No command echo received and Unexpected exception: Failed to retrieve projector model on BenQ X3000i

Hi rrooggiieerr, first of all I would like to say a big thank you for writing this integration for Home Assistant. I've been trying to write one myself but I haven't really figured out Python yet.

I am getting the above two errors when trying to add the integration to my HA. The log details are below:

--- No command echo received --- Logger: benqprojector.benqprojector Source: custom_components/benqprojector/config_flow.py:114 Integration: benqprojector First occurred: 10:00:20 PM (6 occurrences) Last logged: 10:10:30 PM

--- End ---

I note that the projector does reply correctly, but somehow an unexpected response was detected, preventing the script from going further. Please let me know what I can do to help troubleshoot the issue.

Hi @c1em3ntchua, great to see someone is already trying out my BenQ integration, especially since it's only 5 day's on Github. The current version on Github is actually not very stable, but a new version is coming very soon which wil probably be workable and has many more features. I'll get back to you when that's the case

[c1em3ntchua]

Thanks a lot @rrooggiieerr, appreciate the reply. Looking forward to the update :)

Off topic, but would appreciate if you could add a smartsystem into the sources list. Edit: actually, let me see if I can contribute on my side.

[rrooggiieerr]

@c1em3ntchua, I'm not sure what you mean by a smartsystem, but the library I use (and also wrote) in this integration, uses a per projector model configuration for supported commands and modes.

https://github.com/rrooggiieerr/benqprojector.py

Currently only my own model W1110 is in there, but if you send me a list of supported modes I can add a configuration for your projector.

Actually the BenQ Projecotr library has an undocumented detection mode which detects what is supported by your model

[c1em3ntchua]

@rrooggiieerr the X3000i manual is available here.

smartsystem seems to be the name BenQ assigns to the 3rd HDMI for an internal Android TV stick.

I did notice the detection mode in the code. Pretty cool feature!

[rrooggiieerr]

@c1em3ntchua , new release of the BenQ Projector library and HA integration should solve your initial issue.

[c1em3ntchua]

Hey @rrooggiieerr, the new library does solve the initial issue, but other issues pop up afterwards. I believe it's library related.
