Sentrius RG1xx + RS1xx IoT Starter Kit

Under Development


The IoT is all about getting data to the cloud and taking critical actions based on the information in the world around us. Our RG1xx Gateway and RS1xx Sensors make it effortless to prototype your long-range Temperature/Humidity and Open/Closed applications and start gathering meaningful data today.

The kit contains: 

  • 1x Sentrius RG1xx LoRaWAN Gateway + Wi-Fi / Ethernet
  • 1x Sentrius RS1xx Sensor  (featuring Temp/RH + Open/Closed sensing capabilities)
  • Open/Closed cable assembly
  • Our free AWS-based sensor payload decoders, converting binary sensor data into meaningful information
  • Power adapter

The combination makes it easy to gather sensor data and send it as far as 10km in open air to our gateway, where it can be sent to the cloud via Wi-Fi or Ethernet.

The RG1xx included within the Starter Kit is configurable with many popular packet forwarders, such as Semtech Basics Station, UDP forwarder, and compatible with cloud services such as AWS IoT Core for LoRaWAN, The Things Network, ChirpStack and Senet.

RS1xx sensors are easy to install, last for years on two AA batteries and are configurable over our mobile application.

As AWS Qualified Devices, the RG1xx and RS1xx are easy to quickly register with AWS IoT Core, eliminating the need to manage a LoRa Network Server and accelerating IoT application development

Can AS923 and AU915 networks coexist in the same area?

Yes, as long as they are operating on different networks such that AS923 sensors talk to the AS923 gateway and vice versa for AU915 devices. 

Can the RS1xx AS923 (455-00063) work with an AU915 gateway which uses overlapping channels to AS923?

No, an RS1xx AS923 sensor will not work with an AU915 gateway because it cannot receive the downlink packets due to differing bandwidth and frequency plans used and therefore will drop off the network.

What is IP rating

IP stands for Ingress Protection. Its a standard we use to check the sealability of a product once it is installed.

It is composed as IP## , where first digit is for dust/solid objects and the 2nd digit, is for liquids.
Here is the meaning for each numerical code:

First Digit Description
0 No protection
1 Ingress of solid object diameter 50 mm is protected
2 Ingress of solid object diameter 12.5 mm is protected
3 Ingress of solid object diameter 2.5 mm is totally protected
4 Ingress of solid object diameter 1.0 mm is totally protected
5 Protected against harmful dust
6 Totally protected against dust

2nd Digit Description
0 No protection no protection against liquid object No test
1 Protection against water drop vertically
2 Protection against water drop 15° Tilt from its normal position
3 Protection against water spray 60° from the vertical direction
4 Protection from water splash from all direction
5 Protection from water jets from all direction
6 Protection from strong water jets from all direction
7 Protection from water dip 1 m depth water for 30 min
8 Protection from water sink should be decided between customer and manufacturer

Can the RG1xx UI be accessed on a cellular network

If you have normal RG1xx (non LTE version) and add Ethernet to Cellular bridging capability, you can access to RG1xx UI via port forwarding but with the following requirement

  • need to forward whatever external port to internal port 443 to reach the gateway on that bridging device.
  • Cellular provider allows incoming connections on that port.


What is the temperature range for the RS1xx sensors

While the standard RS1xx (455-0001 for North America) can support down to -40°C and RS1xx external sensor (455-0070 for North America) can support down to -55 °C, typical AA batteries do not perform well at below -25 °C. Industrial grade of AA batteries may support lower temperature but they are significantly more expensive that off the shelf standard AA batteries. 

What LoRaWAN MAC version does the RS1xx support?

LoRaWAN version: MAC V1.0.2
Regional Parameters version: PHY V1.0.2 REV B

Where are the access keys for the gateway in TTI (The Things Industries) v3?

The access keys used in TTN v2 are not used anymore in TTN v3 the API key is used instead. Follow the below steps to create an API Key for an application from The Things Stack Console.


  1. Navigate to your application.
  2. Select the API Keys section on the left menu and click the + Add API Key button.
  3. Fill in the Name and select the Rights of your API key.
  4. Click on the Create API Key button in order to create the API key. This will open the API key information screen.


Note: Please make sure to save your API key at this point because it will no longer be retrievable after you leave the page.

How fast can the RS186/RS191 detect a change of the door magnet open/close sensor?

The latency of the RS1xx Sentrius LoRa sensor with external magnet open/close sensor is limited by the following reasons:

1) The RS1xx uses two internal dwell times to detect a door open and close. These can be set in the Sentrius smartphone app to a minimum of 5 seconds (which is also the default setting). So any state change faster than 5 seconds will be suppressed and a change or the open/close sensor state won't be transmitted faster than 5 seconds.

2) Independent of the dwell time the RS186 (EU868 region) faces a minimum LoRa uplink interval due to regulatory 1% duty cycle limitations of the 868MHz frequency band. At the maximum data rate (SF7BW125) the airtime is roughly 60msec, which then adds a dead time of 99x60msec=5.94sec. So from this we get a minimum cycle time of roughly 6 seconds. At the minimum data rate (SF12BW125) the airtime is roughly 1480msec plus a dead time of 99x1480msec=2.4min giving a minimum cycle time of roughly 2.5min.

So the latency of a door open/close state detection plus transmission for the RS186 would be 6 seconds at best case (maximum LoRa data rate SF7BW125) and 2.5min at worst case (minimum LoRa data rate SF12BW125).

The latency of the RS191 is not limited by duty cycle restrictions and hence end up at 5 seconds latency purely due to dwell time.

How many end-devices can a LoRaWAN gateway support?

End-devices do not actually make a connection with a gateway. End-devices broadcast to all gateways within range and the gateway forward packets to a network server if it can hear them. So, a gateway does not have a hard number for supporting devices and it is rather dependent on how much bandwidth a gateway can support. For example, factors such as payload size, interval of each data transmission or data rate being used can affect how much air time is consumed and therefore the gateway processes. Also environment factors should be considered.   

It's normally best to experiment with real devices in actual sites in order to figure out how many devices can transmit data without much data loss, using desired configuration/setup.

Why are the LEDs of my RS1xx with external temperature probe constantly on and it does not join the LoRaWAN network?

With the 1-Wire Digital Thermometer Probe, a connection problem at power up is indicated by both LEDs on the front panel being
constantly on. This is a visual indicator to the user that there is a communication issue between the sensor and the probe.

Please check the connector/plug of the external temperature probe for proper connection as well as its cable for mechanical damage.
