1. General Information

The Dzer0 Gateway 4X is a device that can be used to readout modern utility meters with standardized infrared "INFO" interface.

The meter outputs over its infrared "INFO" interface a serial protocol conforming to the Smart Meter Language Protocol 1.04 (SML) or IEC 62056-21 protocol. This interface is intended to be used by end-users and not for billing purposes of the electricity supplier.

The read information normally contains the current consumption values of the meter and gets interpreted and forwarded by the Dzer0 Gateway 4X via a LoRaWAN or Nb-IoT to web based applications interested in further processing this data.

a. Top Features

 LoRaWAN 1.0.x and 1.1 network servers supported

 LoRaWAN time synchronisation

Configuration via USB or remotely via our IoT platform or a LoRaWAN downlink

 Compatible with many electrical utility meters

 Configure up to 25 Obis Codes to be read

 RGB Status LED

 Variant with external power-supply available on request

b. Compatible utility meters

Any meter that adheres to the standard can be read. The following list contains meters that we successfully tested.

2. Quickstart

1. Connect to the device with the Lobaro Tool using the Lobaro Config Adapter
2. Under Configuration click "Reload Config" and change the fields ReadCron and ObisCode as you need followed by clicking on "Write to Device", here you can see a configuration example.
   
3. Register the device in your LoRaWAN network
4. Connect Saft LSH-20 (Artikel Nr. 3000581) D-cell Battery via XH connector 
5. If not connected to anything the red LED will start blinking as long as no data is received, after 1 minute it will sleep for 15 seconds after every 5 retries
6. Tighten the screws and install the bridge beside your electric meter
7. Place the Dzer0 opto head on the "Info" interface
8. As soon as the Dzer0 receives data its green LED will light up for 5 seconds, when connected to a LoRa Network its blue LED will light up for 5 seconds
9. Check the sent data (port 3), if payload is zero the Dzer0 was not able to read data, recheck proper alignment

3. Configuration

The configuration is done using Lobaro Maintenance Tool and the Lobaro USB PC adapter.

4. LoRaWAN

The connection to the LoRaWAN network is defined by multiple configuration parameters. This need to be set according to your LoRaWAN network and the way your device is supposed to be attached to it, or the device will not be able to send any data.
