I would like to transfer the data from my smart meter (ISKRA, optical interface conforming to IEC 62056-21) into openHAB (openHABian, 3.2.0-SNAPSHOT - Build #2583, Raspberry Pi 4).
My requirements for the interface smart meter → openHAB are:
- physical interface smart meter <-> interface head must look like the device on IR Schreib/Lesekopf USB (Optokopf)-ART0027 (several variants can be found here: hardware:controllers:ir-schreib-lesekopf [wiki.volkszaehler.org])
- device must be battery operated and battery life must be maximized
- device mustn’t contain any secrets (it might be stolen)
- device must send the data via RF
AFAIU, depending on the interface hardware chosen, the following technologies could be used for integration into openHAB:
- Z-Wave Binding
- ZigBee Binding
- RFXCOM Binding
- Smart Meter Binding
- MQTT Binding
- openHAB REST API
I’m open to suggestions for the hardware (DIY or COTS) - thanks in advance.
BTW, is anyone using this device: Electricity Meter Interface - smart Zigbee meter for home electricity monitoring - frient?
Edit: seems to be a rebranded Develco product: External Meter Interface - Real-time measurement
