Installation Mounting Select the installation place so that the air can flow freely on all sides of the transmitter, representing the air that is to be measured. Avoid heat sources and direct sunlight. Place the device to the measuring location with one of the following ways: • • 5 Place the Kombi-LWUS on any surface with the bottom facing down. Mount the wall holder with two universal countersunk screws (ST 2.5 or ST 3.0). Use applicable length depending wall material.
Power supplies The Kombi-LWUS indicates the powerup by blinking the led next to the micro USB socket. -RHT-DP, -RHT, -RHT-IP42 variants These variants are powered with 3 pcs LR6 batteries (AA 1.5 V alkaline). High quality batteries should be used, for example Energizer EN91. The device is supplied with batteries already installed, so it is ready to be used. The Kombi-LWUS can alternatively be powered with an external supply.
Protecting the settings To protect the settings from being easily adjusted, the configuration menu provides a password box. The password can be formed by using up to 16 characters. From the next MekuWin session, the settings cannot be adjusted without knowing the password. If the displayed status is “Locked”, changes will not be saved to the device. Write the correct password in the “Password input” field and press enter to unlock.
Dust13 sensor variants measure PM1, PM2.5 and PM10. The larger Dust40 sensor measures PM1, PM2.5, PM10 and PM40. The sensor does not need periodic recalibration. If it appears to have dust deposited inside, compressed air can be used with extreme care to blow it clean. Monitor menu In MekuWin Mon-menu, the measurement readings can be monitored. The sensors are kept continuously on. The values update at the rate the sensor can produce new readings.
LoRaWAN settings Conf menu Quality • Unidirectional – uplinks are sent as unconfirmed data with 1 attempt. Acknowledgement is not requested. • Bidirectional – uplinks are sent as confirmed data. Acknowledgement is requested, and up to 3 attempts are used if acknowledgement is not received. DevEUI (readonly) – shows the DevEUI of the device. Note that DevEUI cannot be modified. LoRaWAN credentials These should be only changed if manually provisioning the device to your own system.
Uplink payload structure This information is only relevant for integrating the Kombi-LWUS with the customer’s own cloud platform. Consists of several message types, one message per uplink. All values are LSBF unless otherwise specified. Terms: • • uint8 = unsigned 8-bit integer uint16 = unsigned 16-bit integer Uplink fPort is 2 by default.
Type 5 – RH+T+VOC+DP+CO2 measurements Contains first bitflags and then measurement fields based on the bitflags. The bitflags describe which fields are included; if there’s not a bitflag matching the field number, that field is missing from the message, so for example RHT variants will only have T and Rh bitflags and values. Conversion defines the formula to find the measurement result. Range of possible results and step between possible results (for example with step 0.5 results can be 0.0, 0.5, 1.
Example uplinks Here are some example uplinks to help clarify how the uplink payloads are structured. 050be51d1ce8ff • • • • • Type: 05 -> measurements type 5 Bitflags: 0b = 11 = 1+2+8 = flags 0, 1, 3 -> T, Rh and dP included T: e51d -> 26.53 Rh: 1c -> 14 dP: e8ff -> status 11 01236d500001059c1e • • • • • 12 Type: 01 -> utility type 1 Bitflags: 0x23 = 35 = 32 + 2 + 1 = flags 0, 1, 5 -> Device type, firmware version, calibration date Device type: 6d5000 -> type 20589 Firmware version: 0105 -> v1.
Maintenance Checking the status Press the button to check the status of the Kombi-LWUS. The led located next to the micro USB socket will indicate the status: • • • If the led blinks green, everything is fine, and the remaining battery capacity is estimated to be over 20%. If the led blinks red, the remaining battery capacity is estimated to be below 20%. If the led does not blink at all, the device isn’t working properly.
