19 == 1.1 ​ What is DMT01 Wireless Meat Thermometer ==
20
21
22 The DMT01 is a (% style="color:blue" %)professional-grade wireless meat thermometer(%%) engineered for accurate, real-time temperature monitoring in commercial cooking environments. Ideal for restaurants, central kitchens, catering services, and food processing facilities, the DMT01 ensures consistent results across various cooking methods—including grilling, smoking, roasting, deep-frying, sous vide, baking, and more. Its precise monitoring helps improve cooking efficiency, ensure food safety, and meet HACCP compliance standards.
23
24 The system consists of two components:
25 - (% style="color:blue" %)Food-grade BLE High-Temperature Probe(%%) – A durable, high-heat resistant probe that measures internal food temperature during cooking.
26 - (% style="color:blue" %)Charging Base with BLE & LoRaWAN Forwarder(%%) – This base not only charges the probe but also acts as a communication bridge. It receives temperature data from the BLE probe and transmits it via the LoRaWAN long-range wireless protocol to your IoT platform or monitoring system.
27
28 With its dual wireless support ((% style="color:blue" %)BLE for close-range/small design(%%) and (% style="color:blue" %)LoRaWAN for long-range data transmission(%%)), the DMT01 is ideal for both home cooking enthusiasts and commercial kitchen environments seeking smart, connected temperature monitoring.

110 To use DMT01 send data to LoRaWAN network, user need to:
111
112 1. Input the OTAA Keys in LoRaWAN Network Server
113 1. Make sure there is LoraWAN network
114 1. Press the button on the DMT01 for more than 3 seconds, DMT01 will start to connect to LoRaWAN network
