KNOT LR8 kit is an out-of-the-box IoT Gateway solution for LoRa® technology *
For ultimate versatility and cost-effectiveness. The first gateway with a CAT-M interface for LoRa®!
We all know the struggle of managing so many devices with different interfaces and communication protocols.. You keep adding new solutions to your setup to keep up, but the older devices are still too good to let them go. How do you integrate all of them in a single system that will serve you right? Easy – you “tie” them together by using the KNOT!
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 handle them all!
An out-of-the-box 863-870 MHz IoT Gateway solution for LoRa® technology, it 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. This kit contains a pre-installed UDP packet forwarder to any public or private LoRa® servers. With the support of 8 different channels, Listen Before Talk (LBT) and spectral scan features this product will astound you with its enticing price point.
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, LoRa®, 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.
This kit can even help you in the most unusual situations. Remember the part about onboard GPIOs? Those pins can be used to read all kinds of analogue sensors, interact with a single-board computer or other custom electronics - hobbyist kits, D.I.Y. robotics... It’s like getting the whole Swiss Army instead of a Swiss Army knife!
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!
* LoRa (from "long range") is a proprietary low-power wide-area network modulation technique. It is based on spread-spectrum modulation techniques derived from chirp spread spectrum (CSS) technology. It was developed by Cycleo of Grenoble, France and acquired by Semtech, the founding member of the LoRa Alliance; it is patented.
LoRa enables long-range transmissions with low power consumption. The technology covers the physical layer, while other technologies and protocols such as LoRaWAN (Long Range Wide Area Network) cover the upper layers. It can achieve data rates between 0.3 kbit/s and 27 kbit/s, depending upon the spreading factor. LoRa devices have geolocation capabilities used for trilaterating positions of devices via timestamps from gateways.

Mikrotik TG-BT5-IN Indoor Bluetooth Tag for Mikrotik KNOT - slim and sleek, perfect for indoor inventory tracking
Bluetooth tags play a huge role in IoT setups, where Bluetooth is used to broadcast the data over short distances. You can use these small devices for proximity-based tracking of various objects. For example, if you have a KNOT gateway in different parts of a construction site, you can use these tags to locate construction tools, electrical equipment, and other assets.
Just attach the tags to the necessary items - and the nearest gateway will sense the tags in its proximity. Exceptionally useful in warehouse logistics – let your cargo inform you as soon as it enters the warehouse! They use so little power that a single built-in 220 mAh battery will last for years.
Once activated, the splash-proof tag will broadcast iBeacon, Eddystone or MikroTik telemetry advertising packets to the gateway (such as the KNOT or any other BLE gateway). These packets contain MAC address used for ID, as well as telemetry data – such as acceleration, tilt and battery charge level. The gateway then pushes the data to the remote server utilizing MQTT or HTTP protocols.
By default, advertisement packets are sent once every 5 seconds, but you can change this value to your liking. For example, if you set the interval to 1 second, the battery will typically last two years. The built-in accelerometers not only detect acceleration (movement), but can also register if the device was dropped or tilted (free-fall detection).

MikroTik TG-BT5-OUT Outdoor Water Proof IP69k Bluetooth Tag - the heavy-duty tag for industrial challenges
This version of our BLE (Bluetooth low energy) tags comes completely sealed, cast in industrial-grade moulds to give it a solid IP69k ingress protection rating. In other words, this tag is dust-tight – nothing gets in, and it is fully protected against close-range high-pressure, high-temperature spray downs. Perfect for industrial telemetry systems or to track all kinds of heavy equipment and materials at a construction site.
Like the indoor version, this tag also supports iBeacon, Eddystone, and MikroTik telemetry formats. There is an NFC encoded MAC address and optional encryption. Unlike the indoor version, the outdoor tag comes with a built-in temperature sensor that can be used for condition monitoring. The ±0.5°C precision can be very useful in cold supply chain logistics.
TG-BT5-OUT features an improved 550 mAH battery that will last around five years (with a reporting interval of 1s). It is suitable for strapping to all kinds of surfaces, and it can handle a temperature range of -20°C to 85°C.
