Hello,
Still looking for working way to integrate my BENQ TK700STi projector to work with HA. I have tried BENQPROJECTOR-SERIAL integration (worked partially - missed important thing like input select). Have tried as well BENQPROJECTOR (v.007 does not have input selection, beta v.008 does not recognize any com port in my system - it see them all but cannot connect any, including the one that v.007 connected). Unfortunately both people who developed this abandoned their projects and cannot assist anymore.
Tried as well to use bare commands on ttyUSB1 (or as other like /dev/serial/by-id/usb-1a86_USB2.0-Ser_-if00-port0 ). This worked in the way that initially projector accepted commands (without giving back status) till some point in time. Now projector accepts one or two first sent commands and then looks like anything is hitting the projector.
The command I try to use looks like (this one to power off):
echo -e -n '\r*pow=off#\r' > /dev/serial/by-id/usb-1a86_USB2.0-Ser_-if00-port0
Any idea ? I believe that BENQ serial from yaymuffins worked the best - only missing thing there was to implement input select and instead of having switch attributes, having sensors who display projector status. I am really keen to help with testing and with my all poor programming and testing skills to build one thing that will finally works instead of having a bunch of not working ones.
