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. 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, such as electricity meters and relays.
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 liquid 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, Micro-USB. 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.
Narrow Band and CAT-M technology is supported by many operators around the world!
