it is more a feature request: is it possible to use an optical Head (IR) instead the direct wire connection #5

Open Dolphin1220 opened 1 year ago

Dolphin1220 commented 1 year ago

My electricity meter has an optical interface, which I can read with an IR reading head. The connection is also encrypted, I have the key. The read head has 4 pins TX / RX / GND and 3.3V. the data rate are 9600 baud N81. Is it possible to adapt the code to use the read head instead of a cable connection ?

in vienna we also have the IM350 but without the RJ12 - just checked mine :(

so the only way to get the data is the IR-head or a similar solution.

It would be highly apprecated if you could add IR-head support...

please provide some feedback, if that would be possible.

My ISKRA AM550 (in Vienna) also has no RJ12 interface, only an IR interface. It works with TASMOTA and Hichi read head, but I would like to do it with ESPHome/YAML. I can read the data, but it is in HEX format - I assume encrypted - solution see https://github.com/thealkly/ESPHome-SML-IR-LED/tree/main I have the key from the "Wiener Netze". Does anyone know a working solution or can someone help with the solution based on @ALKLY

I was not able to decode it with ESP-Home, so i bought this: https://cms.shrdzm.com/produkt/smartmeter-modul/ including the readhead: https://cms.shrdzm.com/produkt/ir-lesekopf/ it worked perfect, i can integrate it via mqtt in homeassistant without any problems. Andy

@Dolphin1220 Thank you for your input - then I will (unfortunately) stick with my TASMOTO solution, which I have already integrated into ESPHome. Maybe someone will build such a solution in the future - I hope so ;-)
