Hey @DaTiC0 - I've reviewed your changes - here's some feedback:

  • Extract message.payload.decode() into a local variable to avoid multiple decodings and improve readability.
  • Switch to a logging framework instead of print() for better log management and severity levels.
  • Consider handling potential decoding errors (e.g. non-UTF-8 payloads) by wrapping decode() in try/except or using fallback options.

suggestion: Avoid decoding payload multiple times

Decode the payload once into a variable and reuse it for both printing and comparison to improve readability and efficiency.
