Temperature change alert WiFi

Temperature delta alert WiFi is similar to the original mode as it sends an alert every time the measured temperature is above the predefined temperature delta. The delta is encoded in SimpleTemp. The mode-specific event is sent with 3 MAC addresses for better localisation precision.

Temperature change alert WiFi

Hex value: 0x1C

Use cases: Monitoring any environment that requires constant temperature in a certain range; labs, factories, warehouses, swimming pools and more

Devices that support this mode: SimplePack Plus

Required sensors: Either temperature sensor (ambi or precise, precise is preferable), WiFi module

Mode-specific deltas:

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

Register (hex)	Default (hex)	Delta (hex)	Delta information
0x0D	0x00	0x40	Temperature sent with appended payload
0x34	0x00	0x43	Temperature measuring turned on

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
0xB6	Temperature delta alert with WiFi 1/2	1	Temperature above the delta, sent with 3 MAC addresses
0xB7	Temperature delta alert with WiFi 2/2	1

Registers relevant for this mode:

Hex	Register name	Default value (hex)
0x2F	Temperature delta	2°C (0x08)
0x34	Temperature measurement period	0 seconds (0x00), delta: 3 minutes (0x43)
0x4D	Temperature detection delay	0 seconds (0x00)

Similar modes:

Hex	Mode name	Description
0x11	Temperature delta alert	Original version of Temperature delta alert, no WiFi
0x43	Temperature delta alert WiFi Atlas	WiFi Atlas version of Temperature delta alert
0x58	Temperature delta alert WiFi Precise	WiFi Precise version of Temperature delta alert

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 Temperature delta alert WiFi messages:

• To set this mode, the downlink needs to include this mode register setting: 011C

• The uplink messages need to begin with the mode hex as the first byte: 1C

• When arming the device, you should see this message: 1C10

• When the device is armed, it should send you these two bytes: 1C11

• If you disarm the device via long press, you should receive this message: 1C14
