Strips LoRa FAQ
You would need an account on a LoRa Network Server (TTN, Chirpstack, Loriot, Actility etc.), as well as a gateway connected to the internet. In the LNS you need to add both the gateway and the Strips to establish a LoRa network.
With average/normal configuration settings in healthy network conditions, battery life will last up to 10 years. Environments with poor network conditions or aggressive configuration settings (very frequent reporting and/or high spreading factor / data rate) will have a negative impact on longevity and may decrease the lifespan to less than 10 years.
Batteries are non-replaceable
If the device is neither in Transport mode or in a joined state, then Strips is in Standby mode. In this state, Strips will send a join request once per day (this can be configured to occur both less and more frequently)
No, the device will always be running
There are 2 ways to reset the device:
- Reset with the manual reset pattern using a magnet: This will cause the device to unjoin the network and reboot the internal firmware. Keep in mind that this will not reset the Strips configuration settings.
- Reset with a configuration payload: By using this method, the configuration parameters will be reset to factory default, and not cause the device to unjoin or reboot. To reset the configuration settings, send '00' to port 11.
Joining and connections
Strips will be able to connect to any properly configured LoRa network with gateways installed. If you come across any compatibility issues, please contact Sensative.
Yes, if you have a gateway that you believe is not compatible with Strips, please contact us.
No, we advise you to delete the device from the current LoRa Network server, perform a manual reset with a magnet and join the Strips in the new LoRa Network Server. The settings the device is configured to will remain the same.
On the next confirmed report from Strips, such as the daily heartbeat, the device will enter Resend mode when there is no connection to the gateway. By default, the device will reset and enter Standby after 7 days of no received ACK. Please view the Resend more section in the user guide for more information.
Take a magnet and place it by the square end of the Strips. If the device is joined and door report/alarm is enabled, the device will flash orange quickly, the Strips is joined. If the door report/alarm is not enabled, there will be not LED flash at all, the Strips is joined. If the device is not joined, the Strips will flash once long red.
Critical messages generated from Strips, such as alarms are always sent as confirmed messages. This means that the device requires an acknowledgement from the LoRa Network Server. If this does not happen due to gateway issues or getting lost in the air, Strips will resend the messages until it receives a response back. The resend interval is 1, 2, 4, 8... minutes up to once per day.
By performing the manual reset pattern and holding the magnet on the round side for 10 seconds on the last swipe, for a visual guide, please view the video below:
Decoding and configuration
Please use our online Strips Configuration Application: https://strips-lora-config-app.service.sensative.net/
The manual reset pattern will only unjoin and reboot the device, the current configuration will remain unchanged.
When joined for the first time, Strips will send the current state of the default enabled reports. These are Door report and Tamper Alarm. For Presence sensors, Presence report is enabled as well.
We offer live decoding in the LoRa Strips configuration app. If you wish to implement a translator into your own app or system, please view following link: https://sensative.com/article/strips-for-lorawan-payload-decoder/
Once Strips has received a configuration downlink, it will respond with a status code. The different codes are as follows:
- 0300: OK
- 0301: Bad settings
- 0302: Bad payload length
- 0303: Value not accepted
- 0304: Unknown command
To reset all Strips configuration settings, send ‘00’ to port 11, or ‘0100’ to port 10. Keep in mind that the reset won’t be effective until the next communication with Strips.
The tamper report is enabled by in the factory default settings and is triggered (true) if there are magnets on both ends of Strips.
The Multi-sensors are configured with the door/window sensor activated as well as Tamper report and a daily heartbeat. Presence will have the same settings as the Multi-sensor, except for the Presence report, which will be active as well with the settings below:
- Presence Poll Interval: 2 minutes
- Presence Threshold: 50
- Presence Timeout: 60 minutes
Mounting and placement
Variants that are designed for outdoor usage can be used outside (+Drip, +Guard, +Oil), whereas indoor devices (Presence, +Comfort) can not.
Mounting Strips on a metal surface will have a negative effect on the radio signals and is therefore not recommended. If you still must mount it on metal, make sure there is padding between the device and the surface.
Strips is not designed to be submerged into water, and will most likely stop functioning after a period of time.
Yes, as long as the temperature is within the limits of: -30°C to +60°C. Keep in mind that due to the metallic construction of fridges and freezers, radio communication will be negatively affected.
Strips +Drip, +Guard and +Oil are designed to handle liquid as long as they are not fully submerged in water during longer periods of time. +Comfort and +Presence are indoor units and should only be used inside and kept away from fluids.
Transportation and delivery
Please view the Transport mode section in the user guide.
Both magnets keep the device in Transport mode, once removed, Strips will exit Transport mode.
During delivery and shelf-time, the device is put into a deep sleep state also known as Transport mode. In this state battery use is negligible. You can find more information about Transport mode in the user guide.
Strips is never switched off once produced. During delivery and shelf-time, the device is put into a deep sleep state also known as Transport mode. You can find more information about Transport mode in the user guide.
