benqprojector.py's Issues

W1070 starts blocking commands after some time

I've submitted pull request #10 to get this projector functional with this library in home assistant, but I'm running into an inconsistent issue where the integration starts failing after some time (becomes unavailable / fails to set up after restart), and when I manually check projector I find that it has started blocking all commands:

$ telnet projector-esp-link.lan
Trying 192.168.1.96...
Connected to projector-esp-link.lan.
Escape character is '^]'.

>
*pow=?#
*pow=?#

*Block item#
^]
telnet> close
Connection closed.

Once in this state the projector needs to be turned on with the remote / IR blaster to start working again (power cycling didn't even seem to help - only turning it on fixed it), but I'm not yet positive what is triggering this - the power commands should work while the projector is off, and I haven't encountered this issue previously when I've manually controlled the projector over serial (though that could just be because I rarely did so and just got lucky when I did).

I'm wondering if you might have seen this issue before or have any thoughts as to what to try to resolve / further diagnose it?

Some possibilities I've wondered about are if the connection is being interrupted in the middle of a command could the projector get into a bad state? I'm using socat to create a virtual tty that connects to a Wemos D1 Mini over WiFi attached to a RS232 to TTL converter plugged into the serial port, so there are definitely some extra potential points of failure there compared to a direct serial connection that I've used in the past, and I did notice some timeouts when running the 'examine' command... Another thought is could benqprojector be querying a command that had a different meaning or was bugged on the W1070 and puts it into a bad state?

I recognise that this may just end up being a BenQ firmware bug and there might not be anything you can do to help, and won't feel bad if you just close the ticket as not your problem, but any insights you may have would be appreciated.

benq projector W1000 hoping you can help

regex seems too harsh for W1100

In line 117 in benqprojector.py the regex seems too harsh for my W1100.

Some commands do not need a =, for instance \r*auto#\r, \r*zoomi#\r, \r*zoomo#\r, \r*up#\r, \r*down#\r, \r*left#\r, \r*right#\r, \r*enter#\r.
Some responses do not contain a =, for instance the answers for all the above.
Some responses do not contain a #, for instance the answer for \r*ltim=?#\r, see #5

I'm not sure, whether this regex is only used on detecting command echos or also on responses?

lamp time cannot be processed on W1100

With python3 -m benqprojector /dev/virtualcom0 9600 examine --debug, the lamp time cannot be processed, maybe because of the space before the number or the missing # after? For the latter see also #6

Some commands do not provide reading

Some commands don't provide reading, they can only be written.
Example: \r*menu=?#\r on Benq W1100 doesn't work, but \r*menu=on#\r and \r*menu=off#\r do very well.

For them, the function examine doesn't work correctly, it reports false negative:
