echonetlite_homeassistant: Sharp Air Purifier KI-PX70 Stuck at Integration's Initializing Stage

Maybe related to #167

My model is Sharp KI-PX70, and I thought it was similar to KI-HS70 which the README says is supported.

This issue is a bit amusing for me because everything was working fine when I first started using Version 3.8.0-beta9.

Until one day, when I happened to check the homeassistant logs, I noticed an error message indicating a syntax error in this plugin. You can refer to: https://github.com/scottyphillips/echonetlite_homeassistant/commit/623e597dc140f2ccaf4ee39dd04773b7524fd082#r138870175

After manually fixing the code, two additional sensors did appear as expected. Previously, there was only a switch for control and a select for mode selection. However, these two additional sensors have been stuck in a state without any data.

After a while, approximately 15-20 minutes later, the entire integration stopped receiving data. I tried reloading the integration, but the issue persisted.

I enabled debug mode and checked the logs, which I have provided below. Since I’m not as familiar with this project and the ECHONET protocol as everyone else, I wanted to raise this issue and seek your opinions. Thank you.
