EDL21 electricity meter bridge (LoRaWAN)
The EDL21 over LoRaWAN bridge is a device that can be used to readout modern utility meters with
standardized infrared "INFO" interface.
These type of meters are called in Germany to be "EDL21"-compatible - hence the name. The meter
outputs over its infrared "INFO" interface a serial protocol conforming to the
Protocol 1.04
(SML). This interface is intended to be used by end-users and
the electricity supplier. The read information normally contains the current consumption values of the
meter and gets interpreted and forwarded by the EDL21 bridge via a LoRaWAN network to web based
applications interested in further processing this data.
Warning
Older meters with "infrared pulse" output are

- Page 6 Timestamps might not represent real time Be aware that the timestamps are generated using the device's internal clock, which does not necessarily represent real time! If you want exact timestamps, you should use the TimeSync feature that synchronises the device's clock over LoRaWAN. Be sure that your network server supports it.
