Description
SensMax SMX data collectors are advanced devices designed to collect data from SensMax sensors over a radio channel. These collectors serve as the central hub in a wireless sensor network, aggregating data from multiple sensors from various locations. After collecting data, SensMax SMX devices transmit the information to a central server via Wi-Fi or Ethernet, offering flexible connectivity options for various environments and infrastructures.
By supporting the MQTT protocol, these collectors provide reliable real-time data transmission, making them ideal for IoT applications, smart buildings, and remote monitoring systems.
Key features include:
- Wireless data collection from SensMax sensors via radio channel.
- Flexible connectivity via Wi-Fi or Ethernet.
- Support for MQTT protocol for lightweight and efficient data transfer.
- Real-time data transmission to a central server.
Radio frequency options (868 / 915 / 920 MHz)
By default, all LR and SLR series devices (both sensors and collectors) are supplied configured to a frequency of 868 MHz. For regions with other radio frequency standards (USA, Asian countries, etc.) or upon special request, we produce modifications operating at frequencies of 915 MHz and 920 MHz.

Data memory allocation
SensMax SMX data collectors are equipped with non-volatile memory, allowing sensor data to be stored in the absence of an Internet connection. Once the connection is restored, the device automatically transmits all accumulated data to the server.
Data memory allocation depends on the device model.
TS-MODELS (SensMax SMX LR TS, SensMax SMX SLR TS)
All TS-models have up to 80 memory blocks, with each block storing 24 hours of data with 5-minute intervals. However, memory blocks are distributed among the connected sensors: D3 TS bidirectional sensors use 2 memory blocks each, and L3 TS loyalty buttons occupy 3 blocks each.
For example, if one D3 TS sensor is connected, the data collector can store up to 40 days of data with 5-minute intervals. If 10 D3 TS sensors are connected, the collector will be able to store up to 4 days of data for each sensor.
non-TS MODELS (SensMax SMX LR, SensMax SMX SLR, SensMax SMX PRO)
All non-TS models, regardless of the number and type of connected sensors, can store data up to 25 days with an interval of 1 hour.
Settings web page
All device settings are accessible on the built-in settings web page. There are several ways to access the settings page:
Accessing settings page via Ethernet
- Connect the SensMax SMX data collector to a power source.
- Connect the SensMax SMX data collector to your Ethernet network using an RJ-45 cable.
- Connect your laptop or smartphone to the same network.
- Open a web browser and type in the address bar:
http://xxxxxxxxx.local(wherexxxxxxxxxis the collector's serial number. For example,http://051002363.local).
Accessing settings page via Wi-Fi AP (access point)
- Connect the SensMax SMX data collector to a power source.
- Search for available Wi-Fi networks on your laptop or mobile phone.
- Connect to the collector's access point (AP name: "SensMax XXXXXXXXX"). The default password is the same as the collector's serial number. For example, if the collector's access point is named
SensMax 051002363, the default password will be051002363. - Open a web browser.

Ordering Information
Important: Radio frequency compatibility
When ordering equipment (sensors and gateways), make sure they work on the same radio frequency. By default, LR, SLR, and TS devices are shipped tuned to 868 MHz. If you require modifications for 915 MHz or 920 MHz, be sure to specify this when ordering (for example: SensMax SMX LR - 915 MHz). Equipment with different frequencies will not be able to communicate with each other.
