can also find information about LED behavior, relevant Sigfox messages, and more.

Here’s what’s important for **Reed on/off WiFi Precise** messages:

* To set this mode, the downlink needs to include this mode register setting: **0155**
* The uplink messages need to begin with the mode hex as the first byte: **55**
* When arming the device, you should see this message: **5510**
* When the device is armed, it should send you these two bytes: **5511**
* If you disarm the device via the long press, you should receive this message: **5514**
