Temperature threshold alert WiFi
Temperature threshold alert WiFi is similar to the original mode as it sends an alert every time the measured temperature is above or below any of three temperature thresholds A, B or C. The thresholds are encoded in SimpleTemp. All mode-specific events are sent with 3 MAC addresses for better localisation precision.
Temperature threshold alert WiFi
Hex value: 0x1B
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.

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.

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 threshold alert WiFi messages:
To set this mode, the downlink needs to include this mode register setting: 011B
The uplink messages need to begin with the mode hex as the first byte: 1B
When arming the device, you should see this message: 1B10
When the device is armed, it should send you these two bytes: 1B11
If you disarm the device via long press, you should receive this message: 1B14
