Temperature change alert WiFi SuperLocal

Temperature delta alert WiFi SuperLocal 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 up to 5 MAC pointers and the respective RSSI for very precise localization.

Temperature change alert WiFi SuperLocal

Hex value: 0x58

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
0xD1	Temperature delta alert WiFi Precise	1	Temperature above the predefined delta, sent with 5 MAC pointers and RSSI
0xFC	MAC storage readout	No	One pointer and its assigned MAC address sent

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)
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
0x11	Temperature delta alert	Original Temperature delta alert, no WiFi
0x1C	Temperature delta alert WiFi	Basic WiFi version of Temperature delta alert
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

Here’s what’s important for Temperature delta alert WiFi Precise messages:

• To set this mode, the downlink needs to include this mode register setting: 0158

• The uplink messages need to begin with the mode hex as the first byte: 58

• When arming the device, you should see this message: 5810

• When the device is armed, it should send you these two bytes: 5811

• If you disarm the device via the long press, you should receive this message: 5814
