AM550 esphome custom component #4

Open rippinsail opened 3 months ago

rippinsail commented 3 months ago

Hi, I have an AM550 smartmeter by WienerNetze which needs a decryption key. I already managed to receive the encrypted IR data in realtime with ESPhome and also to manually decrypt the enrypted data blocks by using code snippets from this repository: https://github.com/tofuSCHNITZEL/wiener_netze_smartmeter.git

My next step would be to write a custom component for ESPhome which I never did before. I just found that you already did that (just not for the AM550) and it would be an honor for me to do some collaboration on that topic. Thanks

I don't really remember why I wrote that tthhe 550 is unsupported, but you could try my component and add

logger:
  level: VERBOSE

to your esp config to see what parts work.

great, thanks a lot, I will try it this week and let you know about the outcome

Hi, I activated verbose logs and received the following below. The encryption key is correct, I managed to decrypt plausible data with my manual python script. Thankful for any advice. cheers
