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
