Description

The newest addition to the MikroTik IoT product family – KNOT – is a truly universal device with exceptional connectivity options and protocol support. It is an IoT Gateway that uses Narrow  Band  and  CAT-M  technology.  Because  of  the  low  cost,  low  bandwidth  cellular  connection, it is supported by countless mobile operators around the globe.

It doesn’t matter whether you have devices that are no longer in production, devices that came out this year, or even some custom solutions by your technician – the KNOT can help you integrate or “tie” them all together in a single system.

KNOT  can  monitor  onboard  GPIOs,  convert  Modbus  protocol  to  TCP,  and  even  forward  Bluetooth packets to TCP/IP network via HTTPS and MQTT.You can use the KNOT as a TCP bridge from wired Modbus sensors to send readings to a Modbus server. Yes, the KNOT brings wireless connectivity to wired sensors and actuators, such as electricity meters and relays.

CAT-M brings better connectivity to host -  reach even previously unavailable places!
It could be used as a backup connection for the Ethernet or as a management channel for your network. NB/CAT-M monthly plan is much cheaper than LTE. Why spend extra money on bandwidth you don’t need? For example, you can manage a KNOT-powered vending machine with temperature and moisture sensors with only a few megabytes per day!

KNOT features so many protocol support and connectivity options:  2.4 GHz wireless, Bluetooth, 2x 100 Mbps Ethernet ports with PoE-in and PoE-out, MicroUSB. Maximum convenience at the lowest cost!

With the Bluetooth interface, you can use the KNOT for asset tracking and telemetry based on Bluetooth advertisement packets. KNOT supports any BLE tag that sends advertisement data. iBeacon, Eddystone or any other format.
It has powerful filters for forwarding only relevant packets and ignoring others.

KNOT is a great tool for most outdoor cabinet IoT applications as well. It comes with a DIN rail mount that allows easy integration with  all  kinds  of  setups:  from  agriculture  and  asset  tracking  to  cold chain monitoring, industrial manufacturing, and so on.

Bring flexible low-cost connectivity to the most remote or tricky areas with the MikroTik KNOT!

How would all this work in real life? Well, let’s imagine a hospital. Lots of expensive assets moving  across  huge  buildings.  Tools,  equipment,  meds,  you  name  it.  Everything  gets  moved around all the time. Usually, hospitals have to spend a lot of resources on inventory checking.

Let’s fix that. Place low-cost Bluetooth tags on all the important items.  Add a KNOT device in  every  storage  room.  Now  the  hospital  management  always  knows  if  the  equipment  is  returned to its place.  Why stop there? You can add temperature sensors to medical supplies and use the KNOT to keep track. The possibilities are endless.
