Reed switch on/off WiFi
Reed on/off WiFi 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 as no magnetic field is detected anymore. All mode-specific events are sent with 3 MAC addresses for better localisation precision.
Reed switch on/off WiFi
Hex value: 0x19
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.
Register (hex) | Default (hex) | Delta (hex) | Delta information |
Sleep time (0x04) | 1 minute (0x41) | 12 seconds (0x0C) | Sleep time decreased |
Reed contact detection delay (0x4B) | 0 seconds (0x00) | 5 seconds (0x05) | Detection delay active |
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 |
0x94 | Reed contact on with WiFi 1/2 | 1 | Reed contact switched on because of magnet presence, sent with 3 MAC addresses |
0x95 | Reed contact on with WiFi 2/2 | 1 | |
0x96 | Reed contact off with WiFi 1/2 | 2 | Reed contact switched off because of magnet absence, sent with 3 MAC addresses |
0x97 | Reed contact off with WiFi 2/2 | 2 |
Registers relevant for this mode:
Hex | Register name | Default value (hex) |
0x37 | Reed contact measurement period | 1 second (0x10) |
0x4B | Reed contact detection delay | 0 seconds (0x00) |

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 messages:
To set this mode, the downlink needs to include this mode register setting: 0119
The uplink messages need to begin with the mode hex as the first byte: 19
When arming the device, you should see this message: 1910
When the device is armed, it should send you these two bytes: 1911
If you disarm the device via long press, you should receive this message: 1914
